This timeline of science and engineering in the Islamic world covers both the classical Islamic Golden Age (usually dated from the 7th to 16th centuries) and the post-classical period (after the 16th century). From the 19th century onwards, the advances by Muslim scientists and engineers occurred both within and outside of the Islamic world. All year dates are given according to the Gregorian calendar except where noted.

7th century

  • 610 - 632 [astrology] Several hadiths attributed to Muhammad show that he was generally opposed to astrology as well as superstition in general. An example of this is when an eclipse occurred during his son Ibrahim ibn Muhammad's death, and rumours began spreading about this being God's personal condolence. Muhammad is said to have replied: "An eclipse is a phenomenon of nature. It is foolish to attribute such things to the death or birth of a human being."[5][unreliable source?]
  • 610 - 632 [medicine] Muhammad is reported to have made the following statements on early Islamic medicine: "There is no disease that Allah has created, except that He also has created its treatment";[6] "Make use of medical treatment, for Allah has not made a disease without appointing a remedy for it, with the exception of one disease, namely old age";[7] "Allah has sent down both the disease and the cure, and He has appointed a cure for every disease, so treat yourselves medically";[8] "The one who sent down the disease sent down the remedy."[9] The belief that there is a cure for every disease encouraged Muslims at the time to seek out a remedy for every disease known to them.
  • 610 - 632 [medicine, pathology] Early ideas on contagion can be traced back to several hadiths attributed to Muhammad, who is said to have understood the contagious nature of leprosy, mange, and sexually transmitted disease.[10][dubiousdiscuss] These early ideas on contagion arose from the generally sympathetic attitude of Muslim physicians towards lepers (who were often seen in a negative light in other ancient and medieval societies) which can be traced back through hadiths attributed to Muhammad and to the following advice given in the Qur'an: "There is no fault in the blind, and there is no fault in the lame, and there is no fault in the sick."[11][dubiousdiscuss]

8th century

  • 700s - [ceramics, pottery] From the eighth to eighteenth centuries, the use of glazed ceramics was prevalent in Islamic art, usually assuming the form of elaborate pottery.[15] Tin-opacified glazing was one of the earliest new technologies developed by the Islamic potters. The first Islamic opaque glazes can be found as blue-painted ware in Basra, dating to around the 8th century.[16]
  • 715 - 815 - [alchemy] Geber, also a Muslim alchemist, introduces theories on the transmutation of metals, the philosopher's stone, and Takwin, the artificial creation of life in the laboratory. He also further developed the five classical elements into seven elements by adding two metals: sulfur (‘the stone which burns’ that characterized the principle of combustibility) and mercury (which contained the idealized principle of metallic properties) as 'elements'.[25]
  • late 700s - early 800s - [musical science] Mansour Zalzal of Kufa. Musician (luth) and composer of the Abbasid era. Contributed musical scales that were later named after him (the Mansouri scale) and introduced positions (intervals) within scales such as the wasati-zalzal that was equidistant from the alwasati alqadima and wasati al-fors. Made improvements on the design of the luth instrument and designed the Luth. Teacher of Is-haq al-Mawsili.

9th century

  • 800s - [chemistry, petroleum] Oil fields first appear in Baku, Azerbaijan, and generate commercial activities and industry. These oil fields, where oil wells are dug to get the Naft (naphta, or crude petroleum), are described by geographer Masudi in the 10th century and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads.
  • 800s - [legal science, education] The origins of the doctorate dates back to the ijazat attadris wa 'l-ifta' ("license to teach and issue legal opinions") in the medieval Islamic legal education system, which was equivalent to the Doctor of Laws qualification and was developed during the 9th century after the formation of the Madh'hab legal schools. To obtain a doctorate, a student "had to study in a guild school of law, usually four years for the basic undergraduate course" and ten or more years for a post-graduate course. The "doctorate was obtained after an oral examination to determine the originality of the candidate's theses," and to test the student's "ability to defend them against all objections, in disputations set up for the purpose" which were scholarly exercises practiced throughout the student's "career as a graduate student of law." After students completed their post-graduate education, they were awarded doctorates giving them the status of faqih (meaning "master of law"), mufti (meaning "professor of legal opinions") and mudarris (meaning "teacher"), which were later translated into Latin as magister, professor and doctor respectively.[62]
  • 820 - [mathematics] Muhammad ibn Mūsā al-Khwārizmī (Persian name: خوارزمي, Arabicized name الخوارزمي al-Khwarizmi, Latinized name Algorithm) wrote the Hisab al-jabr w'al-muqabala (Calculus of resolution and juxtaposition), more briefly referred to as al-jabr, or algebra. "Algebra was a unifying theory which allowed rational numbers, irrational numbers, geometrical magnitudes, etc., to all be treated as "algebraic objects". It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before."[70] As Rashed writes: "Al-Khwarizmi's successors undertook a systematic application of arithmetic to algebra, algebra to arithmetic, both to trigonometry, algebra to the Euclidean theory of numbers, algebra to geometry, and geometry to algebra. This was how the creation of polynomial algebra, combinatorial analysis, numerical analysis, the numerical solution of equations, the new elementary theory of numbers, and the geometric construction of equations arose."[71][72]
  • 820 - [mathematics] Al-Mahani (full name Abu Abdollah Muhammad ibn Isa Mahani - in Arabic Al-Mahani). Conceived the idea of reducing geometrical problems such as duplicating the cube to problems in algebra.[70]
  • 828 - 896 [agriculture, astronomy, biology, botany, Earth sciences, meteorology] Al-Dinawari, the founder of Arabic botany, writes the Book of Plants, which describes at least 637 plants; discusses plant evolution from its birth to its death, describing the phases of plant growth and the production of flowers and fruit. He also deals with the applications of Islamic astronomy and meteorology to agriculture: he describes the astronomical and meteorological character of the sky, the planets and constellations, the sun and moon, the lunar phases indicating seasons and rain, the anwa (heavenly bodies of rain), and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes, wells and other sources of water. He also deals with the Earth sciences in the context of agriculture: he considers the Earth, stone and sands, and describes different types of ground, indicating which types are more convenient for plants and the qualities and properties of good ground.[73]
  • mid-800s - [chemistry] Al-Kindi writes on the distillation of wine as that of rose water and gives 107 recipes for perfumes, in his book Kitab Kimia al-`otoor wa al-tas`eedat (Book of the chemistry of perfumes and distillations).
  • 850/858 - 929 - [astronomy - mathematics] Al-Battani (Albatenius) writes works on astronomy and trigonometry. He is mentioned twenty-three times in Copernicus' work De revolutionibus orbium celestium (On the Revolution of Heavenly Spheres).[75]
  • 850 - 930 [mathematics] born Abu Kamil of Egypt (full name, Abu Kamil Shuja ibn Aslam ibn Muhammad ibn Shuja) Forms an important link in the development of algebra between al-Khwarizmi and al-Karaji. Despite not using symbols, but writing powers of x in words, he had begun to understand what we would write in symbols as .[70]
  • 864 - 930 - [chemistry, medicine] Al-Razi (Rhazes) wrote on Naft (naphta or petroleum) and its distillates in his book Kitab sirr al-asrar (Book of the secret of secrets). When choosing a site to build Baghdad's hospital, he hung pieces of fresh meat in different parts of the city. The location where the meat took the longest to rot was the one he chose for building the hospital. He advocated that patients not be told their real condition so that fear or despair do not affect the healing process. He wrote the earliest descriptions on alkali, caustic soda, glycerine, and he first described the modern formula for soap and invented the soap bar.[77] He also Gave descriptions of equipment, processes and methods in his book Kitab al-Asrar (Book of Secrets) in 925, and he was the first to clearly describe and differentiate between measles and smallpox. He was also a pioneer of chemotherapy[78] and antiseptics.[33]
  • 875 - [aviation, flight] Abbas Ibn Firnas made the first recorded attempt at controlled flight employing a glider .[69]

10th century

  • 865 - 925 [chemistry, medicine] Muhammad ibn Zakarīya Rāzi (Rhazes), in his Doubts about Galen, was the first to prove both Aristotle's theory of classical elements and Galen's theory of humorism wrong using an experimental method. He carried out an experiment which would upset these theories by inserting a liquid with a different temperature into a body resulting in an increase or decrease of bodily heat, which resembled the temperature of that particular fluid. Al-Razi noted particularly that a warm drink would heat up the body to a degree much higher than its own natural temperature, thus the drink would trigger a response from the body, rather than transferring only its own warmth or coldness to it. Al-Razi's chemical experiments further suggested other qualities of matter, such as "oiliness" and "sulfurousness", or inflammability and salinity, which were not readily explained by the traditional fire, water, earth and air division of elements.[93]
  • 858 - 1048 [astronomical instruments] The first reference to an "observation tube" is found in the work of Al-Battani, and the first exact description of the observation tube was given by al-Biruni, in a section of his work that is "dedicated to verifying the presence of the new crescent on the horizon." Though these early observation tubes did not have lenses, they "enabled an observer to focus on a part of the sky by eliminating light interference." These observation tubes were later adopted in Latin-speaking Europe, where they influenced the development of the telescope.[94]
  • 865 - 925 [chemical technology] Kerosene was produced from the distillation of petroleum and was first described by al-Razi (Rhazes) in Baghdad. In his Kitab al-Asrar (Book of Secrets), he described two methods for the production of kerosene. One method involved using clay as an absorbent, while the other method involved using ammonium chloride (sal ammoniac). Al-Razi also described the first kerosene lamps (naffatah) used for heating and lighting in his Kitab al-Asrar (Book of Secrets). These were used in the oil lamp industry.[95]
  • 900s - [mathematics, accounting] By this century, three systems of counting are used in the Arab world. Finger-reckoning arithmetic, with numerals written entirely in words, used by the business community; the sexagesimal system, a remnant originating with the Babylonians, with numerals denoted by letters of the arabic alphabet and used by Arab mathematicians in astronomical work; and the Hindu-Arabic numeral system, which was used with various sets of symbols.[70] Its arithmetic at first required the use of a dust board (a sort of handheld blackboard) because "the methods required moving the numbers around in the calculation and rubbing some out as the calculation proceeded." Al-Uqlidisi (born 920) modified these methods for pen and paper use.[70] Eventually the advances enabled by the decimal system led to its standard use throughout the region and the world.
  • 920 [mathematics] Born al-Uqlidisi. Modified arithmetic methods for the Indian numeral system to make it possible for pen and paper use. Until then, doing calculations with the Indian numerals necessitated the use of a dust board as noted earlier.
  • 936 - 1013 [medicine] Al-Zahrawi (Latinized name, Albucasis) Surgery, Medicine. Called the "Father of Modern Surgery."[74]
  • 940 - 997 [astronomy; mathematics] Muhammad Al-Buzjani. Mathematics, Astronomy, Geometry, Trigonometry.
  • 940 [mathematics] Born Abu'l-Wafa al-Buzjani. Wrote several treatises using the finger-counting system of arithmetic, and was also an expert on the Indian numerals system. About the Indian system he wrote: "[it] did not find application in business circles and among the population of the Eastern Caliphate for a long time."[70] Using the Indian numeral system, abu'l Wafa was able to extract roots.
  • 953 [mathematics] Born al-Karaji of Karaj and Baghdad (full name, Abu Bekr ibn Muhammad ibn al-Husayn Al-Karaji or al-Karkhi). Believed to be the "first person to completely free algebra from geometrical operations and to replace them with the arithmetical type of operations which are at the core of algebra today. He was first to define the monomials , , , ... and , , , ... and to give rules for products of any two of these. He started a school of algebra which flourished for several hundreds of years".[70] Discovered the binomial theorem for integer exponents. This "was a major factor in the development of numerical analysis based on the decimal system."[70]
  • 953 [technology] The earliest historical record of a reservoir fountain pen dates back to 953, when Ma'ād al-Mu'izz, the caliph of Egypt, demanded a pen which would not stain his hands or clothes, and was provided with a pen which held ink in a reservoir and delivered it to the nib via gravity and capillary action, as recorded by Qadi al-Nu'man al-Tamimi (d. 974) in his Kitdb al-Majalis wa'l-musayardt.[110][111]
  • 957 [geography; cartography; exploration; chemistry] died Abul Hasan Ali Al-Masudi, best known as a cartographer, was also a traveler historian, etc. Al-mas`oudi described his visit to the oilfields of Baku. Wrote on the reaction of alkali water with zaj (vitriol) water giving sulfuric acid.
  • 965 - 1040 [mathematics; optics; physics] Born ibn al-Haitham (full name, ; Latinized name, Alhazen). Possibly the first to classify all even perfect numbers (i.e., numbers equal to the sum of their proper divisors) as those of the form where is prime number.[70] Al-Haytham is also the first person to state Wilson's theorem. if is prime than is divisible by . "It is called Wilson's theorem because of a comment by Waring in 1770 that John Wilson had noticed the result. There is no evidence that Wilson knew how to prove it. It was over 750 years later that Lagrange gave the first known proof to the statement in 1771.![70] “Haytham in the tenth-eleventh century wrote a scathing critique of Ptolemy’s work: ‘Ptolemy assumed an arrangement that cannot exist, and the fact that this arrangement produces in his imagination the motions that belong to the planets does not free him from the error he committed in his assumed arrangement, for the existing motions of the planets cannot be the result of an arrangement that is impossible to exist’.”[112]
  • 980 [mathematics] Born al-Baghdadi (full name, ). Studied a slight variant of Thabit ibn Qurra's theorem on amicable numbers.[70] Al-Baghdadi also wrote texts comparing the three systems of counting and arithmetic used in the region during this period. Made improvements on the decimal system.
  • 981 - 1037 [astronomy; mathematics; medicine; philosophy] Ibn Sina (Avicenna); Medicine, Philosophy, Mathematics, Astronomy. Is considered to be the father of modern medicine

11th century

  • 1000s - [civil engineering] Cobwork (tabya) first appeared in the Maghreb and al-Andalus in the 11th century, and was later described in detail by Ibn Khaldun in the 14th century, who regarded it as a characteristically Muslim practice. Cobwork later spread to other parts of Europe from the 12th century onwards.[126]
  • 1000 - 1020 - [astronomy, engineering] Al-Sijzi invents the Zuraqi, a unique astrolabe designed for a heliocentric planetary model in which the Earth is moving rather than the sky.[129]
  • 1000 - 1048 - [earth sciences, Indology, geodesy, geology] Abū Rayhān al-Bīrūnī, who is considered the father of Indology, the father of geodesy, one of the first geologists, and an influential geographer, hypothesized that India was once covered by the Indian Ocean while observing rock formations at the mouths of rivers,[143] introduced techniques to measure the Earth and distances on it using triangulation, and measured the radius of the Earth as 6339.6 km, the most accurate up until the 16th century.[144] He also determines the Earth's circumference.
  • 1021 - 1037 - [optics, physics] Avicenna "observed that if the perception of light is due to the emission of some sort of particles by a luminous source, the speed of light must be finite."[164] He also provided a sophisticated explanation for the rainbow phenomenon.[165]
  • 1025 - [medicine, pathology] In The Canon of Medicine, Avicenna is the first to carry out cancer therapy. He recognized cancer as a tumor and noted that a "cancerous tumour progressively increases in size, is destructive and spreads roots which insinuate themselves amongst the tissue elements." He also attempted the earliest known treatments for cancer. One method he discovered was the "Hindiba", a herbal compound drug which Ibn al-Baitar later identified as having "anticancer" properties and which could also treat other tumors and neoplastic disorders.[178] After recognizing its usefulness in treating neoplastic disorders, Hindiba was patented in 1997 by Nil Sari, Hanzade Dogan, and John K. Snyder.[179] Another method for treating cancer first described by Avicenna was a surgical treatment. He stated that the excision should be radical and that all diseased tissue should be removed, which included the use of amputation or the removal of veins running in the direction of the tumor. He also recommended the use of cauterization for the area being treated if necessary.[124] Avicenna's Canon was also the first to describe the symptoms of esophageal cancer and the first to refer to it as "cancer of the esophagus."[180] Hirudotherapy, the use of medicinal leech for medical purposes, was also introduced by Avicenna in The Canon of Medicine. He considered the application of leech to be more useful than cupping in "letting off the blood from deeper parts of the body." He also introduced the use of leech as treatment for skin disease. Leech therapy became a popular method in medieval Europe due to the influence of his Canon.[181] In phytotherapy, Avicenna also introduced the medicinal use of Taxus baccata L. He named this herbal drug as "Zarnab" and used it as a cardiac remedy. This was the first known use of a calcium channel blocker drug, which were not used in the Western world until the 1960s.[182]
  • 1025 - 1028 - [astronomy] Ibn al-Haytham, in his Doubts on Ptolemy, criticizes Ptolemy's astronomical system for relating actual physical motions to imaginary mathematical points, lines, and circles.
  • 1029 - [chemistry, technology] The purification process for potassium nitrate (saltpetre; natrun or barud in Arabic) was first described by the Muslim chemist Ibn Bakhtawayh in his Al-Muqaddimat.[187]
  • 1030 - 1048 - [astronomy] Abu Said Sinjari suggested the possible heliocentric movement of the Earth around the Sun, which Abū al-Rayhān al-Bīrūnī did not reject.[189] Al-Biruni agreed with the Earth's rotation about its own axis, and while he was initially neutral regarding the heliocentric and geocentric models,[190] he considered heliocentrism to be a philosophical problem.[191] He remarked that if the Earth rotates on its axis and moves around the Sun, it would remain consistent with his astronomical parameters.[148]
  • 1031 - [astronomy] Abū al-Rayhān al-Bīrūnī completes his extensive astronomical encyclopaedia Canon Mas’udicus,[192] in which he records his astronomical findings and formulates astronomical tables. It presents a geocentric model, tabulating the distance of all the celestial spheres from the central Earth.[193] The book introduces the mathematical technique of analysing the acceleration of the planets, and first states that the motions of the solar apogee and the precession are not identical. Al-Biruni also discovered that the distance between the Earth and the Sun is larger than Ptolemy's estimate, on the basis that Ptolemy disregarded the annual solar eclipses. Al-Biruni also described the Earth's gravitation as "the attraction of all things towards the centre of the earth."[148]
  • 1038 - [astronomy] Ibn al-Haytham described the first non-Ptolemaic configuration in The Model of the Motions. His reform excluded cosmology, as he developed a systematic study of celestial kinematics that was completely geometric. This in turn led to innovative developments in infinitesimal geometry.[194] His reformed model was the first to reject the equant[195] and eccentrics,[196] free celestial kinematics from cosmology, and reduce physical entities to geometrical entities. The model also propounded the Earth's rotation about its axis,[197] and the centres of motion were geometrical points without any physical significance, like Johannes Kepler's model centuries later.[198]
  • 1044 or 1048 - 1123 [mathematics, literature] Omar Khayyám, a mathematician and poet, "gave a complete classification of cubic equations with geometric solutions found by means of intersecting conic sections. Khayyam also wrote that he hoped to give a full description of the algebraic solution of cubic equations in a later work: 'If the opportunity arises and I can succeed, I shall give all these fourteen forms with all their branches and cases, and how to distinguish whatever is possible or impossible so that a paper, containing elements which are greatly useful in this art will be prepared'."[70] He later became the first to find general geometric solutions of cubic equations and laid the foundations for the development of analytic geometry and non-Euclidean geometry. He extracted roots using the decimal system (Hindu-Arabic numeral system). He is well-known for his poetic work Rubaiyat of Omar Khayyam, but there is dispute whether the Maqamat, a famous diwan of poetry translated to English are actually his work.
  • 1070 - [astronomy] Abu Ubayd al-Juzjani proposed a non-Ptolemaic configuration in his Tarik al-Aflak. In his work, he indicated the so-called "equant" problem of the Ptolemic model, and proposed a solution for the problem.
  • 1085 - 1099 - [related] First wave of devastation of Muslim resources, lives, properties, institutions, and infrastructure over a period of one hundred years: Fall of Muslim Toledo (1085), Malta (1090), Sicily (1091) and Jerusalem (1099). This was followed by several Crusades from 1095 to 1291.
  • 1087 - [astronomy] Abū Ishāq Ibrāhīm al-Zarqālī publishes the Almanac of Azarqueil, the first almanac. The entries found in the almanac "give directly the positions of the celestial bodies and need no further computation". The work provided the true daily positions of the sun, moon and planets for four years from 1088 to 1092, as well as many other related tables. A Latin translation and adaptation of the work appeared as the Tables of Toledo in the 12th century and the Alfonsine tables in the 13th century.[200][201]

12th century

  • 1100 - 1138 - [astronomy] Ibn Bajjah (Avempace) develops the first planetary model without any epicycles, as an alternative to Ptolemy's model.
  • 1100 - 1166 [cartography, geography] Muhammad al-Idrisi, aka Idris al-Saqalli aka al-sharif al-idrissi of Andalusia and Sicily, also known as Dreses in Latin. Among his works are a world map and the first known globe. He is said to draw the first correct map of the world "lawh al-tarsim" (plank of drought). His maps were used extensively during the explorations of the era of European renaissance. Roger II of Sicily commemorated his world map on a circle of silver weighing about 400 pounds. Works include Nozhat al-mushtaq fi ikhtiraq al-&agrav;faq dedicated to Roger II of Sicily, which is a compendium of the geographic and sociologic knowledge of his time as well as descriptions of his own travels illustrated with over seventy maps; Kharitat al-`alam al-ma`mour min al-ard (Map of the inhabited regions of the earth) wherein he divided the world into 7 regions, the first extending from the equator to 23 degrees latitude, and the seventh being from 54 to 63 degrees followed by a region uninhabitable due to cold and snow.
  • 1115 - 1116 [astronomy, engineering] Al-Khazini wrote the Sinjaric Tables, in which he gave a description of his construction of a 24 hour water clock designed for astronomical purposes, an early example of an astronomical clock, and the positions of 46 stars computed for the year 500 AH (1115-1116 CE). He also computed tables for the observation of celestial bodies at the latitude of Merv.[218][219][220] The Sinjaric Tables was later translated into Greek by Gregory Choniades in the 13th century and was studied in the Byzantine Empire.[221]
  • 1118 - 1174 - [education, medicine] Al-Nuri hospital in Egypt was a famous teaching hospital built by Nur ad-Din Zanqi, and was where many renowned physicians were taught. The hospital's medical school is said had elegant rooms, and a library which many of its books were donated by Zangi's physician, Abu al-Majid al-Bahili.[224]
  • 1126 - 1198 - [mechanics, physics] Averroes (Ibn Rushd) is the first to define and measure force as "the rate at which work is done in changing the kinetic condition of a material body"[228] and the first to correctly argue "that the effect and measure of force is change in the kinetic condition of a materially resistant mass."[229]
  • 1130 - [mathematics] Born al-Samawal. An important member of al-Karaji's school of algebra. Gave this definition of algebra: "[it is concerned] with operating on unknowns using all the arithmetical tools, in the same way as the arithmetician operates on the known."[70]
  • 1135 - [mathematics] Born Sharafeddin Tusi. Follows al-Khayyam's application of algebra of geometry, rather than follow the general development that came through al-Karaji's school of algebra. Wrote a treatise on cubic equations which "represents an essential contribution to another algebra which aimed to study curves by means of equations, thus inaugurating the beginning of algebraic geometry."[72][70]

13th century

  • 1200s - [chemistry] Al-Jawbari describes the preparation of rose water in the Book of Selected Disclosure of Secrets (Kitab kashf al-Asrar).
  • 1200s - [chemistry; materials, glassmaking] Arabic manuscript on the manufacture of false gemstones and diamonds. Also describes spirits of alum, spirits of saltpetre and spirits of salts (hydrochloric acid).
  • 1204 - [astronomy] Died, Al-Bitruji (Alpetragius.)
  • 1207 - 1273 [sociology; poetry; spirituality] Jalal al-Din Muhammad Rumi, one of the best known Persian passion poets, famous for poignant poetry on the theme of spiritual enlightenment and passion.
  • 1217 - 1329 [related] "Second wave of devastation of Muslim resources, lives, properties, institutions, and infrastructure over a period of one hundred and twelve years. Crusader invasions (1217-1291) and Mongol invasions (1219-1329). Crusaders active throughout the Mediterranean from Jerusalem and west to Muslim Spain. Fall of Muslim Córdoba (1236), Valencia (1238) and Seville (1248). Mongols devastation from the eastern most Muslim frontier, Central and Western Asia, India, Persia to Arab heartland. Fall of Baghdad (1258) and the end of Abbasid Caliphate. Two million Muslims massacred in Baghdad. Major scientific institutions, laboratories, and infrastructure destroyed in leading Muslim centers of civilization."
  • 1242 - 1244 [biology, medicine, surgery, urology, scientific method] Ibn al-Nafis publishes the first 43 volumes of his medical encyclopedia, The Comprehensive Book on Medicine. One volume is dedicated to surgery, where he describes the "general and absolute principles of surgery", a variety of surgical instruments, and the examination of every type of surgical operation known to him. He states that in order for a surgical operation to be successful, full attention needs to be given to three stages of the operation: the "time of presentation" when the surgeon carries out a diagnosis on the affected area, the "time of operative treatment" when the surgeon repairs the affected organs, and the "time of preservation" when the patient needs to be taken care of by nurses. The Comprehensive Book on Medicine was also the earliest book dealing with the decubitus of a patient.[257] The Comprehensive Book on Medicine is also the earliest book dealing with the decubitus of a patient.[258] Another section is dedicated to urology, including the issues of sexual dysfunction and erectile dysfunction, where Ibn al-Nafis is one of the first to prescribe clinically tested drugs as medication for the treatment of these problems. His treatments are mainly oral drugs, though early topical and transurethral treatments are also mentioned in a few cases.[92]
  • 1244 - 1288 [medicine] Ibn al-Nafis writes down notes for upcoming volumes of his medical encyclopedia, The Comprehensive Book on Medicine. His notes add up to a total of 300 volumes in length, though he is only able to publish 80 volumes before he dies in 1288.[259] Even in its incomplete state, however, The Comprehensive Book on Medicine is one of the largest known medical encyclopedias in history, and was much larger than the more famous The Canon of Medicine by Avicenna. However, only several volumes of The Comprehensive Book on Medicine have survived into modern times.[260]
  • 1244 - 1288 [anatomy, medicine, science of hadith] Ibn al-Nafis publishes many other works, including The Choice of Foodstuffs which places a greater emphasis on diet and nutrition rather than the prescriptions of drugs; Commentary on Hippocrates' Aphorisms where he expresses his rebellious nature against established authorities as he states that he has decided to "throw light on and stand by true opinions, and forsake those which are false and erase their traces";[261] A Short Account of the Methodology of Hadith on the science of hadith; Epitome of the Canon; Synopsis of Medicine; An Essay on Organs; Reference Book for Physicians; among many others.
  • 1248 - [anatomy, botany, pharmacy, veterinary medicine] Ibn al-Baitar dies. He studied and wrote on botany, pharmacy and is best known for studying animal anatomy and medicine. The Arabic term for veterinary medicine is named after him.
  • 1258 - The sack of Baghdad results in the destruction of Baghdad along with all its libraries, including the House of Wisdom. Survivors said that the waters of the Tigris ran black with ink from the enormous quantities of books flung into the river.
  • 1260 - [chemistry, military technology] The first portable hand cannons (midfa) loaded with explosive gunpowder, the first example of a handgun and portable firearm, were used by the Egyptians to repel the Mongols at the Battle of Ain Jalut. The gunpowder compositions used for the cannons at these battles were later described in several manuscripts in the early 14th century. According to Shams al-Din Muhammad (d. 1327), the cannons had an explosive gunpowder composition (74% saltpetre, 11% sulfur, 15% carbon) almost identical to the ideal compositions for explosive gunpowder used in modern times. Gunpowder cartridges were also first employed at the Battle of Ain Jalut by the Egyptians, for use in their fire lances and hand cannons against the Mongols. Egyptian soldiers at the Battle of Ain Jalut were also the first to smear dissolved talc (from Arabic talq) on their hands, as forms of fire protection from gunpowder. They also wore fireproof clothing, to which gunpowder cartridges were attached.[187]
  • 1270 - [chemistry, military technology] The first complete purification process for potassium nitrate is described in 1270 by the Arab chemist and engineer Hasan al-Rammah of Syria in his book al-Furusiyya wa al-Manasib al-Harbiyya (The Book of Military Horsemanship and Ingenious War Devices, a.k.a. the Treatise on Horsemanship and Stratagems of War). He first described the use of potassium carbonate (in the form of wood ashes) to remove calcium and magnesium salts from the potassium nitrate.[264][187] Several almost identical compositions were first described by the Arab engineer Hasan al-Rammah as a recipe for the rockets (tayyar) he described in The Book of Military Horsemanship and Ingenious War Devices in 1270. Several examples include a tayyar "rocket" (75% saltpetre, 8% sulfur, 15% carbon) and the tayyar buruq "lightning rocket" (74% saltpetre, 10% sulfur, 15% carbon). He also states recipes for fireworks and firecrackers made from these explosive gunpowder compositions. He states in his book that many of these recipes were known to his father and grandfather, hence dating back to at least the late 12th century. Compositions for an explosive gunpowder effect were not known in China or Europe until the 14th century.[28][187] The torpedo is also invented by Hasan al-Rammah, who shows illustrations of a torpedo running on water with a rocket system filled with explosive materials and having three firing points.[204]
  • 1271 - 1273 - Ballistic weapons were manufactured in the Muslim world since the time of Kublai Khan in the 13th century. According to Chinese sources, two Muslim engineers, Alaaddin and Ismail (d. 1330), built machines of a ballistic-weapons nature before the besieged city of Hang-show between 1271-1273. Alaaddin's weapons also played a major role in the conquest of several other Chinese cities. His son Ma-ho-scha also developed ballistic weapons. Ismail (transliterated as I-ssu-ma-yin) was present in the Mongol siege of Hsiang-yiang, where he built a war machine with the characteristics of a ballistic weapon. Chinese sources mention that when this war machines were fired, the earth and skies shook, the cannons were buried seven feet into the ground and destroyed everything. His son Yakub also developed ballistic war machines.[204]
  • 1273 - 1331 [astronomy; geography; history] Abu al-Fida (Abulfeda).
  • 1275 - [engineering, rocketry, weaponry] Hasan al-Rammah invents the torpedo in Syria.[265]
  • 1277 - [materials; glass and ceramics] A treaty for the transfer of glassmaking technology signed between the crusader Bohemond VII, titular prince of Antioch and the Doge of Venice leads to the transfer of Syrian glassworkers and their trade secrets and the subsequent rise of Venetian glass industry, the most prominent in Europe for centuries. The techniques henceforth, closely guarded by Venitians only become known in France in the 1600s.
  • c. 1296 - [astronomy, technology] The first astronomical uses of the magnetic compass is found in a treatise on astronomical instruments written by the Yemeni sultan al-Ashraf (d. 1296). This was the first reference to the compass in astronomical literature.[267]

14th century

  • 1300 - 1348 [navigation] Abubakari II, a mansa of the Mali Empire, attempts to cross the Atlantic Ocean. According to the Arabic historian Ibn Fadlullah al-Umari (1300-1348), in his encyclopaedic work Masalik Al-Absar, Abubakari set out on a journey equipped with "two hundred boats full of men, and many others full of gold, water and provisions sufficient for several years" (see Pre-Columbian Andalusian-Americas contact theories).
  • 1301 - [ceramics] Al-Kashani promotes a center for ceramics. He also writes a book on Islamic ceramics techniques. His name is still associated with ceramics in the Muslim Orient today.
  • 1312 - 1361 [cryptography] Taj ad-Din Ali ibn ad-Duraihim ben Muhammad ath-Tha 'alibi al-Mausili wrote on cryptology, but his writings have been lost. To his work is attributed the section on cryptology in an encyclopedia (Subh al-a 'sha) by Shihab al-Din abu 'l-Abbas Ahmad ben Ali ben Ahmad Abd Allah al-Qalqashandi (1355 or 1356 – 1418). The list of ciphers in this work included both substitution and transposition, and for the first time, a cipher with multiple substitutions for each plaintext letter. Also traced to Ibn al-Duraihim is an exposition on and worked example of cryptanalysis, including the use of tables of letter frequencies and sets of letters which can not occur together in one word. Al-Qalqashandi was a medieval Egyptian writer born in a village in the Nile Delta. He is the author of Subh al-a 'sha, a fourteen volume encyclopedia in Arabic, which included a section on cryptology. This information was attributed to Taj ad-Din al-Mausili (see Ahmad al-Qalqashandi).
  • 1313 - 1374 - [bacteriology, etiology, medicine, pathology] The Andalusian physician Ibn al-Khatib wrote a treatise called On the Plague, in which he stated: "The existence of contagion is established by experience, investigation, the evidence of the senses and trustworthy reports. These facts constitute a sound argument. The fact of infection becomes clear to the investigator who notices how he who establishes contact with the aflicted gets the disease, whereas he who is not in contact remains safe, and how transmission is affected through garments, vessels and earrings."[270]
  • 1304 – 1375 [astronomy] Ibn al-Shatir, a Muslim astronomer from Damascus, in A Final Inquiry Concerning the Rectification of Planetary Theory, incorporated the Urdi lemma and eliminated the need for an equant by introducing an extra epicycle (the Tusi-couple), departing from the Ptolemaic system in a way that was mathematically identical to what Nicolaus Copernicus did in the 16th century. Ibn al-Shatir's system was also only approximately geocentric, rather than exactly so, having demonstrated trigonometrically that the Earth was not the exact center of the universe. While previous Maragha models were just as accurate as the Ptolemaic model, Ibn al-Shatir's geometrical model was the first that was actually superior to the Ptolemaic model in terms of its better agreement with empirical observations.[271][272] Ibn al-Shatir’s rectified model was later adapted into a heliocentric model by Copernicus,[273] which was mathematically achieved by reversing the direction of the last vector connecting the Earth to the Sun in Ibn al-Shatir's model.[274]
  • 1371 [astronomy, engineering] As ancient sundials were nodus-based with straight hour-lines, they indicated unequal hours—also called temporary hours—that varied with the seasons. Every day was divided into twelve equal segments; thus, hours were shorter in winter and longer in summer. The idea of using hours of equal length throughout the year was the innovation of Ibn al-Shatir, based on earlier developments in trigonometry by Muhammad ibn Jābir al-Harrānī al-Battānī (Albategni). Ibn al-Shatir was aware that "using a gnomon that is parallel to the Earth's axis will produce sundials whose hour lines indicate equal hours on any day of the year." His sundial is the oldest polar-axis sundial still in existence. The concept later appeared in Western sundials from at least 1446.[275][276]
  • 1380 [mathematics] Al-Kashi "contributed to the development of decimal fractions not only for approximating algebraic numbers, but also for real numbers such as pi. His contribution to decimal fractions is so major that for many years he was considered as their inventor. Although not the first to do so, al-Kashi gave an algorithm for calculating nth roots which is a special case of the methods given many centuries later by Ruffini and Horner."[70]

15th century

  • 1400 - 1500 - [related] Third wave of devastation of Muslim resources, lives, properties, institutions, and infrastructure. End of Muslim rule in Spain after the completion of the Reconquista in 1492. More than one million volumes of Muslim works on science, arts, philosophy and culture were burnt in the public square of Vivarrambla in Granada. Colonization began in Africa, Asia, and the Americas.[287]
  • 1400s [mathematics] Ibn al-Banna and al-Qalasadi used symbols for mathematics in the 15th century "and, although we do not know exactly when their use began, we know that symbols were used at least a century before this."[70]
  • 1400 - 1429 [astronomy, mathematics] Jamshīd al-Kāshī is the first to use the decimal point notation in arithmetic and Arabic numerals. His works include The Key of arithmetics, Discoveries in mathematics, The Decimal point, and The benefits of the zero. The contents of the Benefits of the Zero are an introduction followed by five essays: "On whole number arithmetic", "On fractional arithmetic", "On astrology", "On areas", and "On finding the unknowns [unknown variables]". He also wrote the Thesis on the sine and the chord; The garden of gardens or Promenade of the gardens describing an instrument he devised and used at the Samarqand observatory to compile an ephemeris and for computing solar and lunar eclipses; the ephemeresis Zayj Al-Khaqani which also includes mathematical tables and corrections of the ephemeresis by al-Tusi; Thesis on finding the first degree sine; and more.
  • 1400 - 1474 [astronomy, astrophysics, mathematics, physics] Ali al-Qushji (d. 1474) rejected Aristotelian physics and completely separated natural philosophy from Islamic astronomy, allowing astronomy to become a purely empirical and mathematical science. This allowed him to explore alternatives to the Aristotelian notion of a stationery Earth, as he explored the idea of a moving Earth instead. He found empirical evidence for the Earth's rotation through his observation on comets and concluded, on the basis of empiricism rather than speculative philosophy, that the moving Earth theory is just as likely to be true as the stationary Earth theory.[292][293][294] Ali al-Qushji also improved on Nasir al-Din al-Tusi's planetary model and presented an alternative planetary model for Mercury.[295]
  • 1411 [mathematics] Al-Kashi writes Compendium of the Science of Astronomy.[296]
  • 1424 [mathematics] Al-Kashi writes Treatise on the Circumference giving a remarkably accurate approximation to pi in both sexagesimal and decimal forms, computing pi to 8 sexagesimal places and 16 decimal places.[296]
  • 1427 [mathematics] Al-Kashi completes The Key to Arithmetic containing work of great depth on decimal fractions. It applies arithmetical and algebraic methods to the solution of various problems, including several geometric ones and is one of the best textbooks in the whole of medieval literature.[296]

16th century

  • 1500s [architecture, engineering, urban planning] The city of Shibam is built in Yemen. This city is regarded as the "oldest skyscraper-city in the world", the "Manhattan of the desert", and the earliest example of urban planning based on the principle of vertical construction. Shibam was made up of over 500 tower houses, each one rising 5 to 9 storeys high, with each floor being an apartment occupied by a single family.[297] The city has the tallest mudbrick buildings in the world, with some of them being over 100 feet[298] (over 30 meters) high, thus being the first high-rise (which need to be at least 75 feet or 23 meters) apartment buildings and tower blocks.
  • 1500 - 1528 [astronomy, astrophysics, physics] Al-Birjandi continued the debate on the Earth's rotation after Ali al-Qushji. In his analysis of what might occur if the Earth were rotating, he develops a hypothesis similar to Galileo Galilei's notion of "circular inertia",[299] which he described in an observational test (as a response to one of Qutb al-Din al-Shirazi's arguments): "The small or large rock will fall to the Earth along the path of a line that is perpendicular to the plane (sath) of the horizon; this is witnessed by experience (tajriba). And this perpendicular is away from the tangent point of the Earth’s sphere and the plane of the perceived (hissi) horizon. This point moves with the motion of the Earth and thus there will be no difference in place of fall of the two rocks."[300]
  • 1500 - 1550 [astronomy] Shams al-Din al-Khafri, the last major astronomer of the hay'a tradition, was the first to realize that "all mathematical modeling had no physical truth by itself and was simply another language with which one could describe the physical observed reality."[301]
  • 1577 - 1580 [astronomy, engineering] At the Istanbul observatory of al-Din, Taqi al-Din carries out astronomical observations. He produces a zij (named Unbored Pearl) and astronomical catalogues that are more accurate than those of his contemporaries, Tycho Brahe and Nicolaus Copernicus. Taqi al-Din is able to achieve this with his new invention of the "observational clock", which he describes as "a mechanical clock with three dials which show the hours, the minutes, and the seconds." This is the first clock to measure time in seconds, and he uses it for astronomical purposes, specifically for measuring the right ascension of the stars. This is considered one of the most important innovations in 16th century practical astronomy, as previous clocks were not accurate enough to be used for astronomical purposes.[305] He further improves his observational clock, using only one dial to represent the hours, minutes and seconds, describing it as "a mechanical clock with a dial showing the hours, minutes and seconds and we divided every minute into five seconds."[306] Taqi al-Din is also the first astronomer to employ a decimal point notation in his observations rather than the sexagesimal fractions used by his contemporaries and predecessors.[305]
  • 1589 - 1590 [astronomy, engineering, metallurgy] The seamless celestial globe invented by Muslim metallurgists and instrument-makers in Mughal India, specifically Lahore and Kashmir, is considered to be one of the most remarkable feats in metallurgy and engineering. All globes before and after this were seamed, and in the 20th century, it was believed by metallurgists to be technically impossible to create a metal globe without any seams. It was in the 1980s, however, that Emilie Savage-Smith discovered several celestial globes without any seams in Lahore and Kashmir. The earliest was invented in Kashmir by the Muslim metallurgist Ali Kashmiri ibn Luqman in 998 AH (1589-1590 CE) during Akbar the Great's reign; he invented the method of lost-wax casting in order to produce these globes. 21 such globes were produced, and these remain the only examples of seamless metal globes. These seamless celestial globes are considered to be an unsurpassed feat in metallurgy, hence some consider this achievement to be comparable to that of the Great Pyramid of Giza which was considered an unsurpassed feat in architecture until the 19th century.[310]

17th century

Sail plan for a polacca-xebec, first built by the Barbary pirates around the 16th and 17th centuries.
  • 1600s [transport, engineering] The Xebec and Polacca (Polacre) sailing ships used around the Mediterranean Sea from the 16th to the 19th centuries originated from the Barbary pirates, who successfully used them for naval warfare against European ships at the time. A combination of the fore and aft sails and aerodynamics, along with the improved square sail on the Polacca, allowed these ships to sail much closer to the wind than European and American ships. An expert on the Barbary pirates said that their ships had guns at the bow and stern. “They would approach, pounding away, and it took too long for our square riggers to bring the broadside guns around. The Arabs had oars and a sail arrangement that meant they were able to turn more quickly and could flee closer to the wind than we could chase them."[311]
  • 1600s [astronomy, engineering] Cartographic Qibla indicators were brass instruments with Mecca-centred world maps and cartographic grids engraved on them. They were invented in 17th-century Iran.[97] The cartographic Qibla indicator with sundial and compass was a Qibla instrument with a sundial and compass attached to it,[313] and was invented by Muhammad Husayn in the 17th century.[314]
  • 1633 [aviation, flight, rocketry] Hezarfen Ahmet Celebi's brother, Lagari Hasan Çelebi, launched himself in the first artificially-powered manned rocket, using 150 okka (about 300 pounds) of gunpowder as the firing fuel, and he landed successfully. According to Evliya Çelebi in the early 17th century, Lagari Hasan Çelebi launched himself in the air in a seven-winged rocket, which was composed of a large cage with a conical top filled with gunpowder. The flight was accomplished as a part of celebrations performed for the birth of Ottoman Emperor Murad IV's daughter in 1633. Evliya reported that Lagari made a soft landing in the Bosporus by using the wings attached to his body as a parachute after the gunpowder was consumed, foreshadowing the sea-landing methods of astronauts with parachutes after their voyages into outer space. Lagari's flight was estimated to have lasted about twenty seconds and the maximum height reached was around 300 metres (980 ft). This was the first known example of a manned rocket and an artificially-powered aircraft.[204] This is more than two hundred years before similar attempts in modern Europe and the United States.
  • 1659 - 1660 A seamless celestial globe is produced using a new lost-wax casting method in the Mughal Empire in 1070 AH (1659-60 CE) by Muhammad Salih Tahtawi with Arabic and Sanskrit inscriptions. Twenty other such globes were produced in Lahore and Kashmir during the Mughal Empire. They are considered one of the most remarkable feats in metallurgy. Before they were rediscovered in the 1980s, it was believed by modern metallurgists to be technically impossible to produce metal globes without any seams, even with modern technology.[317][310]

18th century

Tipu Sultan invented the first iron-cased and metal-cylinder rocket artillery in Mysore, India, alongside his father Hyder Ali, in the 1780s.
  • 1720 - [navigation technology] The Ottoman dockyard architect Ibrahim Efendi invented a submarine called the tahtelbahir. The Ottoman writer Seyyid Vehbi, in his Surname-i-Humayun, compared this submarine to an alligator. He recorded that during the circumcision ceremony for Sultan Ahmed III's sons, "the alligator-like submarine slowly emerged on the water and moved slowly to the sultan, and after staying on the sea for half an hour, submerged in the sea again to the great surprise of the public; then emerged one hour later, with five people walking outside the mouth of this alligator-like submarine, with trays of rice and zerde (a dish of sweetened rice) on their heads." He explained the technical information concerning the submarine "submerging in the sea and the crew being able to breath through pipes while under the sea".[204]
  • 1783 - 1799 - [rocketry] Tipu, Sultan of Mysore (r. 1783-1799) in the south of India, was an experimenter with war rockets and the inventor of iron-cased and metal-cylinder rocket artillery. He successfully used these iron rockets against the larger forces of the British East India Company during the Anglo-Mysore Wars. His rockets were much more advanced than what the British had seen, chiefly because of the use of iron tubes for holding the propellant; this enabled higher thrust and longer range for the missile (up to 2 km range). After Tipu's eventual defeat in the Fourth Anglo-Mysore War and the capture of the Mysore iron rockets, they were influential in British rocket development and were soon put into use in the Napoleonic Wars.[318] Two of his rockets, captured by the British at Srirangapatna, are displayed in the Woolwich Royal Artillery Museum in London. They were the first rockets to have a rocket motor casing made of steel with multiple nozzles. The rocket, 50 mm in diameter and 250 mm long, had a range performance of 900 meters to 1.5 km.[319] According to Stephen Oliver Fought and John F. Guilmartin, Jr. in Encyclopedia Britannica (2008): "Hyder Ali, prince of Mysore, developed war rockets with an important change: the use of metal cylinders to contain the combustion powder. Although the hammered soft iron he used was crude, the bursting strength of the container of black powder was much higher than the earlier paper construction. Thus a greater internal pressure was possible, with a resultant greater thrust of the propulsive jet. The rocket body was lashed with leather thongs to a long bamboo stick. Range was perhaps up to three-quarters of a mile (more than a kilometre). Although individually these rockets were not accurate, dispersion error became less important when large numbers were fired rapidly in mass attacks. They were particularly effective against cavalry and were hurled into the air, after lighting, or skimmed along the hard dry ground. Hyder Ali's son, Tippu Sultan, continued to develop and expand the use of rocket weapons, reportedly increasing the number of rocket troops from 1,200 to a corps of 5,000. In battles at Seringapatam in 1792 and 1799 these rockets were used with considerable effect against the British."[320]

19th century

  • 1814 - [cosmetics, hygiene] - The earliest documented evidence of shampoo dates back to the Bengali Muslim entrepreneur Sake Dean Mahomet, inspired by the Indian practice of making fragrant hair-oil. He opened the first shampooing bath known as 'Mahomed's Indian Vapour Baths' in Brighton, England, in 1759. His baths were like Turkish baths where clients received an Indian treatment of champi (shampooing) or therapeutic massage. His service was appreciated; he received the high accolade of being appointed ‘Shampooing Surgeon’ to both George IV and William IV.[22]

20th century
