Arthur had, of course, to be laid to rest, and so disabled as a symbol of Welsh resistance to Anglo-Norman domination, and this was achieved spectacularly at Glastonbury, where his remains(alongside those of Guinevere) were ‘discovered’ in 1191 ( ).
HAAAAALEEEEELUUUUJAHHHHH!!! MUCHAS GRACIASSSS!!!! Right! Here is the best section everrrr!!! Edward I utilised the squashing of the athur myth and the phrophecy of his return to disable 'a symbol of Welsh resistance to Anglo-Norman domination' P.14)
As the was later to note, no burial place was known for Arthur –Stanzas of the Gravesunsurprising, of course, if his origins lay in the fusion of folklore and political utility
This gives evidence for the significance ofit's finding then
Adam of Damerham King Arthur and Glastonbury (18th April)
Again, another good source for Arthur, this time gives context for the second source and the reburial of arthur
By the late thirteenth century, Glastonbury -- some twelve miles from Cadbury -- was already a place with strong Arthurian connections. Identified by Geoffrey of Monmouth as the site of the legendary Avalon, resting-place of Joseph of Arimathea who took possession of the Holy Grail after the Crucifixion, it had already attracted the attention of Henry II and Richard I.(2) However, it was Edward I whose interest in the Glastonbury legend was particularly strong. He owned a prose Tristan, conducted Arthurian-inspired tournaments, linked his Welsh and Scottish campaigns to the legend, and created festivals which he called `Round Tables' in emulation of his mythical role-model.(3) His most conspicuous act in this regard was to order that the alleged tomb of Arthur and Guinevere, `discovered' at Glastonbury in the twelfth century, be opened and that the remains be removed from their resting-place in the lady chapel and then re-interred in the main church
Good quote for background of Edward I's obsession with Arthur
