"I would like to offer a model of 'night-time reader of solar time' contained behind zodiac symbols on the ceiling of an Egyptian temple. Due to the 100 AD date of the Dendra temple, the origin of this double dial Ursa Major star clock (with zero included at the proper 7pm position and the second dial - the first dial being of 12 hour construction, with zero orienting north - as Peter Lancaster Brown and Charles Whitney describe as mandatory for all north hemisphere solar star clocks) is clouded. Babylonians may have recommended this double dial form, and Greeks and Egyptians may have over-written a pure earlier solar time keeping method with mystical zodiac symbols."
