Hello. My brother recommended your Arthur book Winter King a couple of years ago. I've been hooked on your Dark Ages stories ever since. I visited Stonehenge for Summer Solstice 2008 where I had an amazing experience. When I returned home I was delighted to find you had written a novel about Stonehenge. I'm reading it now and I have a question about the building of the Sky Temple, in the early part of the story - the first 4 stones. I'm having trouble visualizing the layout. 1. Gilan lays a nettle string along the line of midsummer's rising, through the center of the temple, and on to the southeastern bank. Wouldn't Gilan's string begin on the eastern side (Midsummer's rising?) and end up on the western bank? 2. Galeth fashions a right angle tool, so they can lay a string across the sun string, and the new string marks the north and south boundaries of the moon's path. But Gilan wants 2 parallel strings, one pointing north and the other south. Wouldn't they both be pointing north and south? Why wouldn't one do? 3. The 4 small stones will be placed on the bank ends of the 2 lines. Is that the 2 moon lines that run north and south? It says, one of each pair of stones would be a pillar and the other a slab. By standing beside the pillar and looking across the opposite slab, the priest could see where the moon rose and where she was on her journeying. Did the 4 stones form a very long, thin rectangle? Where did they place the slab - one the ground, balanced on the pillar or what? Please forgive these detailed questions. I love your writing - wonderful storytelling, character development, rich detail, and vivid descriptions. Can you maybe provide a little sketch with compass points or something?
