Every physician has heard of him, yet few know the details of his life, the circumstances under which his labors were carried out, the extent of those labors, or their far-reaching influence upon the progress of anatomy, physiology and surgery. Comparatively few physicians have seen his works; and fewer still have read them. The reformation which he inaugurated in anatomy, and incidentally in other branches of medical science, has left only a dim impress upon the minds of the busy, science-loving physicians of the nineteenth and twentieth centuries. That so little should be known about him is not surprising, since his writings were in Latin and were published prior to the middle of the sixteenth century. His books, which at one time were in the hands of all the scientific physicians of Europe, are now rarely encountered beyond the walls of the great medical libraries of the world. They are among the _incunabula_ of the medical literature. That English-speaking physicians know little of Vesalian literature is due to the fact that no extensive biography of the great anatomist has appeared in our language. Most of the Vesalian literature which has been written by English and American authors has been in the form of brief articles for the medical press; these oftentimes have been incorrect and unillustrated. Perhaps the best example of this class is the article by Mr. Henry Morley which appeared originally in _Fraser’s Magazine_, in 1853, and later was published in his _Clement Marot and Other Studies_, in 1871.
