Morgagni, in the preface to his own work, discusses the defects and merits of the "Sepulchretum": it was largely a compilation of other men's cases, well and ill authenticated; it was prolix, often inaccurate and misleading from ignorance of the normal anatomy, and it was wanting in what would now be called objective impartiality, a quality which was introduced as decisively into morbid anatomy by Morgagni as it had been introduced two centuries earlier into normal human anatomy by Vesalius.
