one of Caesar's legates in Gaul (Caes. Gal. 6.1, 7.83, 90). This Reginus appears to be the same person as the one whom Cicero mentions as his friend in B. C. 49 (ad Att. 10.12), and who had then the command of the coast of the Lower Sea. He is also in all probability the same as the C. Antistius Reginus, whose name appears as a triumvir of the mint on the coins of Augustus. On the coin annexed the obverse represents the head of Augustus, and the reverse various instruments used by the pontiffs. (Eckhel, vol. v. p. 137.)
