Mystery:  five single panels -

(Apparently: unattached (predella?)  panels, of uncertain origin): 

St. James Freeing Hermogenes;  

Zachary naming St. John the Baptist. 

Dormition

St. Lucy

St. Dominic Meeting St. Francis; 

 Note:  Three (?) of the five are in the U.S.; the fifth is . . .  

These five paintings were originally parts of the predella of one or more dismantled altarpieces.  In the last decade, it has been shown that they were all part of a single predella.   The Pontassieve Madonna has been proposed as its central panel.

According to the thirteenth-century Golden Legend,  the magician Hermogenes had sent devils to conquer the apostle Saint James the Greater.  The devils had instead bound Hermogenes himself.   In the painting, St. James taps Philetus, a Christian convert, on the shoulder, thereby empowering him to loosen Hermogenes and free him.
