According to Bulfinch's Mythology, Aneurin lived from between 500 a.d. and 550 a.d. This goes against some of my other research however, because the battle that he wrote about took place in 603a.d. Aneurin is attributed to having written the oldest piece of literature in Welsh by many. I have also found, however, that he was in fact a Scottish bard, and that the dialect of Gaelic that was in use at the time He wrote was most similar to later forms of Welsh. This Scotch theory makes more sense, because the battle of Cattraeth took place in Catterick, Yorkshire, close to Scotland and far from Wales. Even though the Gododdin is the oldest poem, it is the most authentic. Aneurin was one of the Northern Britons of Strath-Clyde, who have left to that part of the district they inhabited the name of Cumberland, or Land of Cymri. According to Oxford, sometime around 600 Mynyddawg Mwynfawr, a king of the North British people known as the Gododdin, assembled 300 Celtic warriors and feasted them for a year at his court in Edinburgh, before leading them south. At Catterick in Yorkshire they encountered the English hosts and in the ensuing battle all, or all but a handful, were killed. My unknown information states that the battle took place in 603 and waged for seven days before the Celts were wiped out by the invading Saxons, not English. You'll notice that even in the same translation, the number of warriors changes. I have the same quote from Sir Thomas Gray that is in Bulfinch's in one of the Oxford books, but there is a slight variation. Bulfinch says twice two hundred, and the Oxford says thrice two hundred. The names of the warriors that survived change widely as well. Aeron stays the same throughout, though the spelling changes occasionally. Conan, however, mutates heavily. The only trait that remains constant is the beginning consonant sound and usually the syllable count. The Conan who survived the battle in this poem was Lord of Miniadoc in Wales, who later collaborated with the Roman General Maximus in the conquest of Armorica, which they renamed Brittany or lesser Britain. The Owain who is the subject of several stanzas is not the Owain of Aurthurian legend. The Owain of the Holy Grail was the son of Urien, but the Owain of Aneurin is the son of Marro.
