Not till that moment did he realize the true character of what he was doing. The idea of the poem was very simple. He had taken the base history of his own life in this amazing summer, and was making of it a romantic and glorious poem. Everything was there⁠—Emily and his cruelty to Emily and the chivalry of John Egerton and his treachery to John, Margery, and Muriel, and his betrayal of both of them, and the second treachery to John in the stealing of Muriel. They were all there, and the deeds were there. But the names they bore were the names of old knights and fine ladies, moving generously through an age of chivalry and gallant ways; and the deeds he had done were invested with so rich a romance by the grace of and imagery and humanity of his verse, and by the gracious atmosphere of knighthood and adventure and forest battles which he wrapped about them, that they were beautiful. They were poetry. Himself in the story was a brave and legendary figure, Gelert by name, and Margery, the Princess, was his fair lady. And he had slain Emily by mischance in a forest encounter with another knight. He had hidden her body in a dark mysterious lake in the heart of the forest; this lake was beautifully described.
