New iconic subjects popularized in the Baroque period included the Sacred Heart of Jesus, and the Immaculate Conception of Mary; the definitive iconography for the latter seems to have been established by the master and then father-in-law of Diego Velázquez, the painter and theorist Francisco Pacheco, to whom the Inquisition in Seville also contracted the approval of new images. The Assumption of Mary became a very common subject, and (despite a Caravaggio of the subject) the Death of the Virgin became almost extinct in Catholic art; Molanus and others had written against it.
