Eustachi of “Eustachian tube” fame was a sixteenth-century contemporary of Vesalius. He spent most of his professional career in Rome where he taught anatomy, performed autopsies at hospitals, and carried out dissections. Eustachi’s most famous contribution to anatomy was not available until 140 years after his death. By 1552 Eustachi had drawn and engraved 47 plates showing the human skeleton and muscles, but only eight plates were printed with text during his lifetime. Eventually all of the plates ended up in the Vatican Library. In the eighteenth century the papal physician, Giovanni Maria Lancisi, added explanations to the previously unpublished plates and published the complete set with text. While not as artistically stylish as Vesalius’s work, Eustachi’s volume is sometimes more accurate. If his entire collection of plates had been published ten years after Vesalius rather than 140 years later, it is probable that the two would have been honored as cofounders of modern anatomical study.
