Note 93 — LIFE OF CAIUS MARIUS.
George Long translation
The Eagle, Aquila, was the Roman standard in use at this time. Formerly the Romans had five symbols for their standards, the eagle, wolf, minotaur, horse, and wild boar, all of which were appropriated to respective divisions of the army. Marius in this Cimbrian war did away with all of them except the eagle. (Plinius, N.H. x. 4.)
