The interesting thing about a knot is its formal complexity. Even the simplest pedigree knot, the trefoil, with its three roughly symmetrical lobes, has mathematical as well as artistic beauty. For the religious, Kind Solomon's knot is said to embody the essence of all knowledge. For carpet makers and cloth weavers all over the world, the challenge of the knot lies in the rules of its surprises. Knots can change but they must be well-behaved. An informal knot is a messy knot. Louise and I were held by a single loop of love. The cord passing round our bodies had no sharp twists or sinister turns. Our wrists were not tied and there was no noose about our necks. In Italy in the fourteenth and fifteenth centuries a favourite sport was to fasten two fighters together with a strong rope and let them beat each other to death. Often it was death because the loser couldn't back off and the victor rarely spared him. The victor kept the rope and tied a knot in it. He had only to swing it through the streets to terrify money from passers-by. I don't want to be your sport nor you to be mine. I don't want to punch you for the pleasure of it, tangling the clear lines that bind us, forcing you to your knees, dragging you up again. The public face of a life in chaos. I want the hoop around our hearts to be a guide not a terror. I don't want to pull you tighter than you can bear. I don't want the lines to slacken either, the thread paying out over the side, enough rope to hang ourselves. I was sitting in the library writing this to Louise, looking at a facsimile of an illuminated manuscript, the first letter a huge L. The L woven into shapes of birds and angels that slid between the pen lines. The letter was a maze. On the outside, at the top of the L, stood a pilgrim in hat and habit. At the heart of the letter, which had been formed to make a rectangle out of the double of itself, was the Lamb of God. How would the pilgrim try through the maze, the maze so simple to angels and birds? I tried to fathom the path for a long time but I was caught at dead ends by beaming serpents. I gave up and shut the book, forgetting that the first word had been Love. In the weeks that followed Louise and I were together as much as we could be. She was careful with Elgin, I was careful with both of them. The carefulness was wearing us out. One night, after a seafood lasagne and a bottle of champagne we made love so vigorously that the Lady's Occasional was driven across the floor by the turbine of our lust. We began by the window and ended by the door. It's well-known that molluscs are aphrodisiac, Casanova ate his mussels raw before pleasuring a lady but then he also believed in the stimulating powers of hot chocolate. Articulacy of fingers, the language of the deaf and dumb, signing on the body body longing. Who taught you to write in blood on my back? Who taught you to use your hands as branding irons? You have scored your name into my shoulders, referenced me with your mark. The pads of your fingers have become printing blocks, you tap a message on to my skin, tap meaning into my body. Your morse code interferes with my heart beat. I had a steady heart before I met you, I relied upon it, it had seen active service and grown strong. Now you alter its pace with your own rhythm, you play upon me, drumming me taut. Written on the body is a secret code only visible in certain lights; the accumulations of a lifetime gather there. In places the palimpsest is so heavily worked that the letters feel like braille. I like to keep my body rolled up away from prying eyes. Never unfold too much, tell the whole story. I didn't know that Louise would have reading hands. She has translated me into her own book. We tried to be quiet for Elgin's sake. He had arranged to be out but Louise thought he was at home. In silence and in darkness we loved each other and as I traced her bones with my palm I wondered what time woulJeanette Winterson is the author of 'Written On The Body', published 1993 under ISBN 9780679420071 and ISBN 067942007X.
