Senarius of Avranches

Saint Senarius of Avranches, hierarch (also Sinerius or Senator), was bishop of Avranches around the 6th century and is venerated as a saint in the Western Church. The Roman Martyrology remembers him on 18 September in the Western calendar.

Almost nothing is known of him. The oldest episcopal lists of Avranches put five saints at the beginning: Leontius, Paternus, Sinerius, Severus and Authbertus. Of these only Paternus and Authbertus can be placed in time. The traditions that make Senarius a bishop are late, from the 15th century, and the authors place his episcopate differently, from the middle of the 6th century to the second quarter of the 7th.
