Irenæus is alleged to have suffered martyrdon about 202, but there is no evidence of this prior to the ninth century, when Gregory of Tours first circulated a story to that effect. Even such orthodox writers as Cave, Basnage, Dodwell, and others, doubt the martyrdon, since neither Tertullian, Eusebius, Theodoret, nor other early writers refer to it. Two churches in Lyons dispupted for centuries about the possession of his relics, which the Catholics allege were afterwards sacriligeously despoiled by the Calvinists: a story often refuted. His sacred head is said to have been kicked about in the gutters, but of course it was miraculously restored to its place, and the skull, we believe, may be seen for a consideration at the present day. The original Greek text of the book against heresies is lost, and it exists only in a barbarous Latin version. At whatever time it was written, and it may probably be dated between 182 and 188, it testifies to the existence of numerous heresies in the Church. It contains many statements respecting the Gnostics, particularly the Valentinian heresy. There we may read of their peculiar theories concerning God and Christ. Some thought the Hebrew Jahveh a malignant deity whom Christ had come to destroy. Others were foolish and wicked enough to ask whence God got the matter for his creation. Cerinthus and his followers denied the virgin birth. Carpocrates and his school held that Jesus was the son of Joseph, and just like other men with the exception that inasmuch as his soul was stedfast and pure a power descended on him from the Father that by means of it he might escape from the creators of the world. Basilides taught that Jesus did not suffer death, but Simon of Cyrene, being compelled, bore the cross and was crucified in his stead. Irenæus does not forget to denounce these heretics as blasphemers and shameless sophists who speak not a word of sense. He calls them slippery serpents and other choice epithets such as the orthodox usually have in store for heretics, so that the reader is tempted to wish that the wretches could show cause why they should not summarily be damned. It is a notable fact that none of the heretical books or heretical gospels have been preserved; they come to us only through the medium of such representations as their opponents chose to make of them.
