from which to begin. So I looked again at the paper, read again every word of the surrounding area: to the south, the Burgi Stacks, the cave, then the Seat of Mandrup and Sheep Pund to the north. Just east was the Green of Mandrup, the field behind me.
And then I saw it. Almost completely hidden by those words â âGreen of Mandrupâ â but just protruding from behind the letters on either side, was a solid, straight line: a fence. And as it reached the cliff, it corresponded with the parallel. I stood and faced east, following the posts that ran through the field and up the hill, and then looked back to where the fence ended in a muddle of wire and wood hanging over the cliff edge. So this was it: sixty degrees north of the equator. This was my starting line.
Geography begins at the only point of which we can be certain. It begins inside. And from there, from inside, rises a single question: where am I?
Imagine yourself stood upon a hill. Or better, imagine yourself stood on a tall hill on a small island, the horizon visible in every direction â a perfect, unbroken line. From early morning until late in the night you stand there. You watch the sun rise from one side of the island and arc its way above, moving slowly and predictably through the sky until it reaches the opposite horizon, where it gradually disappears. As the light fades, stars freckle against the mounting darkness. They too turn about you, on an axis rooted at the North Star, Polaris. This great arena of night and day seems to roll over the stationary world and surround you with its movement. And that question rises: where am I?
The universe that we can see is a place of mirrors and illusions, tricks of the eye and the mind, and it takes a great leap of scientific faith to come to terms with the facts as we now know them to be: that nothing is still; that both our universe and our planet are in ceaseless motion. To look upwards and to acknowledge this is to take a nauseating lurch of the imagination. It is to be overwhelmed not just by a feeling of insignificance, but of fear, vulnerability and exhilaration. Amid all this movement, this unfathomabledistance, it seems somehow impossible that we could be anywhere at all.
But our understanding of where we are on the Earth has not been built with this celestial motion in mind. Since people first began to use the sun and stars as navigational aids, they have done so by being ignorant of, or by ignoring such disorientating facts. That the North Star is not a stable point within the universe does not matter so long as it seems to be a stable point. That the sun does not turn around the Earth makes no difference if it continues to appear to do so, and that its appearance is predictable. For the roots of that question â where am I? â are not so much philosophical, nor exactly scientific; they are practical. Where we are only truly makes sense in so far as it relates to where we have been and where we want to be. In order to move in a purposeful way, to avoid wasting our time and endangering our lives, we must build an image of our location, and where we stand in our surroundings. We must make maps.
I stared out at the calm ocean, at the tide lines laced like skeins of white hair. I looked towards the horizon â blue fastened to blue â and beyond, towards unseen places: to Greenland, to North America, to Russia, Finland, Scandinavia and back here again across the North Sea. I looked out for several minutes, then felt ready to go. I turned and walked up the hill, alongside the fence. From my starting line at the cliff I made my way back along the parallel, glad to be moving again.
Soon, the lavish green that had fringed the shore gave way to low heather and dark, peaty ground. The land flattened into a plateau of purple and olive, trenched and terraced where the turf had been cut. White tufts of bog cotton lay strewn about the hill. Shallow pools of black water crouched
