MS M.50, Fol. 24v

Slaying of St. Peter Martyr (fol. 24v, left)

St. Peter of Verona's fame as a preacher and miracle worker was such that Pope Gregory IX appointed him inquisitor general for the Milanese territories. The saint, depicted here in the white habit and black cloak of the Dominican order, was assassinated on 6 April 1252 by killers hired by the heretical Cathari.

Peter was slain by a fatal blow to the head: His smashed skull is one of the prized relics housed by St. Eustorgio's in Milan.
