About Cristiolus of Wales
Cristiolus is a Welsh saint remembered at Llangristiolus on Anglesey. Peter Bartrum’s dictionary identifies him as its patron and records his feast on November 3. His name also appears in the traditions of Penrhydd and Eglwyswrw in southwest Wales.
His personal story is almost entirely unknown. He is traditionally placed in the sixth century, but that dating is not established by a contemporary life. Reliable dates of birth and death are lacking. The title “confessor” in accounts of his veneration does not establish whether he was a priest, monk or bishop.
A medieval genealogy links Cristiolus with Rhystud, presenting them as brothers descended from Emyr Llydaw, the legendary ruler associated with Brittany. The text belongs to a much later period than the saint’s supposed lifetime. Such lists were copied and expanded in Wales, with changes reflecting the knowledge and interests of their compilers. They tell us how communities connected their saints, but they cannot be treated as a contemporary family record.
At Eglwyswrw, the dedication has a complicated history. Archaeologist Neil Ludlow notes that the earliest known explicit association with Cristiolus appears in an account from 1811. Other writers identified the church with a saint called Erw, and earlier evidence also uses that name. The association with Cristiolus became established during the nineteenth century. This supports a history of devotion at the church, without proving that Cristiolus personally founded it.
The Church in Wales continues to list St Cristiolus at Llangristiolus in Bro Cadwaladr. His name remains attached to a place of worship even where the details of the life behind that name have been lost.
