3. SEX.PACUVIUS, tribune of the plebs, B. C. 27, in which year Octavian received the title of Augustus, outdid all his contemporaries in his flattery of Augustus, and devoted himself as a vassal to the emperor in the Spanish fashion. (D. C. 53.20.) Dio Cassius says, that according to some authorities his name was Apudius; but it would appear that Pacuvius is the right name, since Macrobius tells us (Sat. 1.12) that it was Sex. Pacuvius, tribune of the plebs, who proposed the pleliscitum by which the name of the month of Sextilis was changed into that of Augustus in honour of the emperor. This Sex. Pacuvius appears to be the same as the Pacuvius Taurus, upon whom Augustus perpetrated a joke, when he was one day begging a congiarium from the emperor. (Macr. 2.4.) The Sex. Pacuvius Taurus, plebeian aedile, mentioned by Pliny (Plin. Nat. 34.5. s. 11), was a different person from the preceding one, and lived at a more ancient time.
