On that same day did Arthur found his Order of the Round Table, the fame of which was to spread throughout Christendom and endure through all time. Now the Round Table had been made for King Uther Pendragon by Merlin, who had meant thereby to set forth plainly to all men the roundness of the earth. After Uther died, King Leodegrance had possessed it; but when Arthur was wed, he sent it to him as a gift, and great was the King's joy at receiving it. One hundred and fifty knights might take their places about it, and for them Merlin made sieges or seats. One hundred and twenty-eight did Arthur knight at that great feast; thereafter, if any sieges were empty, at the high festival of Pentecost new knights were ordained to fill them, and by magic was the name of each knight found inscribed, in letters of gold, in his proper siege. One seat only long remained unoccupied, and that was the Siege Perilous. No knight might occupy it until the coming of Sir Galahad; for, without danger to his life, none might sit there who was not free from all stain of sin.
With pomp and ceremony did each knight take upon him the vows of true knighthood: to obey the King; to show mercy to all who asked it; to defend the weak; and for no worldly gain to fight in a wrongful cause: and all the knights rejoiced together, doing honour to Arthur and to his Queen. Then they rode forth to right the wrong and help the oppressed, and by their aid, the King held his realm in peace, doing justice to all.
Now when Arthur was first made King, as young knights will, he courted peril for its own sake, and often would he ride unattended by lonely forest ways, seeking the adventure that chance might send him. All unmindful was he of the ruin to his realm if mischief befell him; and even his trusty counsellors, though they grieved that he should thus imperil him, yet could not but love him the more for his hardihood.
So, on a day, he rode through the Forest Perilous where dwelt the Lady Annoure, a sorceress of great might, who used her magic powers but for the furtherance of her own desires. And as she looked from a turret window, she descried King Arthur come riding down a forest glade, and the sunbeams falling upon him made one glory of his armour and of his yellow hair. Then, as Annoure gazed upon the King, her heart grew hot within her, and she resolved that, come what might, she would have him for her own, to dwell with her always and fulfil all her behests. And so she bade lower the drawbridge and raise the portcullis, and sallying forth accompanied by her maidens, she gave King Arthur courteous salutation, and prayed him that he would rest within her castle that day, for that she had a petition to make to him; and Arthur, doubting nothing of her good faith, suffered himself to be led within.
