Emperor of [the] Romans. At first he handled the affairs of the empire in a high-minded fashion and dealt with his subordinates professionally. But after two years he deviated from human nature and, in imitation of his [sc. adoptive] father [sc. Tiberius], deified himself and sent a statue of himself to be set up in the temples of each of the cities. And he issued an edict to the temple of Jerusalem, demanding that it be called the shrine of the young Gaius [....] When decreeing slave-rule he permitted [slaves] to denounce their masters if they knew of any transgression on their parts. This caused a horrible catastrophe to rock the entire realm, as slaves subjected their masters to grievous penalties. For each of them wanted to avenge himself on his own master for the punishments he had suffered previously at his hands. And that is not all: descending into madness he improperly clothed himself in women's robes and bedecked his hair with curls and a kind of hairnet, and bearing himself like a woman he compassed all manner of shameful deeds; he devised rituals and performed foreign mystery ceremonies. Moreover, one time he took his own daughter and put her into the lap of the statue, saying, "you begot her and you are her rightful father."[1]
This man became the most defiled and the most unholy and conceived such an impulse toward evil that he made people forget the shortcomings of Tiberius. For all that had been gained by Augustus in a great length of time he lost in a single day. Having become the most debauched of men he even seized upon betrothed and married women, and charging his own nurse with stupidity he drove her to the point where she was compelled to die by her own hand. He also took advantage of his sisters and joined with them in illegal intercourse, so as to become even the father of unholy offspring born from one of these very sisters. He arranged that there be temples and sacrifices [to himself] as a demigod. The Romans were at the mercy of him as emperor, in such a way that the actions of Tiberius, though they were thought to have been most grievous, were surpassed by those of Gaius as much as those of Augustus were by that one [i.e. Tiberius].[2]
This man reigned after Tiberius and was called 'Caligula'.[3]
