'''Saint Tathan''' (also known as '''Tatheus''') is claimed to be a fifth or sixth century Celtic saint, who travelled from Ireland to Wales where he founded a Christian church. He is reckoned an early abbot of Caerwent<ref name = Hando>Hando, F.J., (1958) "Out and About in Monmouthshire", R. H. Johns, Newport</ref> and has dedications at Llanvaches, near Caerwent, also known as Llandathan,<ref>William Jenkins Rees, ''Lives of the Cambro British Saints'' (1853), [http://www.celticchristianity.infinitesoulutions.com/books/Vita_Saint_Tathan.pdf Chapter V 'Life of Saint Tathan', page 591].

==Origins== William Jenkins Rees, in his book ''Lives of the Cambro British Saints'', describes Tathan as the only son of the Irish King Tathetus. Tathan received a good education and devoted himself to spiritual matters. In preference to succeeding his father as king, Tathan followed the advice of an angel and sailed from Ireland to Britain, taking eight disciples with him. His boat sailed up the River Severn and landed in the medieval Kingdom of Gwent.<ref name="Cambro Saints">William Jenkins Rees, "Lives of the Cambro British Saints" (1853), [http://www.celticchristianity.infinitesoulutions.com/books/Vita_Saint_Tathan.pdf Chapter V 'Life of Saint Tathan'], reproduced on Celtic Christianity website. Retrieved 2012-05-07.</ref> Tathan was feted by King Caradoc and founded a monastic school at Venta Silurum (Caerwent). Scholars came from all parts to be instructed there. King Gwynllyw of Gwynllwg sent his seven-year-old son, Cadoc to study under Tathan.<ref name=pickering>[https://books.google.com/books?id=i5gbAQAAIAAJ&pg=PA240 Pickering, W., ''Archaeologia Cambrensis'', 1904]</ref> With a donation from Caradoc's son, Ynyr, Tathan then founded a Christian church.<ref name="Cambro Saints" />
