De humani corporis fabrica
De humani corporis fabrica libri septem (Latin for On the fabric of the human body in seven books) is a collection of textbooks on human anatomy written by Andreas Vesalius (1514–1564) and published in 1543.
The collection of books is based on his Paduan lectures, during which he deviated from common practice by dissecting a corpse to illustrate what he was discussing. Dissections previously had been performed by a barber surgeon under the direction of a doctor of medicine, who was not expected to perform manual labour. Vesalius' "hands-on" magnum opus presents a careful examination of the organs and the complete structure of the human body. This would not have been possible without the many advances that had been made during the Renaissance, including both artistic developments in literal visual representation and the technical development of printing refined woodcut engravings. Because of these developments and his careful, immediate involvement, he was able to produce illustrations superior to any produced previously.

Books of the Collection (based on Richardson and Carman's On the Fabric of the Human Body)
William Frank Richardson and John Burd Carman's On the Fabric of the Human Body is an English translation of Vesalius' work. In each volume, Richardson and Carman explain the topics of Vesalius' dissections, and present a brief timeline of his life. Their translation also allows the reader to refer to the relevant text using Vesalius' symbols in the illustrations of his dissections .
Book 1: The Bones and Cartilages
The first book constitutes about a quarter of the entire collection. It presents Vesalius' observations on human bones and cartilage, which he collected from cemeteries. It covers the physical appearance of human bones and the the differentiation of human bones and cartilage by function. In each chapter Vesalius describes the bones in great detail, explaining their physical qualities in different ways. In the opening chapters, Vesalius "gives general aspects of bones and skeletal organisation, dealing with the differences in texture, strength, and resilience between bone and cartilage; explaining the complex differences between types of joints and reviewing some basic elements of descriptive techniques and terminology." A major theme of this book is whether Galen described the bones of the human skeleton accurately. When Vesalius lectured on the human skeleton, he also had to present the bones of animals to give credibility to Galen's observations.
Book 2: The Ligaments and Muscles
Here Vesalius describes the structure of the muscles, the agents used in creating movement by the body, and the material used to hold the joints together. Through his observations of butchers cutting meat, he was able to incorporate the skills they used in the dissection of the human body. The order in which to dissect a human body to effectively observe each muscle in the body is laid out. Each illustration displays a deepening view of the human body which can be followed while dissecting a human body. Vesalius also mentions the instruments needed to perform a dissection. Here Vesalius begins to describe how Galen's anatomical descriptions do not match his own observations. In order to not to show disrespect to Galen, he suggests Galen's use of anatomical structure is in fact correct, but not for humans. He even continues to describe some of the structures in the way Galen would.
Book 3: The Veins and Arteries, Book 4: The Nerves
In Books 3 and 4, Vesalius describes the veins, arteries, and nerves as vessels, but notes their differing physical structure: veins and arteries contains a hollow channel, but nerves do not. Vesalius describes the route by which air travels through the lungs and the heart. He describes this process as "a tree whose trunks divide into branches and twigs". He also describes how the body contains four veins (the portal vein, the venae cavae, the artery-like vein, and the umbilical vein) and two arteries (the aorta, and the vein-like artery) as being the main vessels which branch out into smaller veins and arteries. Vesalius lists some six hundred vessels in his tabulation of arteries, veins and nerves, but fails to mention the smaller vessels located in the hands and feet, the terminal vessels of the cutaneous nerves, or the vessels in the lungs and liver.
Book 5: The Organs of Nutrition and Generation
Vesalius gives detailed descriptions of the organs of nutrition, the urinary system, and the male and female reproductive systems. The alimentary and reproductive systems each make up about forty percent of this book, and the description of the renal system and the correct technique for dissecting it makes up the remainder. In the final chapter, the longest chapter of the entire collection, Vesalius gives detailed step-by-step instructions on how to dissect the abdominopelvic organs. In the first half of the book, Vesalius describes the peritoneum, the esophagus, the stomach, the omentum, the intestines and the mesentery. He then goes on to describe the liver, gall bladder, and the spleen. Finally, he describes the kidneys, the bladder, and the ureters. Although Vesalius was unfamiliar with the anatomy of pregnancy, he provides ilustrations of the placenta and the fetal membrane, making anatomical reference to Galen by comparing a dog's reproductive organs to those of a human.
Book 6: The Heart and Associated Organs, Book 7: The Brain
These books describe the structure and functions of the heart and the organs of respiration, the brain and its coverings, the eye, the organs of sensation, and the nerves of the limbs. A chapter is also devoted to the vivisection of the eye. Vesalius describes the organs of the body in great detail by commenting "on the variable strength of the attachment of the pleura to the thoracic walls, the strong attachment of the pericardium to the diaphragm, the shape and orientation of the ventricles of the heart, and the description of the semilunar valves." He closes each book with a chapter on the correct way to dissect the heart and the brain respectively.
Fabrica rectified some of Galen's worst errors, including the notion that the great blood vessels originated from the liver. While examining a human corpse, Vesalius discovered that Galen's observations were inconsistent with those of his, due to Galen's use of animal (dogs and monkeys) cadavers. Even with his improvements, however, Vesalius clung to some of Galen's errors, such as the idea that there was a different type of blood flowing through veins than arteries. It was not until William Harvey's work on the circulation of the blood that this misconception of Galen would be rectified in Europe.
Vesalius had the work published at the age of 28, taking great pains to ensure its quality, and dedicated it to Charles V, Holy Roman Emperor. The more than 250 illustrations are of great artistic merit and are generally attributed by modern scholars to the "studio of Titian" rather than Johannes Stephanus of Calcar, who provided drawings for Vesalius' earlier tracts, but in a much inferior style. The woodcuts were greatly superior to the illustrations in anatomical atlases of the day, which were never made by anatomy professors themselves. The woodcut blocks were transported to Basel, Switzerland, as Vesalius wished that the work be published by one of the foremost printers of the time, Johannes Oporinus. Vesalius' written directions to Oporinus (the iter) were so valuable the printer decided to include them. The illustrations were engraved on wooden blocks, which allowed for very fine detail.
The success of Fabrica recouped the work's considerable expense, and brought him European fame, partly through cheap unauthorized copies that rapidly appeared. He was appointed physician to the Holy Roman Emperor Charles V; Vesalius presented him with the first published copy (bound in silk of imperial purple, with specially hand-painted illustrations not found in any other copy). To accompany the Fabrica, Vesalius published a condensed, less expensive Epitome, which became more widely seen than the Fabrica'; it contained eight anatomical engravings that condensed visual material from the Fabrica, one illustration of the human skeleton taken directly from the Fabrica, and two new woodcut plates. Vesalius published a second edition of Fabrica in 1555; annotations in a copy of that edition donated to the Thomas Fisher Rare Book Library, University of Toronto, have been identified as Vesalius' own, showing that he was contemplating a third edition, never achieved.
A copy of the book bound in tanned human skin was donated to Brown University's John Hay Library by an alumnus. Its cover is "polished to a smooth golden brown" and, according to those who have seen the book, it looks like fine leather. Covering medical books in human skin was not an uncommon practice until the 18th century, utilizing the skin of executed convicts and poor people who died with no one to claim the body.
