Beoan of Mortlach

Holy Hierarch Beoan of Mortlach (Beóán, Bean) was the first of the three known bishops of Mortlach in Banff, Scotland, around 1012, and later preached at Aberdeen. He is a saint of the undivided Church.

The chroniclers Walter Bower and John of Fordun say that King Máel Coluim II of Scotland founded the bishopric in the seventh year of his reign (1012) in thanks for victories over the Scandinavians, and that the first bishop was Beyn, a saintly man, placed in the see by Pope Benedict VIII at the king's request. A charter in the Aberdeen register has the king granting Bishop Beóán the churches and lands of Clova. The Aberdeen Breviary commemorates him as a saint on 26 October. Another Beóán, perhaps the one in the Life of Saint Cathróe of Metz, was commemorated on 16 December, and the two were often confused.

He is commemorated on 26 October, the liturgical date in the Orthodox calendar (the same day number on the old and new calendars).
