A relief over the door represents their parting, where this chapel now
stands. The inscription says:--
IN THIS PLACE SS. PETER AND PAUL SEPARATED ON THEIR WAY TO MARTYRDOM.
AND PAUL SAID TO PETER, "PEACE BE WITH THEE, FOUNDATION OF THE CHURCH,
SHEPHERD OF THE FLOCK OF CHRIST."
AND PETER SAID TO PAUL, "GO IN PEACE, PREACHER OF GOOD TIDINGS, AND
GUIDE OF THE SALVATION OF THE JUST."
