The Horse Skeleton by Jean Héroard, 1599

The "doctor of veterinary sciences at the main stables of King Charles IX", Héroard was the first to accurately describe the contours of a horse's bones. His Hippostéologie would be the first volume in a series of books describing the entire anatomy of this noble animal. His appointment as doctor prevented the continuation of the project.
