It was this dauntless and resolute character which prevented him from abandoning all idea of fighting when the omens were challenged. It was this, too, that made him in the very crisis of the struggle, at the moment when it is customary to vow temples to the gods, make a vow to Jupiter Victor that if he routed the legions of the enemy he would offer him a cup of sweetened wine before he drank anything stronger himself. This vow was acceptable to the gods and they changed the omens into favourable ones.
