occurs in Juvenal (12.44) as the name of a silver-chaser, evidently of high reputation at that time (comp. Schol.). Sillig (Append. ad Catal. Artif.) and the commentators on Juvenal, take the name either as entirely fictitious, or as meaning only a Samian artist, from Parthenia, the old name of Samos: but the same name occurs, in a slightly different form, C. Octavius Parthenio, with the epithet, Argentarius, in an inscription (Gruter, p. dcxxxix. 5; R. Rochette, Lettre à M. Schorn, pp. 376, 377, 2nd ed. Paris, 1845).
