bishops' palace was later built there. The place became known first as ''Merthyr Tewdrig'' ("Tewdrig the martyr"), and later as ''Mateyrn'' ("place of a king") or Mathern.
[E. T. Davies, ''A History of the Parish of Mathern'', 1990] Tewdrig's defence of his homeland was said to be sufficiently decisive that the Saxons would not dare to invade again for thirty years.

[Hando, F.J., (1958) "Out and About in Monmouthshire", R. H. Johns, Newport.]
A number of sources, such as
Ussher's ''Brittanicarum Ecclesiarum Antiquitates'' (1639), cite Bishop
Godwin's 1615 account of the medieval church at Mathern. Godwin said that he discovered a stone coffin by the altar in the church, containing the saint's bones, and that the skull was badly fractured. Ussher also repeats the account of the ''Book of Llandaff''. In 1958
Hando also recounts the story told to him by an old lady who had lived in Mathern and who claimed to have seen for herself, in 1881, the stone coffin bearing the remains of St. Tewdrig with his mortal wound (a hole in the skull made by a spear-point) still visible.
