V. (28) With these words he deceived both those who were present and the youth himself; for his proposal was a mere bait, his intention being not to invest him with the power which he expected, but to deprive him of even that which he already had, according to the law affecting coheirs and partners; and accordingly now he plotted against him with absolute fearlessness, having no regard for nor fear of any one; for by the laws of the Romans the most complete and absolute authority over the son belongs to the father, besides the fact of Gaius having the imperial authority which was wholly irresponsible, since no one could either venture or had any power to demand an account from him of any thing whatever that he might do. (29) Accordingly, looking upon this youth to be like a thirds-man in the games, he proceeded to overthrow him, feeling no compassion, either for the fact of his having been brought up with him, or his being so nearly related to him, or for his age, but having no idea of sparing this miserable youth, doomed to an early death; his own partner in the government, his co-heir, who had formerly been expected to be all but the absolute emperor, by reason of his being the nearest relation to Tiberius; for when their fathers are dead, the grandsons are usually looked upon by their grandfathers as standing in the position of sons. (30) It is said moreover, that this youth, being ordered to slay himself with his own hands, while a centurion and a captain of a thousand were standing by (who had been expressly commanded to take no part in the horrid deed, since it was not lawful for the descendants of the emperors to be put to death by any one else; for Gaius remembered the laws amid his lawless acts, and had some regard for piety in all his impious deeds, imitating as well as he could the nature of truth); he, not knowing how to kill himself, for he had never seen any one else put to death, and had never had any practice in fighting with weapons, which is the usual exercise and course of instruction for children who are being educated with a view to become leaders and rulers, on account of the wars which they may have to conduct, at first exhorted those officers who had come to him to put him to death themselves, stretching out his neck; (31) but when they did not dare to do so, he himself taking the sword inquired in his ignorance and want of experience what was the most mortal place, in order that by a well-directed blow he might cut short his miserable life; and they, like instructors in misery, led him on his way, and pointed out to him the part into which he was to thrust his sword; and he, having thus learnt his first and last lesson, became himself, miserable that he was, his own murderer under compulsion.
