 The "Repentance of Peter", showing the end of the episode of the "Denial of Peter", was not often seen before the Counter-Reformation, when it became popular as an assertion of the sacrament of Confession against Protestant attacks.This followed an influential book by the Jesuit Cardinal Robert Bellarmine (1542–1621).The image typically shows Peter in tears, as a half-length portrait with no other figures, often with hands clasped as at right, and sometimes "the cock" in the background; it was often coupled with a repentant Mary Magdalen, another exemplar from Bellarmine's book.
