a Roman sculptor, whose name appears on two inscriptions, the one published by Boissard (Antiq. Roman. p. iii. fig. 132), the other in the Museum of the Louvre. From the latter it seems, though there is some doubt as to the true reading of the inscription, that the artist's full name was Titius Gemellus. (Sillig, Catal. Artif. s. v. ; R. Rochette. Lettre à M. Schorn, p. 419.)
