Elaeth the King

Holy Right-⁠Believing Elaeth the King was, in the 6th century, a British ruler from the north of Britain, driven from his lands. He withdrew to Wales, to the island of Anglesey, and became a monk at the monastery of Saint Seiriol at Penmon. He is a saint of the undivided Church.

He is said to have been the son of Meurig ab Idno and Onen Greg. The Welsh calendars give his day as 10 November. The Black Book of Carmarthen, of the 12th century, attributes to him two religious poems of seven stanzas each, written in a strain of deepest piety. He is the reputed founder of St Eleth's Church at Amlwch in the north of Anglesey; a holy well nearby, Ffynnon Elaeth, regarded as having healing qualities, bears his name.

He is commemorated on 10 November, the liturgical date in the Orthodox calendar (the same day number on the old and new calendars).
