Eustachio

Eustachio, BARTOLOMMEO, an Italian anatomist, who was physician-in-ordinary to the popes, and professor of Medicine in Rome, where he died in 1574. His name is indissolubly associated with anatomical science through his discoveries of the tube in the auditory apparatus (see EAR) and the rudimentary valve at the entrance of the inferior vena cava in the Heart (q.v.), which are called after him. These and other discoveries are recorded in his Opuscula Anatomica (Venice, 1564); his Tubulæ Anatomice were first edited by Lancisi in 1714.
