This paper aims to give some observations on the greek and latin Library of Pope Nicholas V. A case study is represented by Gregorius Tiphernas' translation of Timaeus Locrus, De natura mundi et animae, a useful reading for studying Plato' Timaeus, which has been preserved in the latin Library of Tommaso Parentucelli in Calcidius' translation (Vat. lat. 2063, from Coluccio Salutati): the greek exemplar used by Tiphernas, Biblioteca Angelica gr. 63, is a humanistic copy of a Bessarion's manuscript (Marc. gr. 186, a copy of Marc. gr. 517 of Pletho) of the corpus platonicum but the greek work has been preserved by Proclus; Tiphernas has then been involved by Nicholas V in his " Aristotle Project " , in continuity with Leonardo Bruni translations (Vat. lat. 2096). Of particular interest in the greek Library collected by the Pope is a Palaeologan manuscript of the XIV century, Vat. gr. 1087, partly written by Nicephorus Gregoras, and containing a large corpus of illustrations to Aratus' Phaenomena, with the Eratosthenic Fragments (Fragmenta Vaticana), membra disiecta of an " Edition Phi " of Aratus: the second part of this article provides a new analysis of some materials related to it (Letter to Julian; On the circle of the zodiac) in the light of a fresh examination of codex Vat. gr. 1291 (f. 9r, map of the zodiac) and Manilius, of Marc. gr. 476 and Par. gr. 2381 (Aratea).
