But the more cautious student will confine his attention to a group of but half-a-dozen places in South Wales, Devonshire, and Cornwall, and will doubt the truth of tradition even when it mingles with the nomenclature of the romance. Of Lyonnesse whelmed beneath the waves we have no knowledge; it is a lost and perhaps half fabulous region. Cameliard, whose boundaries are fairly well known, is strewed with doubtful relics, and preserves a multitude of strange stories. These are all that remain to us when we have traversed King Arthur’s land. Lyonnesse is reported to have been a region of extreme fertility, uniting the Scilly Isles with Western Cornwall. The hardy Silures were the inhabitants of this tract, and were remarkable for their industry and piety. No fewer than one hundred and forty churches testified to the latter quality, and the rocks called Seven Stones mark the site of their largest city. Tradition is untrustworthy as to any great cataclysm, but the Saxon chronicle declared that Lyonnesse was destroyed by a “high tide” on November 11, 1099. The assumption is that where the sea now sweeps with tremendous force, between Land’s End and the Scillies, once lay a fair region, another Atlantis, which formed no unimportant part of King Arthur’s realm. The etymology of the name Scilly is more or less doubtful. The word has been identified with Silura, or Siluria, the land of the Silures--that is, South Wales. Malory’s Surluse, or Surluce, reminiscent of the French Sorlingues, if it be not Scilly must remain unidentified. The first mention of it is in the history of La Cote Male Taile, where it is said that Sir Lancelot and the damsel Maledisant (afterwards known as Bienpensant) “rode forth a great while until they came to the border of the county of Surluse, and there they found a fair village with a strong bridge like a fortress.” A later reference shows that it was in and about Cornwall that the knights were at this time staying and seeking adventures with the king; and the “riding forth a great while to the border of the country of Surluse” would fit in with the idea that Cornwall and Scilly were not then divided by the sea, but formed part of the kingdom of Lyonnesse. Sir Tristram, who is essentially a Lyonnesse knight, was sought in the country of Surluse when he had vanished during the period of King Mark’s treachery; and there seems no doubt that, though an accessible part of the kingdom, it was a considerable distance away, and perhaps somewhat out of the beaten track. Sir Galahalt, “the haut prince,” was its ruler, and he was resorted to by the knights; but we are distinctly told that “the which country was within the lands of King Arthur,” and for that reason Sir Galahalt could not even arrange a joust without obtaining his sovereign’s consent. Again, Sir Galahalt was known as Sir Galahalt “of the Long Isles,” which admits of a fair deduction, and seems not without its significance in this argument.
