It is said, that against this battle, Marius first altered the construction of the Roman javelins. For before, at the place where the wood was joined to the iron, it was made fast with two iron pins; but now Marius let one of them alone as it was, and pulling out the other, put a weak wooden peg in its place, thus contriving, that when it was driven into the enemy's shield, it should not stand right out, but the wooden peg breaking, the iron should bend, and so the javelin should hold fast by its crooked point, and drag.

Catulus commanded twenty thousand three hundred, and Marius thirty-two thousand, who were placed in the two wings, leaving Catulus the centre.

They tell us, also, that Catulus himself alleged this in vindication of his honor, accusing, in various ways, the enviousness of Marius.
