 His associations with Llandaff are very strong and it seems he was an early patron of the church there, where he is said to have placed relics of Saint Teilo, one of his predecessors as bishop.In the "Life of St. Oudoceus", Einion, King of Glywysing, is said to have been hunting a stag amongst the rocks and woods of the river Wye; when the stag reaching the cloak of Oudoceus lay down on it, the hounds were unable to touch it.Einion then made a gift of land to the saint.
