2. C.Atius, the Pelignian, belonged to the Pompeian party, and had possession of Sulmo, when Caesar invaded Italy, B. C. 49. Caesar despatched M. Antony against the town, the inhabitants of which opened the gates as soon as they saw Antony's standards, while Atius cast himself down from the wall. At his own request he was sent to Caesar, who dismissed him unhurt. (Caes. Civ. 1.18.) Cicero writes (ad Att. 8.4) as if Atius himself had surrendered the town to Antony.
