Holy Prince Peter (David in monasticism) and Holy Princess Febronia (Euphrosyne in monasticism), Wonderworkers of Murom. Prince Peter was the second son of the Murom prince Yuri Vladimirovich. He entered upon the throne of Murom in the year 1203. Several years before this St Peter had fallen ill with leprosy, from which no one was able to heal him. In a vision it was revealed to the prince that the daughter of a bee-keeper would be able to heal him: the pious maiden Febronia, a peasant of Laskova village in Ryazan gubernia. St Peter sent his emissaries to this village.
