Note 404 — APPENDIX C EXCURSUS
Reading edition
The name of this place, whether in the form Ebmoria (Lib. Arm.) or in the variant form Euboria (for the variants see Bury, “Tradition of Muirchu’s Text,” p. 185) is unknown. The context shows that it lay between Auxerre and the north coast of Gaul. Ebroica = Evreux would be my guess. (It probably became the seat of a bishop before the end of the fifth century, but probably not long before. Cp. Duchesne, Fastes ép. ii. 226).
