a Roman painter, celebrated for small panel pictures. He was of praetorian rank, and was at one time proconsul of Gallia Narbonensis, in which office he made himself contemptible. He died at a great age, shortly before the time when Pliny the Elder wrote. (Plin. Nat. 35.4. s. 7.) The common reading is Ateius Labeo. Jan (Schulzeit. 1833, p. 723) suggested Titidius, which is adopted by Sillig, in his edition of Pliny. The MSS. are corrupt.
