The other difficulty from which the record of Apollonius's life and teachings has suffered is due to the religious disputes which arose through the rapid growth of Christianity and its con?ict with the previously existing religions of the Roman world. We may argue legitimately enough that the power of working miracles is no proof of the truth of the doctrines expounded by any religious teacher. But the fact remains that in proselytising for Chris tianity the fullest use was made of the miracles recorded as accomplished by Jesus in the Gospels, in support of the contention in favour of the Divine origin of their worker, and of his work. Illogical though this argument may appear to the philosophic mind, it is not surprising that it should have carried great weight, and indeed it must be admitted that it does so even at the present day. What more natural, then, than that one of the disputants on the other side should have produced a polemical pamphlet in which he attempted to show that such.
