Beyond this a number of chambers have been discovered under the steep bank of the Palatine, and retain a quantity of _graffiti_ scratched upon their walls. The most interesting of these, found in the fourth chamber, has been removed to the museum of the Collegio Romano. It is generally believed to have been executed during the reign of Septimius Severus, and to have been done in an idle moment by one of the soldiers occupying these rooms, supposed to have been used as guard-chambers under that emperor. If so, it is perhaps the earliest existing pictorial allusion to the manner of our Saviour's death. It is a caricature evidently executed in ridicule of a Christian fellow-soldier. The figure on the cross has an ass's head, and by the worshipping figure is inscribed in Greek characters, _Alexamenos worships his God_. "The lowest orders of the populace were as intelligently hostile to it [the worship of the Crucified] as were the philosophers. Witness that remarkable caricature of the adoration of our crucified Lord, which was discovered some ten years ago beneath the ruins of the Palatine palace. It is a rough sketch, traced, in all probability, by the hand of some pagan slave in one of the earliest years of the third century of our era. A human figure with an ass's head is represented as fixed to a cross, while another figure in a tunic stands on one side. This figure is addressing himself to the crucified monster, and is making a gesture which was the customary pagan expression of adoration. Underneath there runs a rude inscription: _Alexamenos adores his God_. Here we are face to face with a touching episode of the life of the Roman Church in the days of Severus or of Caracalla. As under Nero, so, a century and a half later, there were worshippers of Christ in the household of Cæsar. But the paganism of the later date was more intelligently and bitterly hostile to the Church than the paganism which had shed the blood of the apostles. The Gnostic invective which attributed to the Jews the worship of an ass, was applied by pagans indiscriminately to Jews and Christians. Tacitus attributes the custom to a legend respecting services rendered by wild asses to the Israelites in the desert; 'and so, I suppose,' observes Tertullian, 'it was thence presumed that we, as bordering upon the Jewish religion, were taught to worship such a figure.' Such a story, once current, was easily adapted to the purposes of a pagan caricaturist. Whether from ignorance of the forms of Christian worship, or in order to make his parody of it more generally intelligible to its pagan admirers, the draughtsman has ascribed to Alexamenos the gestures of a heathen devotee. But the real object of his parody is too plain to be mistaken. Jesus Christ, we may be sure, had other confessors and worshippers in the Imperial palace
