4. L. Calpurnius
Piso Caesoninus., C. F. C. N. His last name shows that he originally belonged to the Caesonia gens, and was adopted by one of the Pisones, probably by No. 3, as he is indicated in the Fasti as C. F. C. N. This Piso brought dishonour on his family by his want of ability and of energy in war.
He was praetor in B. C. 154, and obtained the province of Further Spain, but was defeated by the Lusitani.
He was consul in B. C. 148 with Sp. Postumius Albinus, and was sent to conduct the war against Carthage, which he carried on with such little activity that the people became greatly discontented with his conduct, and he was superseded in the following year by Scipio. (Appian, App. Hisp. 56
