Son of Albanian king Procas, younger brother of Numitor. He forced his brother to abdicate, had his brother's son killed, made his daughter Rhea Silvia a vestal and punished her for her pregnancy. Later Numitor was again restored to his rightful situation by Romulus and Remus, but A. was killed (Liv. 1,4,10-11; Dion. Hal. Ant. Rom. 1,79-83; Origo gen. Rom. 19-21)
