Hi diallists, There is an interesting example of the interior wall dial in Olsztyn (Poland). The dial was designed by Copernicus who lived there for some years. In fact that dial isthe only original Copernicus' instrument which was preserved to our times. T. Przypkowski, the diallist and the astronomy historian proved that the dial was designed for a precise equinox determining.
I know also an example of stained glass dial in Poland. The dial is now in the palace in Wilanow, situated in the southern suburb of Warsaw but the original destination was for the royal castle in the Warsaw. The dial was designed in 1788 in Paris by Jean Francois Richer. Best regards Krzysztof Kotynia
