Chrysippus

Chrysippus of Soli was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of Cleanthes in the Stoic school. When Cleanthes died, around 230 BC, Chrysippus became the third head of the school. A prolific writer, Chrysippus expanded the fundamental doctrines of Zeno of Citium, the founder of the school, which earned him the title of Second Founder of Stoicism.

Chrysippus, the son of Apollonius of Tarsus, was born at Soli, Cilicia. He was slight in stature, and is reputed to have trained as a longdistance runner. While still young, he lost his substantial inherited property when it was confiscated to the kings treasury. Chrysippus moved to Athens, where he became the disciple of Cleanthes, who was then the head of the Stoic school. He is believed to have attended the courses of Arcesilaus and his successor Lacydes, in the Platonic Academy.
