Tathan
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[1] and has dedications at Llanvaches, near Caerwent, also known as Llandathan,[2] and at St Athan. He is said to have been a teacher of Cadoc and to have brought light to the heathens to undo the work of Satan.
