35 34 caLendar caperS the reasons for the seasons At Stonehenge, in the numbers of stones and their dimensional spacing one repeatedly finds the numbers of the solar year and lunar month. On page 29 we saw that, at Stonehenge, a 512 rectangle defines all eight solar festivals celebrated in our present culture. It also aligns with the extreme positions of the Moon. The 56hole Aubrey Circle suggests the ancient calendar of thirteen months of 28 days a 364 day year. The thirty upright stones of the Sarsen circle suggest the Egyptian calendar of twelve months of thirty days totalling 360 days. More crucially, twenty nine of the uprights were full width and one was deliberately made halfwidth see page 47, stone 11, and top picture, page 23, the smaller stone fifth from the left. Was this an attempt to represent in stone the 29 day lunation cycle the time between two full moons Twice 29.5 makes 59, the number of Y and Z holes and also the number of stones in the bluestone circle. The bluestone horseshoe contained nineteen stones. Why In nineteen years there are exactly 235 lunations a near perfect repeat cycle of the Sun and Moon, called the Metonic cycle. Other close repeat cycles occur after three, five, and eight years. 235 divided by 19 is 12 , the number of lunations full moons in one year. Seven nineteenths is 0.368. The mean Sarsen Circle diameter is 3 x 12.368 MY 100.9 feet and the ratio between the Aubrey Circle diameter and Sarsen Circle outer diameter is also seven nineteenths opposite lower.
