Because of the severe damage caused by
environmental agents during the short period in which it
adorned the façade of the Building, this triptych was

According to tradition, this work depicts Saints Leo,
Marino and Agata, but its correct interpretation is
called in question by the unusual clothing of Marino,
dressed as a Roman soldier. More plausible seems a recent
hypothesis, according to which the saint in the middle is
Saint Quirino, designated as protector of the
Republic in 1547.
This hypothesis also seems confirmed by the
fact that Saint Marino is nevertheless depicted on
the façade of the Building in the beautiful bronze statue
moulded by Giulio Tadolini.
