The cell in the campanile in which the Blessed Peter Crisci lived and died was documented by Ludovico Jacobilli in the 17th century.  It was rediscovered in the 1970s and has since been restored.   (The sacristan is sometimes able to open the cell for visitors.)

Frescoes (ca. 1400)

Ludovico Jacobilli described the frescoes in the cell, which were still in good condition.   They were probably executed at the time that Pope Boniface IX granted indulgences to those praying before the relics of the Blessed Peter in the Duomo “in festo sancti Petri” (i.e. in either 1391 or 1400, according to different readings of the damaged document).

The surviving frescoes, which are attributed to the Maestro dell’ Abside Destra di San Francesco di Montefalco, depict:

   ✴the mystic marriage of St Catherine (illustrated above) on the back of the arch in which Peter Crisci slept: the kneeling donor to the left (illustrated again here) may well be Ugolino III Trinci;
