Calventius
an Insubrian Gaul, of the town of Placentia, and a merchant, whose daughter married L. Calpurnius Piso Caesoninus, the father of L. Calpurnius Piso Caesoninus, consul in B. C. 58. In his speech against the latter, Cicero upbraids him with the low origin of his mother, and calls him Caesoninus Semiplacentinus Calventius (in Pison, 6, 23; Ascon. in Pison, p. 5, ed. Orelli; comp. Cic. de prove. Cons. 4, pro Sext. 9); and in a letter to his brother Quintus (3.1.4), Piso is also meant by the name of Calventius Marius.
