How Sir Pervivale departed secretly from his brother, and how he loosed a knight bound with a chain, and of other doings. And when this was done they rode into many countries, ever inquiring after Sir Launcelot, but never they could hear of him; and at the last they came to a castle that hight Cardican, and there Sir Percivale and Sir Aglovale were lodged together. And privily about midnight Sir Percivale came to Aglovale’s squire and said: Arise and make thee ready, for ye and I will ride away secretly. Sir, said the squire, I would full fain ride with you where ye would have me, but an my lord, your brother, take me he will slay me. As for that care thou not, for I shall be thy warrant.
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. B............
