The renessiance of anatomy began as early as XVth century. In the XVIth century it developed tremendously; two theatres for dissection were established, one in 1552 in Venice and the other in 1556 in Montpeilier, although in the latter university dissections had been made for years, for we know that Rabelais dissected there in 1532. Anatomical discoveries became numerous through the work of Junther of Undernach (1487-1574), Fallopius (1523-1562), Michael Servetus (1509-1553), Andreas Vesalius (1514-1564), Gaspar Bauhin (1560-1624), Berenger of Carpi (1480-1550), Andreas Caesalpinus (1524-1603), J.C. Arantius (1530-1589), Voicher Coiter (1534-1600), John Philip Ingrassias (1510-1580), Fabricius ab Aquapendente (1537-1619), Barthoiomeus Eustachius (1520-1574), and Realdus Columbus (1516-1559); in 1559 he described the pulmonary circulation.
