Now her passion waxing ever more ardent for Bertrand, as she learned that he was grown a most goodly gallant, tidings reached her that the King of France, in consequence of a tumour which he had had in the breast, and which had been ill tended, was now troubled with a fistula, which occasioned him extreme distress and suffering; nor had he as yet come by a physician that was able, though many had essayed, to cure him, but had rather grown worse under their hands; wherefore in despair he was minded no more to have recourse to any for counsel or aid. Whereat the damsel was overjoyed, deeming not only that she might find therein lawful occasion to go to Paris, but, that, if the disease was what she took it to be, it might well betide that she should be wedded to Bertrand. So--for not a little knowledge had she gotten from her father--she prepared a powder from certain herbs serviceable in the treatment of the supposed disease, and straightway took horse, and hied her to Paris. Arrived there she made it her first concern to have sight of Bertrand; and then, having obtained access to the King, she besought him of his grace to shew her his disease. The King knew not how to refuse so young, fair and winsome a damsel, and let her see the place. Whereupon, no longer doubting that she should cure him, she said:--"Sire, so please you, I hope in God to cure you of this malady within eight days without causing you the least distress or discomfort."

Whereupon the King said to himself:--"Perchance she is sent me by God; why put I not her skill to the proof, seeing that she says that she can cure me in a short time, and cause me no distress?" And being minded to make the experiment, he said:--"Damsel, and if, having caused me to cancel my resolve, you should fail to cure me, what are you content should ensue?" "Sire," answered the damsel, "set a guard upon me; and if within eight days I cure you not, have me burned; but if I cure you, what shall be my guerdon?" "You seem," said the King, "to be yet unmarried; if you shall effect the cure, we will marry you well and in high place." "Sire," returned the damsel, "well content indeed am I that you should marry me, so it be to such a husband as I shall ask of you, save that I may not ask any of your sons or any other member of the royal house." Whereto the King forthwith consented, and the damsel, thereupon applying her treatment,
