And so Sir Percivale rode till it was after noon, and then he came upon a bridge of stone, and there he found a knight that was bound with a chain fast about the waist unto a pillar of stone. O fair knight, said that bound knight, I require thee loose me of my bonds. What knight are ye, said Sir Percivale, and for what cause are ye so bound? Sir, I shall tell you, said that knight: I am a knight of the Table Round, and my name is Sir Persides; and thus by adventure I came this way, and here I lodged in this castle at the bridge foot, and therein dwelleth an uncourteous lady; and because she proffered me to be her paramour, and I refused her, she set her men upon me suddenly or ever I might come to my weapon; and thus they bound me, and here I wot well I shall die but if some man of worship break my bands. Be ye of good cheer, said Sir Percivale, and because ye are a knight of the Round Table as well as I, I trust to God to break your bands. And therewith Sir Percivale pulled out his sword and struck at the chain with such a might that he cut a-two the chain, and through Sir Persides’ hauberk and hurt him a little. O Jesu, said Sir Persides, that was a mighty stroke as ever I felt one, for had not the chain been ye had slain me. And therewithal Sir Persides saw a knight coming out of a castle all that ever he might fling. Beware, sir, said Sir Persides, yonder cometh a man that will have ado with you. Let him come, said Sir Percivale. And so he met with that knight in midst of the bridge; and Sir Percivale gave him such a buffet that he smote him quite from his horse and over a part of the bridge, that, had not been a little vessel under the bridge, that knight had been drowned. And then Sir Percivale took the knight’s horse and made Sir Persides to mount up him; and so they rode unto the castle, and bade the lady deliver Sir Persides’ servants, or else he would slay all that ever he found; and so for fear she delivered them all. Then was Sir Percivale ware of a lady that stood in that tower. Ah, madam, said Sir Percivale, what use and custom is that in a lady to destroy good knights but if they will be your paramour? Forsooth this is a shameful custom of a lady, and if I had not a great matter in my hand I should fordo your evil customs.
