This period saw me publication of his translations of two Platonic works, Alcinous on Plato's Doctrine and the Platonic Definitions of Speusippus
. Ten of the dialogues were also ready before Cosimo died as well as Ficino's major commentaries on Plato's Philebus (published 1464), on ethics and the highest Good, and on the Symposium (published 1469).
Rather than remain in the Academy after Plato's death when the headship passed to Plato's nephew, Speusippus
, Aristotle left Athens for Assos and there founded his own school.
46-7 asserts that Philolaus mentioned prime numbers The reference to Philolaus is in Speusippus
At XIV.4.13-14 Eusebius summarizes the first line of successors, Speusippus

Philosophies that would fit here are Stoicism, which identifies God both with the active, rational element of the universe, and with one of its material components, (44) and evolutionary models (such as Aristotle attributes to Speusippus
) in which the simple first is actualized by expressing itself in the production of diversity, just as a grown plant actualizes the potency of a seed.
