The Circus in Bath is the same size as Stonehenge. It was designed by John Wood, a practising Druid, and the architect of Georgian Bath. It has exactly 33 houses, some of unequal size, in three curved blocks of equal size. There are 3 roads going into The Circus, at equal intervals.
Above the doors, there is a continuous frieze of stone carved symbols going all the way round. I would estimate there are over 900 symbols. There seems to be no repeating pattern to the symbols. Some are vaguely repeated, but most seem different. There is an hourglass, a heart with arrows, a serpent, dragon, rose.
The book, The Northern Lights, by Philip Pullman has a picture on the front cover of an alethiometer. This was called The Golden Compass, when it was made into a film. The alethiometer looks like a pocket version of The Circus. Or maybe The Circus is a giant size version of the alethiometer. The alethiometer symbols are the same sort of thing as The Circus symbols. The alethiometer has 36 symbols which corresponds to 33 houses plus 3 roads.
The fictional alethiometer is used to find out the truth. You can use its three equidistant control dials to set three needles to point at three symbols whilst asking a question. You then let the free needle do what it needs to do, and the answer appears. But only if you can read it! The needle sets itself at different symbols for different times to convey its answer. Each symbol has about 40 different meanings, some of higher priority than others.
This method of determining the truth reminds me of how dowsing works, though dowsing is more primitive, based on asking questions which give a yes or a no answer. Dowsing has been long practised around the world, including recently in the UK (the Scillies, for example) to find water, with 100% success. A dowsing rod is a bit like a compass needle, loosely held in the hand so that you do not force the rod to move, nor do you hold it back. You just allow it to move if it wants to. Dowsing can be used to find things other than water, such as gold, or earth energy lines.
Back to The Circus. It has the symbols. It is a circle in three parts. It was built by a Druid in times when Bath was considered the metropolitan home of Druidry in the UK (1768). In the centre of The Circus there was once a “well”. A built hole in the ground. Somewhere where you could have put the stem for a needle or two or three or four, a bit like the centre of a compass, a bit like a dowsing rod. Loosely fitted so that it can swing by itself. The water below may have helped the divine energy flow through the needle.
So it seems to me that The Circus was a centre for finding out the truth using the same energies that modern dowsers use to find water and other things. Just much much more sophisticated.
