2. C.Curiatius, tribune of the people in B. C. 138, is characterised by Cicero (de Leg. 3.9) as a homo infimus. He caused the consuls of the year, P. Cornelius Scipio Nasica (whom he nicknamed Serapio) and D. Junius Brutus to be thrown into prison for the severity with which they proceeded in levying fresh troops, and for their disregard to the privilege of the tribunes to exempt certain persons from military service. (Liv. Epit. 55; V. Max. 3.7.3.)

There are extant several coins, on which we read C. CUR. TRIGE. or C. CUR. F., and which may belong to this tribune or a son of his; but it is just as probable that they belonged to some patrician C. Curiatius, about whom history furnishes no information. (Eckhel, v. p. 199, &c.) One C. Scaevius Curiatius, who lived in the early period of the empire, is mentioned in an inscription in Orelli (No. 4046) as duumvir in the municipium of Veii.
