Cracking The Stone Age Code
Here is a BBC documentary called Cracking The Stone Age Code. It was first aired on October 31, 1970. Professor Alexander Thom asserts his theory that Stonehenge and other megalithic sites were used to record time and predict solar and lunar eclipses.
Host Magnus Magnusson looks at Thom’s evidence and hears what different archaeologists think of the suggestion that Stone Age Britons could make such elaborate calculations. If Thom’s theory is correct, previous archaeological certainties about the knowledge and ability of people in the Stone Age would be overturned.
