Two sculptures in the Musée du Louvre – portraying Saint Catherine of Alexandria presenting a kneeling clergyman to a Madonna and Child, following an iconographic motif widely used in Italian tomb sculpture – are linked together and attributed to the Sienese sculptor Agnolo di Ventura. Strong evidence suggests that these two pieces were part of the Tomb of Cardinal Matteo Orsini († 1340), whose surviving gisant is today embedded in the vestibule wall to the left of the apse in the Dominican church of Santa Maria sopra Minerva in Rome. Despite considerable losses, the discovery of the donor effigy corroborates the hypothesis that the original tomb was a canopied wall monument, a design typical of curial tombs.
