Dear John Thank you for the news - this is a fine discovery.
Frankly speaking I cannot imagine looking directly into the Sun without loosing my sight. Even through these two tiny pine-holes. Whouldn't it be easier and of cource more healthy to hold one's hand near the lower hole (I don't know the right term for these) and find a position when one gets a single spot of lite on it? Well, perhaps not easier but at least you still have eyes to check the time. I must confess: I have never tried to figure out how quadrants work and thus the idea of using them as sundials is quite new to me. -- Best regards Darek Oczki 52N 21E Warsaw, Poland GNOMONIKA.pl Sundials in Poland http://gnomonika.pl --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
