The freedom enjoyed by the Church under Caracalla is proved by the _graffiti_ of the Domus Gelotiana, described in my "Ancient Rome."[7] The one caricaturing the crucifixion, which is reproduced on p. 122 of that volume, stands by no means alone in certifying to the spreading of the faith in the imperial palace. The name of Alexamenos, "the faithful," is repeated thrice. There is also a name, LIBANUS, under which another hand has written EPISCOPUS, and, lower down, LIBANUS EPI[SCOPUS]. It is very likely a joke on Libanus, a Christian page like Alexamenos, whom his fellow-disciples had nicknamed "the bishop." It is true that the title is not necessarily Christian, having been used sometimes to denote a municipal officer;[8] but this can hardly be the case in an assembly of youths, like the one of the Domus Gelotiana; and the connection between the _graffiti_ of Libanus and those of Alexamenos seems evident. In reading these _graffiti_, now very much injured by dampness, exposure, and the unscrupulous hands of tourists, we are really witnessing household quarrels between pagan and Christian dwellers in the imperial palace, in one of which Caracalla, when still young, saw one of his playmates struck and punished on account of his Christian origin and persuasion. Septimius Severus and Caracalla issued a constitution,[9] which opened to the Jews the way to the highest honors, making the performance of such ceremonies as were in opposition to the principles of their faith optional with them. What was granted to the Jews by the law of the empire may have been permitted also to the Christians by the personal benevolence of the emperors. When Elagabalus collected, or tried to collect, in his own private chapel the gods and the holiest relics of the universe, he did not forget Christ and his doctrine.[10] Alexander Severus, the best of Roman rulers, gave full freedom to the Church; and once, the Christians having taken possession of a public place on which the _popinarii_, or tavern-keepers, claimed rights, Alexander gave judgment in favor of the former, saying it was preferable that the _place_ should serve for divine worship, rather than for the sale of drinks.[11] [Illustration: Portrait Bust of Philip the Younger.] There can scarcely be any doubt that the emperor Philip the Arab (Marcus Julius Philippus, A. D. 244), his wife Otacilia Severa, and his son Philip the younger were Christians, and friends of S. Hippolytus. Still, in spite of these periods of peace and freedom of the Church, we cannot be blind to the fact that for a Christian nobleman wishing to make a career, the position was extremely hazardous. Hence we frequently see baptism deferred until mature or old age, and strange situations and even acts of decided apostasy created by mixed marriages.
