or ANEROESTES (Ἀνηρόεστος, Ἀνηροέστης), king of the Gaesati, a Gallic people between the Alps and the Rhone, who was induced by the Boii and the Insubres to make war upon the Romans. He accordingly invaded Italy in B. C. 225, defeated the Romans near Faesulae, but in his return home was intercepted by the consul C. Atilius, who had come from Corsica. A battle ensued near Pisae, in which the Gauls were defeated with immense slaughter, but Atilius was killed. Ancroestus, in despair, put an end to his own life. (Plb. 2.22, 26, &c., 31; comp. Eutrop. 3.5; Oros. 4.3; Zonaras, 8.20.)
