And so the cry was made in England, Wales, and Scotland, Ireland, Cornwall, and in all the Out Isles, and in Brittany and in many countries; that at the feast of our Lady the Assumption next coming, men should come to the Castle Perilous beside the Isle of Avilion; and there all the knights that there came should have the choice whether them list to be on the one party with the knights of the castle, or on the other party with King Arthur. And two months was to the day that the tournament should be. And so there came many good knights that were at their large, and held them for the most part against King Arthur and his knights of the Round Table and came in the side of them of the castle.
