What does astronomer Hawkins think Stonehenge is?

1965, astronomer Hawkins thought Stonehenge was a "computer" for deducing astronomical calendars. According to its calendar, a year is divided into eight solar terms, several of which mark the position where the sun rises when it returns to the north during the summer solstice. From the opposite direction, you can see the sun set from the tropic of Capricorn at the winter solstice. Stonehenge structure includes the arrangement of the moon's rise and fall during the major solar terms. It should be said that Si Tong Hench Ring Stonehenge is a juxtaposition structure of religion, mausoleum and celestial phenomena.
