Document Summary
Spiral designs line the walls and cover the boulder, which is at the front of the entrance. Sunlight travels through the passageway, reaching a tomb at the end. Alignment of the tomb likely reflects a belief of rebirth/reincarnation. 2: at the noon of the solstices and equinoxes, the sundagger exhibits two beams of sunlight which either bisect or frame the spirals. This makes the spring equinox, the summer solstice, the fall equinox and the winter solstice. It is aligned to the summer solstice sunrise. The sun rises behind the heel stone: when it was built, the summer solstice rose beside the heel stone (due to procession of equinoxes). This suggests that there used to be 2 heel stones which framed the solstice sunrise. 5: due to the earth"s 24 hour eastward spin around it"s polar axis, the sun moves westward across the sky; it rises in the east, reaches its highest point at noon, then sets in the west.
