This memorial was realised by Angelo Piò (1690-1770) and anonymous fresco painter.
The sculpted marble portrait is austere and solemn, if we compare it to the usual style of the artist, a fine interpreter of the Bolognese Baroque style; on this occasion, he evidently wanted to adapt his style to the elegance of the location.
The profile portrait with a large wig recalls an analogous oval stucco medallion made by the artist in the Church of San Domenico to commemorate the general Luigi Ferdinando Marsigli, the founder of the Institute of Sciences.
