Pergamos

(Πέργαμος), an engraver on precious stones, whose name occurs on a stone in the collection of Prince Poniatowski, engraved with the portrait of Nicomedes IV. king of Bithynia ; whence it may be inferred that the artist lived about the time of Augustus. There is another gem ascribed to him by Bracci and Stosch, but in this case the true reading of the name is doubtful. (Visconti, Oper. Var. vol. ii. p. 360; R. Rochette, Lettre a\ M. Schorn, p. 147, 2nd ed.; comp. Pygmon.] [P.S]
