Cadoc (Cadocus, Docus, Cathmael, Cattwg The Wise)
abbot of Llancarvan, in Wales, was the son of Gundleus (or Gwynllyw Filwe), and was educated by an Irish anchoret, Menthi. He then went to Gwent (or Caerwent), Monmouthshire, where he. studied under St. Fathai. From Gwent he removed to Glamorgan, and founded the monastery of Llancarvan, of which he became first abbot. He was the friend of Dubricius, and the means of the conversion of St. Iltritus, He was born, probably, about the beginning of the 6th century; Colgan and Lanigan assign 570 as the date of his death. He was commemorated Jan. 14. The fables of Cattwg the Wise are printed in the lolo Manuscripts, edited by E. William (1848). His Life is given in the Acta Sanctorum of the Bollandists, under Jan. 2, 602. Colgan (Tr. Thaum. 152, 185, n.) seeks to identify the Mochatocars left by St. Fiac at Innisfail as the Cadocus of Wales, but the dates do not harmonize. He has also been confused with St. Sophias of Beneventum. His Scotch dedication was at Cambuslang, County 'Lanark.
