[From this point there are considerable variations in the two narratives. The old man becomes, in the Recognitions, a prominent participant in the discussions, arguing with Peter, and with Niceta, Aquila, and Clement. At the close of these discussions he is recognised first by the sons (ix. 35), and then by his wife, as Faustinianus (ix. 37). In the Homilies Peter tells of an interview with the old man (xiv. 2–8), and the recognition takes place immediately upon his appearance (xiv. 9). Some discussion with him follows (Homily XV.); but soon the main controversy is with Simon Magus (Homilies XVI.–XIX.), in the presence of the father, who is convinced by Peter. Book x. contains much matter introduced in Homilies IV.–VII. The correspondences will be indicated in the footnotes.—R.]
