Romulus, on the other hand, made use of their oblong shields, and changed his own armour and that of the Romans, who before that carried round shields of the Argive pattern.

One of these is the Matronalia, which was bestowed upon the women to commemorate their putting a stop to the war; and another is the Carmentalia.
