CHRYSIPPUS (c. B.c.), Greek philosopher, third leader of the Stoics, born at Soli, Cilicia (Diog. Laert. vii. 179). He came to Athens and studied possibly under Zeno, certainly under Cleanthes. It is said also that he became a pupil of Arcesi laus and Lacydes, heads of the middle academy. The comprehen siveness of his early studies left its mark on his philosophic work. His chief fame rested on his controversies in the academy, for which he was called "the column of the portico." Diogenes Laertius says "without Chrysippus there had been no Porch." Of the 75o treatises with which he is credited only fragments survive. The style is said to have been crabbed, the argument lucid.
