3 And now that I have once mentioned the word “heresy,” where can I find a trumpet loud enough to proclaim the eloquence of our dear Lucinius, who, when the filthy heresy of Basilides raged in Spain and like a pestilence ravaged the provinces between the Pyrenees and the ocean, upheld in all its purity the faith of the church and altogether refused to embrace Armagil, Barbelon, Abraxas, Balsamum, and the absurd Leusibora. Such are the portentous names which, to excite the minds of unlearned men and weak women, they pretend to draw from Hebrew sources, terrifying the simple by barbarous combinations which they admire the more the less they understand them. The growth of this heresy is described for us by Irenæus, bishop of the church of Lyons, a man of the apostolic times, who was a disciple of Papias the hearer of the evangelist John.
He informs us that a certain Mark, of the stock of the gnostic Basilides, came in the first instance to Gaul, that he contaminated with his teaching those parts of the country which are watered by the Rhone and the Garonne, and that in particular he misled by his errors high-born women; to whom he promised certain secret mysteries and whose affection he enlisted by magic arts and hidden indulgence in unlawful intercourse. Irenæus goes on to say that subsequently Mark crossed the Pyrenees and occupied Spain, making it his object to seek out the houses of the wealthy, and in these especially the women, concerning whom we are told that they are “led away with various lusts, ever learning and never able to come to the knowledge of the truth.” All this he wrote about three hundred years ago in the extremely learned and eloquent books which he composed under the title Against all heresies.
