6 hexagrams and 12 zodiacal signs and glyphs appear on a mosaic ceiling at Greenwich Town Hall, London, England, right above the main door. It is not clear what these hexagrams are doing there and if the number six has a certain meaning. I can only guess that it has to do with the influence of alchemy. Anyhow it’s a splendid contribution to my new research about the hexagram and the Zodiac.
