Claude, We had an article on how to construct a reflected dial in a recent issue of our journal Compendium.
If you're looking for info on existing reflected dials, see the October 1990 issue of the Bulletin of the British Sundial Society. >From that article by R.R.J.Rohr - 3 dials in France: The best known reflected dial is at the Lycee Stendhal in Grenoble. It covers walls and ceiling, including lines for a large variety of info. The basilica of Saint-Antoine-en-Vienne (40 km west of Grenoble) has a reflected dial in the winding stairs of a tower. A similar dial in the Gothic church steeple in Saint-Sauvuer-la- Foucardiere, near Chatellerault He also mentions the Gallery of the Astrolabe - and notes that visitors are welcome. In the July 1991 issue of the Bulletin, there is also mention of two relected dials in an Italian monastery at Montinengo in Bergamo. Fred Sawyer North American Sundial Society.
