Athrwys ap Meurig

Athrwys ap Meurig (c. 605–655) was a prince, and possibly king, of Gwent and Glywysing in Wales. He was the son of King Meurig ap Tewdrig and the father of the later king Morgan ab Athrwys. It is possible he died before his father Meurig and did not live to rule as king himself.

Athrwys's name is spelled variously. It is spelled Atroys in the 10th century Welsh Harleian genealogies and Andrus in the early medieval Latin Life of Saint Cadoc; also note Andres[us] son of Morcant[us] in the same section of the saint's life, all derived from an early Old Welsh spelling *Antres.[1]

He was the son of Meurig ap Tewdrig, a King of Gwent and Glywysing in South Wales.[2] His mother was Onbrawst, daughter of Gwrgan Fawr, King of Ergyng. His siblings were Idnerth and Ffriog.[3] His wife may have been Cenedlon ferch Briafael Frydig; his children included Morgan ab Athrwys, later a king of Gwent, as well as Ithel and Gwaidnerth.[2] While Athrwys's father Meurig and son Morgan are named as kings in the Book of Llandaff, Athrwys is only named as a king of Gwent in a charter which is believed to be spurious (on chronological grounds, due to the witnesses of the charter). Wendy Davies concluded that Athrwys predeceased his father and thus never ruled as king, and when Meurig died after a long reign the kingship passed to Morgan. Davies suggests Athrwys lived between about 605–655.[4]

His son was Morgan ab Athrwys or Morgan Mwynfawr 'Morgan the Benefactor' in the Welsh language. Morgan was King of Morgannwg, or Gwent and Glywysing, land as far west as the River Towy and also encompassing land beyond the River Wye, into the old Kingdom of Ergyng, South Herefordshire.

Arthurian connectionEdit

Some writers have identified Athrwys ap Meurig as a potential historical basis for King Arthur. This identification is found at least as early as Thomas Carte's A General History of England, written in 1747. It was later put forward and popularised by William Owen Pughe in 1803. The theory subsequently gained more popularity during the 19th-century.

Proponents of the identification of Athrwys ap Meurig with Arthur generally point to the fact that Athrwys was a prince (and possibly king) of Glywysing, Gwent and Ergyng, which is where King Arthur is placed in many sources. For example, the Mabinogion (along with Geoffrey of Monmouth) describes Caerleon-upon-Usk as Arthur's main city, and the pre-Galfridian Life of St Cadoc also places Arthur in this region. Proponents of this theory argue that Athrwys lived in the sixth century, not the seventh century as is commonly believed by scholars. Thus, they argue that Athrwys lived at the same time as Arthur and in the same place as Arthur, indicating that they were, in reality, the same person. The name Athrwys, some argue, may be a corruption of one of the Latin forms of Arthur's name, such as Arthurus or Arturus.

Critics of this theory point out that the Annales Cambriae reports the death of Ffernfael son of Ithael in 775. This is widely accepted as being Ffernfael ap Ithael ap Morgan ap Athrwys. If the great-grandson of Athrwys died in 775, that makes it virtually impossible for Athrwys to have lived in the sixth century; he must instead be a seventh-century individual (if the identification of the Ffernfael of the Annales Cambriae with his great-grandson is correct). This means that he would not have lived at the same time as Arthur. In addition, most scholars believe that the name Athrwys comes from *Antres, not Arthur.
