He was a son of the sister of Chrysippus, and became his pupil. Chrysippus dedicated several of his works to him. Of the few facts known about Aristocreon's life, it is known that between 229 and 190 BC, he was in Athens, where he obtained the official position of a Proxenos (a consular agent acting for another city). He was still alive in Athens in 184 BC. Plutarch records that Aristocreon erected a bronze statue of his uncle on a pillar and engraved a verse to him:
Of uncle Chrysippus Aristocreon this likeness erected;
The knots the Academy tied, the cleaver, Chrysippus, dissected.
