The Bolognese manuscript Archiginnasio B 3475 can be a significant witness of the practices used to teach Greek philosophy in late 15th-century Italy. It was compiled by the Italian humanist Pontico Virunio (alias for Ludovico da Ponte, c. 1465-1525) around 1490, as a fair copy of the notes he took during the university lectures of Niccolò Leoniceno (1428-1524), physician and philologist, professor at the University of Ferrara. The course whose topics are reflected in the recollectae was on three works of Aristotle: Meteorologica, De Caelo and Ethica ad Nichomacum – the first two being scientific/cosmological in character and the latter one on ethics. Written in a quite convulse humanistic script, the notes thus reelaborate the three Aristotelian works, on the one hand summarizing them and on the other hand widely expanding their content, with continuous references to various authors, both Greek and Latin, and to some Medieval commentators of Aristotle. This very noticeable stretching and reworking of the content of the three works constitute the main heteronomous aspect of the recollectae, which in turn also take the form of an autonomous commentary on Aristotelian cosmology and ethics.  A critical edition will be made of these notes, joined by a monographic part in which the recollectae of Virunio and the lectures of Leoniceno will be placed in the context of the Humanistic reception of Aristotle, especially in Ferrara.
