 The In calumniatorem Platonis was originally printed in 1469 in Rome (by Schweynheym and Pannartz), and then again in 1503 and 1516 in Venice (by Manutius). Both Venetian editions—which slightly differ from one another—contain revisions suggested by Bessarion himself. Ludwig Mohler’s modern edition is based on the text printed by Manutius. See
