Peredur (, Old Welsh Peretur) is the name of a number of men from the boundaries of history and legend in sub-Roman Britain. The Peredur who is most familiar to a modern audience is the character who made his entrance as a knight in the Arthurian world of Middle Welsh prose literature. Gwrgi and Peredur, sons of Eliffer Gwrgi and Peredur are listed as sons of Eliffer (Old Welsh: Elidir or Eleuther) "of the great warband" (cascord maur) and as sons of the Coeling dynasty in the Harleian genealogies, making them first cousins of Urien. Likewise, a pedigree from Jesus College MS 20 includes Gwrgi and Peredur as brothers together with one Arthur penuchel. Their principal claim to fame rests on their having fought in the Battle of Arfderydd. The Annales Cambriae report that this battle (bellum Armterid) was fought in 573, but gives no further detail. A later expansion of the entry names Gwrgi and Peredur, both described as sons of Eliffer, as the chieftains on the victorious side and tells that Gwenddoleu ap Ceidio was defeated and slain in the battle. Under the year 580, the Annales Cambriae record the deaths of Gwrgi (Guurci) and his brother Peredur (Peretur). These references give them a place as heroes in the Hen Ogledd of the late 6th century. Further detail is supplied in later legendary traditions, notably those represented by the Welsh Triads (Trioedd Ynys Prydein). One listing the three "Horse-Burdens" of Britain relates that Gwrgi, Peredur, Dynod Bwr and Cynfelyn Drwsgl were carried by a horse called Corvan, which enabled them to watch the clouds of dust ("battle-fog") coming from Gwenddoleu and his (mounted) forces in the battle of Arfderydd. The circumstances in which Gwrgi and Peredur died are alluded to in a Triad which explains that they had one of "Three Faithless Warbands of the Island of Britain". Their warband abandoned them at Caer Greu on the day before a battle with Eda Glinmaur ("Great-Knee") and so they were slain. The Welsh Triads also refer to family relations. One on the "Three Fair Womb-Burdens" of Britain, preserved incompletely in Peniarth MS 47, suggests that Peredur and Gwrgi had a sister called Arddun, while a variant version in Peniarth MS 50 calls the third sibling Ceindrech Pen Asgell ("Wing-head") and names the mother Efrddyl verch Gynfarch. Peredur is said to have had a son by the name of Gwgon
