Сан-Паоло-фуори-ле-Мура
A tradition from the eleventh century holds that Himerius and Gemolus were Nordic companions of a bishop who was traveling "Ad Limina Apostolorum"–that is, on a pilgrimage to the sepulchers of St. Peter and St. Paul at Rome, i.e., to the Basilica of St. Peter and to the Basilica of Saint Paul Outside the Walls.
