Bartolomeo Eustachi [Eustachius] c.1510/1520 produced and completed these fine plates himself in 1552 only for them to remain hidden in the Vatican library until the early 18th century when they were discovered and presented by Pope Clement XI to his physician Giovanni Maria Lancisius who published them in 1714.  His copper plates are considered more accurate than those of Vesalius and, had they appeared when executed in 1552, Eustachius would have ranked with Vesalius as one of the founders of modern anatomy.  Morton 391
