a learned freedman of Cicero, who ordered him to attend upon his son ill B. C. 52; but as he left young Marcus without the knowledge of his patron, Cicero determined to declare his manumission void. As, however, we find Chrysippus in the confidence of Cicero again in B. C. 48, he probably did not carry his threat into effect. (Cic. ad Q. Fr. 3.4, 5, ad Att. 7.2, 5,11.)
