Saint VELE ou VENET (BASILE), Celte de nation, ermite sur l'île de Ré (Vème siècle).

St. Siadhal  (Sedulius, Seadhal, Siadal)-

5th century. Sedulius (known in Irish as Siadhal, pronounced Shiel), was an Irish priest known as the Christian Virgil on the strength of his epic poem in five books Carmen Paschale. He left Ireland to found a school of poetry in Athens, proving that outstanding scholarship existed on the Emerald Isle prior to Saint Patrick. While he was still in Ireland, he may have been a disciple of Saint Ailbhe
