Note 178 — NO. XXIII.—CARTHAGE.
Reading edition
Polybius acquaints us, that the ratification of the articles of agreement between the Romans and the Carthaginians, was performed in this manner: the Carthaginians swore by the gods of their country; and the Romans, after their ancient custom, swore by a stone, and then by Mars. They swore by a stone thus:—
"If I keep my faith, may the gods vouchsafe their assistance, and give me success; if, on the contrary, I violate it, then may the other party be entirely safe, and preserved in their country, in their laws, in their possessions, and, in a word, in all their rights and liberties; and may I perish and fall alone, as now this stone does:" and then he lets the stone fall out of his hands.
Livy's account of the like ceremony is something more particular; yet differs little in substance, only that he says the herald's concluding clause was, "otherwise may Jove strike the Roman people, as I do this hog;" and accordingly he killed a hog that stood ready by, with the stone which he held in his hand.—Kennett.
