 In Titian's "Jacopo Pesaro being presented by Pope Alexander VI to Saint Peter" (probably before 1512, Royal Museum of Fine Arts, Antwerp) Saint Peter is enthroned above a painting of a classical relief which can be compared to the one here in size, complexity, and its uncertain subject-matter.The work was bought in 1608 by Cardinal Scipione Borghese, nephew of Pope Paul V and a major collector and patron of art.It is now kept with other works from the Borghese collection in the Galleria Borghese in Rome.
