Ab urbe condita

If the man who has been so devoted is killed, all is considered to have been duly performed. If he is not killed, an image of the man, seven feet high at least, must be buried in the earth, and a victim slain as an expiatory sacrifice; on the spot, where such an image has been buried, no Roman magistrate must ever set his foot.

If, as in the case of Decius, the commander devotes himself but survives the battle, he can no longer discharge any religious function, either on his own account or on behalf of the State. He has the right to devote his arms, either by offering a sacrifice or otherwise, to Vulcan or to any other deity.
