Epictetus and Simplicius

Epictetus' stoic philosophy is indeed perennial. Living 55-135 A.D., his was the culmination of stoicism. Simplicius, 'last of the neoplatonists', known primarily for his commentaries on Aristotle, wrote an important (i.e., to philosophers) commentary on the _Enchiridion of Epictetus_ which was actually written by Epictetus' student, Arrian, based on Epictetus' class lecture notes.
