M. Atius Balbus, plebeian, of Aricia, married Julia, the sister of Julius Caesar, who bore him a daughter, Atia, the mother of Augustus Caesar. [atia.] He was praetor in b. c. 62, and obtained the government of Sardinia, as we learn from the annexed coin (copied from the Thesaur. Morett.), of which the reverse is atius balbus pr., with the head of Balbus; and the obverse, sard. pater, with the head of Sardus, the father or mythical ancestor of the island. In B. c. 59, Balbus was appointed one of the vigintiviri under the Julian law for the division of the land in Campania; and, as Pompey was a member of the same board, Balbus, who was not a person of any importance, was called by Cicero in joke Pompey's colleague.
