Dear Maciej and Sara, Gosh. Those are really incredible dials. The Nested L-shapes of the chapter rings on the Jacques Le Marie dial are very cleverly set out. I wonder how big a market there was for this kind of dial!
Maciej's description of a Nuremberg Diptych - The shadow was cast by the edges of the upper leaf of the dial - is quite close to what I have in mind. This would be fine in British Latitudes but as you move nearer to the equator you find yourself having to peer inside an ever-narrowing gap! Very best wishes Frank --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
