This precious object is made of silver and embossed foil, kept in a case made of bark, decorated with swirls and vegetal motifs. The author is unknown, but the object must have been certainly made in Rome. It is in fact certain that it was bought in 1762 by the prior Francesco Maria Bronzini, and donated to Gian Battista Magnaguti in 1810.The reliquary contains a fragment of the garment of the Blessed Osanna. It is a gift of Alessandro Magnaguti.
