His story is told in the Book of Llandaf (BLD 141-2). Teudiric gave up his
kingdom to his son Meurig in order to live the life of a hermit among the rocks
of Tintern. While he was thus employed the Saxons began to invade his kingdom.
When he had been king he had always overcome his enemies, but his son was in
danger of being dispossessed by the foreigners. An angel advised Tewdrig to go
and face the enemy and prophesied that they would be turned to flight as far as
Pwll Brochwel. Afterwards for the space of thirty years they would not dare to
invade the coutnry. But he himself would be wounded by a single stroke, and
would die peacefully in three days.
So he went with his sons's army and stood on the bank of the Wye at Rhyd
Tyndyrn. When the enemry saw him they turned in flight, but one of them threw a
lance and wounded him. He expressed a desire to be buried in the isle of Echni
[Flatholm]. Stags brought him in a carriage to a meadow near the Severn and
there he died.
The place where Tewdrig was buried was called Merthyr Tewdrig, now Matharn in
Gwent (BLD, WATU, WCO 90) and he is patron of the church (PW 79). His
commemoration is given in only one Welsh Calendar, on Jan 3 (LBS I.70).
Following the Life of Teilo in the Book of Llandaf we are told that Teilo
received gifts from Teudiric filio Teithpall one of the kings of his time (BLD
118). There are no charters to support this, and indeed Teilo was probably long
dead in his time. Teudubric heads the pedigree of the kings of Glywysing and
Gwent in HG 28 but his son Meurig is accidentally omitted. The JC 9 version
restores his son Meurig but makes Tewdrig son of Llywarch ap Nynnio ap Erb. ABT
15 agrees with the Book of Llandaf in making him the son of Teithfall ap Nynnio
ab Yrb. One suspects that the introduction of Teithfall as his father is due to
confusion with TEWDRIG AP TEITHFALL OF GARTHMADRUN (RIN 6669) who occurs in the
Brychan documents as grandfather of Brychan. This Tewdrig can hardly be the
same person, although in the Life of St. Cadog it seems that the two have been
confused because, as the ancestor Cadog, he is called "Teudiric who was
martyred in Gwent" son of Teithfall ab Idnerth ab Yrb.
