Therefore, after the death[*](In 183 B.C.) of the Scipio who conquered Hannibal, although Tiberius had not been his friend, but actually at variance with him, he was judged worthy to take Scipio’s daughter Cornelia in marriage. We are told, moreover, that he once caught a pair of serpents on his bed, and that the soothsayers, after considering the prodigy, forbade him to kill both serpents or to let both go, but to decide the fate of one or the other of them, declaring also that the male serpent, if killed, would bring death to Tiberius, and the female, to Cornelia.
