The Tale of Peter and Fevronia
The fullest account of the saints comes not from a conventional life but from 'The Tale of Peter and Fevronia of Murom,' a sixteenth-century work traditionally ascribed to Hermolaus-Erasmus (Yermolai-Erasm), a churchman from Pskov who later became a monk. Though the written tale dates to the mid-sixteenth century, it draws on older oral legend, and it interweaves hagiography with folkloric and fairy-tale motifs to an unusual degree.
In the tale, Peter slays a serpent that had been afflicting the princely household, and the serpent's blood brings upon him the scabs and sickness from which Febronia, prized for her wisdom and cleverness, then heals him. A recurring motif relates that after the saints were buried apart, in keeping with monastic custom, their bodies were repeatedly found reunited in one grave, which the tradition reads as a sign that they were not to be separated even in death.
