(Κρίξος), a Gaul, was one of the two principal generals in the army of Spartacus, B. C. 73. Two Roman armies had already been defeated by the revolted gladiators and slaves, when Crixus was defeated in a battle near mount Garganus by the consul L. Gellius, in B. C. 72. Crixus himself was slain, and two-thirds of his army, which consisted of 30,000 men, were destroyed on the field of battle. Spartacus soon after sacrificed 300 Roman captives to the manes of Crixus.
