Though the Round Table is not mentioned in the earliest accounts, tales of
King Arthur having a marvellous court made up of many prominent warriors are ancient.
Geoffrey of Monmouth, in his
Historia Regum Britanniae (composed c. 1136) says that, after establishing peace throughout
Britain, Arthur "increased his personal entourage by inviting very distinguished men from far-distant kingdoms to join it." The code of
chivalry so important in later medieval romance figures in it as well, as Geoffrey says Arthur established "such a code of courtliness in his household that he inspired peoples living far away to imitate him." The fame of Arthur's entourage became so prominent in Welsh tradition that in the later additions to the
Welsh Triads, the formula tying named individuals to "Arthur's Court" in the triad titles began to supersede the older "Island of Britain" formula. Though the code of chivalry crucial to later continental romances dealing with the Round Table is mostly absent from the Welsh material, some passages of
Culhwch and Olwen seem to reference it. For instance, Arthur explains the ethos of his court, saying "[w]e are nobles as long as we are sought out: the greater the bounty we may give, the greater our nobility, fame and honour." Though no Round Table appears in the early Welsh texts, Arthur is associated with various items of household furniture. The earliest of these is Saint
Carannog's mystical floating
altar in that saint's 12th-century
Vita. In the story Arthur has found the altar and tries unsuccessfully to use it as a table; he returns it to Carannog in exchange for the saint ridding the land of a meddlesome dragon. Elements of Arthur's household figure into local topographical folklore throughout Britain as early as the early 12th century, with various landmarks being named "
Arthur's Seat", "Arthur's Oven", and "Arthur's Bed-chamber". A
henge at
Eamont Bridge near
Penrith,
Cumbria, is known as "
King Arthur's Round Table". The still-visible Roman amphitheatre at
Caerleon has been associated with the Round Table, and it has been suggested as a possible source for the legend. Following archaeological discoveries at the Roman ruins in
Chester, some writers suggested that the
Chester Roman Amphitheatre was the true prototype of the Round Table; however, the
English Heritage Commission, acting as consultants to a
History Channel documentary in which the claim was made, stated that there was no archaeological basis to the story. ==Legend==
