For, as she now told Jurgen, she was Guenevere, the daughter of Gogyrvan, King of Glathion and the Red Islands. So Jurgen told her he was the Duke of Logreus, because he felt it was not appropriate for a pawnbroker to be rescuing princesses: and he swore, too, that he would restore her safely to her father, whatever Thragnar might attempt. And all the story of her nefarious capture and imprisonment by King Thragnar did Dame Guenevere relate to Jurgen, as they rode together through the pleasant May morning. She considered the Troll King could not well molest them. "For now you have his charmed sword, Caliburn, the only weapon with which Thragnar can be slain. Besides, the sign of the cross he cannot pass. He beholds and trembles." "My dear Princess, he has but to push up the trapdoor from beneath, and the cross, being tied to the trapdoor, is promptly moved out of his way. Failing this expedient, he can always come out of the cave by the other opening, through which I entered. If this Thragnar has any intelligence at all and a reasonable amount of tenacity, he will presently be at hand." "Even so, he can do no harm unless we accept a present from him. The difficulty is that he will come in disguise." "Why, then, we will accept gifts from nobody." "There is, moreover, a sign by which you may distinguish Thragnar. For if you deny what he says, he will promptly concede you are in the right. This was the curse put upon him by Miramon Lluagor, for a detection and a hindrance." "By that unhuman trait," says Jurgen, "Thragnar ought to be very easy to distinguish." 10. Pitiful Disguises of Thragnar Next, the tale tells that as Jurgen and the Princess were nearing Gihon, a man came riding toward them, full armed in black, and having a red serpent with an apple in its mouth painted upon his shield. "Sir knight," says he, speaking hollowly from the closed helmet, "you must yield to me that lady." "I think," says Jurgen, civilly, "that you are mistaken." So they fought, and presently, since Caliburn was a resistless weapon, and he who wore the scabbard of Caliburn could not be wounded, Jurgen prevailed; and gave the strange knight so heavy a buffet that the knight fell senseless. "Do you think," says Jurgen, about to unlace his antagonist's helmet, "that this is Thragnar?" "There is no possible way of telling," replied Dame Guenevere: "if it is the Troll King he should have offered you gifts, and when you contradicted him he should have admitted you were right. Instead, he proffered nothing, and to contradiction he answered nothing, so that proves nothing." "But silence is a proverbial form of assent. At all events, we will have a look at him." "But that too will prove nothing, since Thragnar goes about his mischiefs so disguised by enchantments as invariably to resemble somebody else, and not himself at all."
