Origins and Dating
The sources preserve more than one account of Elian's background. In one, he is said to have come from Rome by sea, landing in Anglesey in northern Wales, where he founded a church around 450. In another, he is described as of Cornish or Breton stock and assigned to the sixth century. The repository's anchor record places him in the fifth century and identifies Cornwall as the field of his missionary work.
These divergent traditions reflect the scarcity of early documentation for the saints of this region, where commemoration is often anchored more firmly in dedications and place-names than in written lives.
