In a disguised way, Goya in the Caprichos drew a parallel between witchcraft and the activities of the clergy. He stressed the resemblance between witches and friars in their obedience to the hierarchy of their calling, the younger deferring to the older. In plate 47, Obsequio al maestro (“Homage to the master”), an apparently senior witch looks down with stony disdain at another, who ois offering her (or him) the gift of a dead baby; the supplicant’s gesture reminds one of a groveling postulant kissing the cardinal’s ring. “Es muy justo,” runs the Prado text: “This is quite fair, they would be ungrateful disciples who failed to visit their professor, to whom they owe everything they know about their diabolical faculties.”
Plate 46, Correccion (“Correction”), shows a group of brujos, male witches, as seminarians, consulting “the great witch who runs the Barahona seminary” — whatever that institution may have been. Of course, Goya could not be too explicit about this: on the other side of any public criticism of clerical practices lay the ever-watchful eye of the Inquisition, which Goya had to be at pains to avoid.
