Penitent Magdalen (c. 1593-1594). Caravaggio (Michelangelo Merisi). Galleria Doria Pamphilj, Rome. Image courtesy of Olga's Gallery.
Notice the Grail on Magdalen's underdress. The Galleria Doria Pamphilj's website mentions that:
. . . the provenance of this picture is uncertain. It is mentioned, however, in an eighteenth-century inventory with a frame which displays the Aldobrandini arms, a detail which perhaps allows us to deduce that it originally belonged to the collection of Pietro.
