Teilo
Teliau
A legendary Welsh saint.
In the Life of St. Cadoc, he joins St. David and St. Cadoc in mediating a dispute between Arthur and Ligessauc, in which Arthur agreed to accept payment of 100 cows in return for the deaths of three of his knights at Ligessauc’s hands.
According to Geoffrey of Monmouth, Teilo was a priest from Llandaff who Arthur appointed as the Archbishop of Dol after Samson, the previous archbishop, left the post.
