a Roman painter, who was chiefly employed in decorating the Golden House of Nero. One of his works was a picture of Minerva, which always looked at the spectator, whatever point of view he chose. Pliny calls him "gravis et severus, idemque floridus," and adds, that he only painted for a few hours in the day, and that with such a regard for his own dignity, that he would not lay aside his toga, even when employed in the midst of scaffolding and machinery. (Plin. Nat. 35.37 : Voss, in an emendation of this passage, among other alterations, substitutes Fabullus for Amulius. His reading is adopted by Junius and Sillig; but there seems to be no sufficient ground to reject the old reading.)
