The pair of low reliefs with profiles of Popes, elegantly framed in grey marble are a high quality example of the trend of collecting images of the great and the good of the past, both in ecclesiastical and secular field, which enjoyed widespread appeal in Italian art scene of the first half of the 18th century. They are inspired by coins.
