Erophilus

a distinguished engraver of gems, was the son of Dioscorides. He lived, therefore, under the early Roman emperors. He is only known by a beautiful gem, bearing the head of Augustus, on which his name appears, though partially defaced. (Meyer zu Winckelmann, B. 11.100.2.18, Abbildungen, No. 92; Müller, Arch. d. Kunst, § 200, n. 1.) [P.S]
