Mathias de l'Obel, Mathias de Lobel or Matthaeus Lobelius (1538 – 3 March 1616) was a Flemish physician and botanist who was born in Lille, Flanders, in what is now Nord-Pas de Calais, France, and died at Highgate, London, England. Graduating in medicine from the University of Montpellier in 1565 he practiced medicine in the low countries and England, including positions as personal physicians to two monarchs. A member of the sixteenth century Flemish School of Botany, he wrote a series of major treatises on plants in both Latin and Dutch. He was the first botanist to appreciate the distinction between monocotyledons and dicotyledons. The Lobelia plant is named after him.

Mathias de l'Obel was born in Lille (Flemish Rijsel) in the County of Flanders, Spanish Netherlands, now French Flanders in 1538, the son of Jean De l'Obel, a lawyer whose practice specialized in aristocrats in the army. Relatively little is known about his life. By the age of sixteen he had already developed an interest in both botany and medicine. He spent some time traveling and studying in Italy in 1551 and 1563–1564 before studying medicine in Leuven and at Montpellier in France. He sought out Montpellier due to the reputation of Guillaume Rondolet, as had his earlier contemporary, Carolus Clusius. It is said that l'Obel was Rondolet's favourite pupil, and on his death in 1566 l'Obel inherited all his manuscripts. His botanical field work was under the supervision of Rondolet's son-in-law, Jacques Salomon d'Assas. He graduated with a medical degree on 22 March 1565, at the age of twenty-seven. He remained in Montpellier for a further two years, furthering his studies, including botanical expeditions in the Languedoc region.
He then spent some time traveling and settled in Elizabethan England for about four years (1566–1571), together with his fellow student Pierre Pena (1535–1605), probably as a protestant refugee.[a] He lived on Lime Street, London in any area containing many protestant refugees from the continent ("come for religion"), among fellow Flemings like James Garrett the apothecary. There he also came to know the English botanist, John Gerard. He and Pena brought with them their botanical collection and carried out botanical exploration in England before returning to the low countries sometime between 1571 and 1574.
l'Obel married Isabeau Laigniez (1576-1642) in Lille in 1596. Of their children, one daughter, Mary l'Obel, married Louis Le Myre (Ludovicus Myreus), who collaborated with him, the other, Anne l'Obel married Wolfgang Rumler. Both sons in law, le Myre and Rumler were pharmacists, with good reputations in London society. He eventually moved permanently to England in 1596. Among the English botanists, his closest friend was Thomas Penny, whom he had first met in Montpellier, and to whom he pays tribute in his dedication of the Stirpium adversaria (1571). l'Obel died in Highgate in 1616 at the age of 78, and was buried in the churchyard of St Denis.
Following his studies in Montpellier l'Obel set up a medical practice in England (1566–1571), living initially in London, and then in Somerset, near Bristol at the home of his patron, Edward St. Loo. There he was joined in botanical expeditions by Clusius. On his return to continental Europe, he practised in Antwerp (1571–1581) and then Delft (1581–1584). This period from 1571 to 1596, prior to his return to England was one of the most productive in his life, with two major publications. Delft had been the residence of William, Prince of Orange (William the Silent) since 1572, and became the capital of the newly independent Netherlands in 1581. In Delft l'Obel served as personal physician (hofarts) to the Protestant Prince William. The exact date of this appointment is uncertain, but his Kruydtboeck (1581) is dedicated to the Prince, and the title page describes l'Obel as Medecijn der Princ. suggesting it was some time between returning to the low countries in 1571 and 1581. His name also appears on a list of court personnel dated 1578. William. however, was assassinated in 1584. Claims that after William's death, l'Obel was employed by the Estates General, the governing body of the Netherlands, have been disputed. Following the assassination l'Obel became a city physician in Middelburg, which was then a prosperous centre of trade and capital of the province of Zeeland. He was responsible for the establishment of a botanical herb garden there, and would have known Ambrosius Bosschaert (1573–1621), the artist, best known for his meticulous flower paintings. Bosschaert was a member and eventually dean of the Saint Luke’s Guild in Middelburg.
In 1596 he moved from Middelburg, returning once more to England, becoming personal physician and botanicus regius (Botanist Royal) to King James I of England in 1607. From there he periodically returned to Middelburg for a visit. Amongst his responsibilities in England was as superintendent of the botanical garden of Lord Zouch in Hackney, a partnership brought about by Clusius. This was a physic garden and at the time, one of the few in existence in England. It became a gathering place for botanists, enabling l'Obel to become an important link between England and the continent. He also accompanied Lord Zouch on his posting as ambassador to Denmark in 1598, where he carried out botanical exploration. The latter was published in 1605 as an appendix to the second edition of Stirpium adversaria. It was through Zouch that he obtained the post of botanicus regius.
In 1597 he became involved in a controversy surrounding his friend John Gerard. In 1596 he had provided a preface to Gerard's Catalogus.[b] The following year, Gerard was working on a translation of Dodoens's Stirpium historiae pemptades sex (1583), to be published by John Norton, the Queen's Printer. James Garrett, on a visit to the Norton's publishing house, saw the proofs and alerted Norton as to both errors and unattributed borrowings from Lobelius. Norton then hired Lobelius as an expert editor, but when Gerard discovered this he had Lobelius dismissed, and had the work published under his own name as The Herball or Generall Historie of Plantes (1597). Lobelius provides an account of this in his Stirpium illustrationes (1655) in which he accuses Gerard of plagiarism.
He spent much of his life looking for a rational way to classify plants that could be tested by empiricism.
Sic enim ordine, quo nihil pulchrius in coelo, aut in Sapientis animo
An order, than which nothing more beautiful exists in the heavens, or in the mind of a wise man
In the Stirpium of 1571, it is the form of the leaves and their venation that he favoured. In doing so he distinguished between grass-like plants with long straight parallel veins, while the majority had broad leaves with net-like venation. In doing so he was the first to recognise the fundamental difference between monocotyledons (grass-like) and dicotyledons, although he never suggested names to group these plants under.
Life and times
Lobelius has been described as the least well known of a group variously called the Ecole flamande de Botanique du XVIme siècle (16th century Flemish school of botany) or Flemish "Fathers of Botany",[d] which, in addition to Lobelius, included Carolus Clusius and Rembert Dodoens. Lobelius[e] and others have stated that the collection and cultivation of plants had been a preoccupation in the Southern Netherland (Flanders or Galliae Belgicae) since the crusades, and that Flemish gardens contained many rare plants, although these were destroyed in the civil wars of the sixteenth century, and he mentions many important growers such as Carolus de Croy, and his wife Marie de Brimeu, Joannes de Brancion and Joannes van der Dilf.
At the opening of the sixteenth century the general belief was that the plant world had been completely described by Dioscorides, in his De Materia Medica. During Lobelius' lifetime, botanical knowledge was undergoing enormous expansion, partly fueled by the expansion of the known plant world by New World exploration, the discovery of printing and the use of wood-block illustration. This period is thought of as a botanical Renaissance. Europe became engrossed with natural history from the 1530s, and gardening and cultivation of plants became a passion and prestigious pursuit from monarchs to universities. The first botanical gardens appeared as well as the first illustrated botanical encyclopaedias, together with thousands of watercolours and woodcuts. The experience of farmers, gardeners, foresters, apothecaries and physicians was being supplemented by the rise of the plant expert. Collecting became a discipline, specifically the Kunst- und Wunderkammern (cabinets of curiosities) outside of Italy and the study of naturalia became widespread through many social strata. The great botanists of the sixteenth century were all, like Lobelius, originally trained as physicians, who pursued a knowledge of plants not just for medicinal properties, but in their own right. Chairs in botany, within medical faculties were being established in European universities throughout the sixteenth century in reaction to this trend, and the scientific approach of observation, documentation and experimentation was being applied to the study of plants.
These were also turbulent times. Following the protestant reformation in the mid sixteenth century, and the subsequent counter-reformation there was much religious intolerance and persecution, while in the Netherlands the northern provinces started a rebellion against the governing Spaniards, the Eighty Years War (1568–1648). As a result many people fled or emigrated and many herbal and botanical gardens were destroyed. Lobelius stated that it was becoming increasingly difficult to live in his native Flanders.
Stirpium adversaria nova (1570-1)
Lobelius' first publication, Stirpium adversaria nova (1571) was written at the end of his stay in England, published in London and dedicated to Elizabeth I. It was written in collaboration with Pierre Pena (Petrus Pena), his fellow student and traveling companion from Provence, and was an important milestone in botanical history, placing emphasis on medicine and botany as sciences that must be based on thorough and exact observation. The extent of Pena's contribution is unknown, although his name appears first on the title page (see illustration). Like his contemporaries, l'Obel's interest in plants was driven by their pharmacological properties. The Stirpium was l'Obel's major botanical work and included information on about 1,200–1,300 plants that they had collected in the area around Montpellier, in the Cévennes, in the Low Countries, and in England, and included additional information on cultivation and the manufacture of plant products, such as beer. This was one of the earliest attempts to classify plants according to their natural affinities, rather than their medical uses. L'Obel based this on the form of their leaves. His concepts of genus and family formed the basis of later more definitive classifications such as that of Linnaeus, and some of his groupings have survived into modern times. Although it was eventually to be the work on which l'Obel's reputation would rest, based on the system of classification that he set out, at the time of its publication, it met with only moderate success and much criticism.
Plantarum seu stirpium historia (1576)
The Stirpium adversaria was followed five years later by Plantarum seu stirpium historia (1576). This was a two volume publication consisting of a new work, the Stirpium observationes together with a re-issue of the Stirpium adversaria, titled Nova stirpium adversaria as a companion piece, together with a treatise on herbal remedies by Rondelet and a multilingual index to the composite work. It included 1,486 engravings of plants, including those from works by Pietro Mattioli, Rembert Dodoens, and Charles de l’Écluse. In 1581 he produced his Kruydtboeck, a Dutch translation of the former work. This was well received and considered a milestone in plant systematics. Lobelius' hometown of Lille sent him a gift of 50 pounds in recognition of the importance of the work.
In 1605 he reissued the Stirpium, including in it an essay on the pharmacological studies of his mentor, Guillaume Rondolet, the Pharmacopoeia Rondelletii. At the time of his death in 1616, his Stirpium illustrationes was unpublished, and was not published till 1655 (in part) by William How. In the meantime, John Parkinson had used it in his Theatrum botanicum (1640).
A further publication, the Stirpium seu Plantarum Icones (1581) in the form of a Flora was for a long time attributed to l'Obel, despite his name not appearing anywhere in it or mentioning it in his correspondence, and is still sold and displayed in museums as one of his works. However, there is good evidence that this was a work produced by the well known Antwerp publisher Christophori Plantini for Severinus Gobelius, physician to the Duke of Prussia. Plantini had a large collection of wood-cuts, both produced in his workshop or purchased by him, with which he illustrated many of the major botanical publications of the time, which he assembled according to the classification used by Lobelius in his Kruydtboeck of the same year. This work was reissued in 1591 as Icones stirpium.
