Dictionary of Greek and Roman Biography and Mythology/Hermagoras 2.

2. Surnamed Carion, likewise a Greek rhetorician, who lived in the time of Augustus, and taught rhetoric at Rome, together with Caecilius, and is called Hermagoras the younger. He was a disciple of Theodorus of Gadara. (Quint. Inst. iii. 1. § 18; Suid. s. v. Ἐρμαγόρας, who confounds the Temnian with Hermagoras Carion.) Whether the Hermagoras with whom Pompey, on his return from Asia, disputed at Rhodes Περί τῆς καθ̓ ὅλον ζητήσεως (Plat. Pomp. 42), is the younger or elder one, is uncertain.
