Numantian in the same century describes in verse his voyage from Rome to Gaul: one book of the poem is extant; he falls in with Christianity on two of the islands which lie in his course. He thus describes them as found on one of these: "The island is in a squalid state, being full of light-haters. They call themselves monks, because they wish to live alone without witness. They dread the gifts, from fearing the reverses, of fortune." He meets on the other island a Christian, whom he had known, of good family and fortune, and happy in his marriage, who "impelled by the Furies had left men and gods, and, credulous exile, was living in base concealment. Is not this herd," he continues, "worse than Circean poison? then bodies were changed, now minds." In the _Philopatris_, which is the work of an author of the fourth century, Critias is introduced pale and wild. His friend asks him if he has seen Cerberus or Hecate; and he answers that he has heard a rigmarole from certain "thrice-cursed sophists"; which he thinks would drive him mad if he heard it again, and was nearly sending him headlong over some cliff as it was. He retires for relief with his inquirer to a pleasant place, shadowed by planes, where swallows and nightingales are singing, and a quiet brook is purling. Triephon, his friend, expresses a fear lest he has heard some incantation, and is led by the course of the dialogue, before his friend tells his tale, to give some account of Christianity, being himself a Christian. After speaking of the creation, as described by Moses, he falls at once upon that doctrine of a particular providence which is so distasteful to Plutarch, Velleius in Cicero, and Cæcilius, and generally to unbelievers. "He is in heaven," he says, "looking at just and unjust, and causing actions to be entered in books; and he will recompense all on a day which he has appointed." Critias objects that he cannot make this consistent with the received doctrine about the Fates, "even though he has perhaps been carried aloft with his master, and initiated in unspeakable mysteries." He also asks if the deeds of the Scythians are written in heaven for if so there must be many scribes there.
