12. Surnamed EPHILLUS, a Stoic philosopher, who is frequently mentioned by Diogenes Laertius, who attributes to him two works, one called φνσικὴ, and the other ἠθική. (D. L. 7.39, 41, 54, 64, 84, 102, 121, 125, 129, 135, 140.) Theon of Alexandria wrote a commentary on the φνσικὴ (Suid. s. v. Θέων, and Stobaeus (Eclog. Phys. i. p. 257, ed. Heeren) has preserved two fragments of it. This Stoic must be distinguished from the Academic philosopher Apollodorus who is spoken of by Cicero (De Nat. Deor. 1.34), but he is perhaps the same as the one who is mentioned by Tertullian (De Anima 15) along with Chrysippus.
