6. C.Cosconius, tribune of the plebs in B. C. 59, when he was one of the colleagues of P. Vatinius, aedile in 57, and one of the judices in the following year, 56, in the trial of P. Sextius. In the same year, C. Cato, the tribune of the plebs, purchased of Cosconius some bestiarii which the latter had undoubtedly exhibited the year before in the games of his aedileship. It seems that Cosconius subsequently obtained the aedileship, for Plutarch states, that Cosconius and Galba, two men of praetorian rank, were murdered by Caesar's soldiers in the mutiny in Campania, B. C. 47, and we know of no other Cosconius who is likely to have been praetor. (Cic. in uatin. 7, ad Q. Fr. 2.6; Plut. Caes. 51; comp. Dion. Cass. 42.52, Βουλευτὰς δύο.)
