In the book " Megalith " published by Wooden Books, archaeologists Robin Heath and his colleagues understand the neolithic people who created Stonehenge understand the cycle of the moon and the sun and the solar eclipse We have knowledge of complicated astronomy, such as doing and concluded that we built Stonehenge based on the astronomical calendar.

It is pointed out that there are many examples where "Pythagorean theorem" is applied to the positional relation between Stonehenge and related structures in the same book. Although the circle itself with stone hanges lined up is not a perfect circle, it is arranged with rope and peg about "83 degree centimeter" Megalithic Yard (megalith yard) "unit, there are multiple cases where Pythagorean theorem holds about.

Furthermore, when examining the positional relationship with Inverness's Druid Temple, Castle Rig Stone Circle, Borrowston Rig etc. which are considered to be related to Stonehenge, it turns out that each draws a right-angled triangle, and ancient people I guessed that Pythagorean theorem was utilized.

Since Stonehenge is thought to have been made in 2000 from 2500 BC to 2000 BC, if the Pythagorean theorem was really applied, the contents of the theorem was applied up to 2000 years earlier than the discovery of Pythagoras It was supposed to have done.

In addition, on the day of longest "day summer " in one year, the sun rises on a straight line connecting the basalt rock called heel · stone which constitutes Stonehenge and the center danishki, and the road extending from Stonehenge (Avenue) points in the direction of the rising sun of the summer solstice, so the connection between Stonehenge and the summer solstice is known. For this reason, Megalith is issued on the summer solstice of June 21, 2018.
