Goeznovius of Léon

Holy Hierarch Goeznovius of Léon (Goueznou) was bishop of Léon in Brittany and is venerated in the region of Brest and in the diocese of Léon. The calendars give his repose as 675, but it seems more likely that he lived in the 6th century. He is a saint of the undivided Church.

His Life, the Legenda Sancti Goeznovii, written by a Breton chaplain named William, appears to date from the late 12th or the 13th century (the text itself gives the year 1019). It says he was born in Cornwall and was one of the many Britons who crossed to the continent after the Anglo-⁠Saxon invasions and helped found the Breton settlement in Armorica that became Brittany. The Legenda also has an unusual preface on the history of Brittany, in which Vortigern, the coming of the Saxons and King Arthur appear, a text of interest to students of the Arthurian legend.

He is commemorated on 25 October, the liturgical date in the Orthodox calendar (the same day number on the old and new calendars).
