The island called Gwales is supposed to be that now named Gresholm, eight or ten miles off the coast of Pembrokeshire; and to this day the Welsh sailors on that coast talk of the Green Meadows of Enchantment lying out at sea west of them, and of men who had either landed on them or seen them suddenly vanishing. Some of the people of Milford used to declare that they could sometimes see the Green Islands of the fairies quite distinctly; and they believed that the fairies went to and fro between their islands and the shore through a subterranean gallery under the sea. They used, indeed, to make purchases in the markets of Milford or Langhorne, and this they did sometimes without being seen and always without speaking, for they seemed to know the prices of the things they wished to buy and always laid down the exact sum of money needed. And indeed, how could the seven companions of the Enchanted Head have spent eighty years of incessant feasting on an island of the sea, without sometimes purchasing supplies from the mainland? VI THE CASTLE OF THE ACTIVE DOOR Perfect is my chair in Caer Sidi; Plague and age hurt not who's in it-- They know, Manawydan and Pryderi. Three organs round a fire sing before it, And about its points are ocean's streams And the abundant well above it-- Sweeter than white wine the drink in it. Peredur, the knight, rode through the wild woods of the Enchanted Island until he arrived on clear ground outside the forest. Then he beheld a castle on level ground in the middle of a meadow; and round the castle flowed a stream, and inside the castle there were large and spacious halls with great windows. Drawing nearer the castle, he saw it to be turning more rapidly than any wind blows. On the ramparts he saw archers shooting so vigorously that no armor would protect against them; there were also men blowing horns so loud that the earth appeared to tremble; and at the gates were lions, in iron chains, roaring so violently that one might fancy that the castle and the woods were ready to be uprooted. Neither the lions nor the warriors resisted Peredur, but he found a woman sitting by the gate, who offered to carry him on her back to the hall. This was the queen Rhiannon, who, having been accused of having caused the death of her child, was sentenced to remain seven years sitting by the gate, to tell her story to every one, and to offer to carry all strangers on her back into the castle.
