Sundials

Gate of Honour, Caius college, Cambridge.

Collégiale St-Martin. Interesting sun dial / calendar? I think the character at bottom left is a stylised X, so it says 'XII' i.e. 12 noon. When the point of light coming through the disc at the end of the gnomon hits the yellow figure of eight, it's 12 noon local mean time. The month markings enable you to disambiguate the earlier or later crossing of the yellow line the other side of the black centre line. When the sun's high in the sky (July) the shadow is lower than when it's low in the sky (January). I've certainly never seen anything like this before, but have thought about the idea of working the 'equation of time' into a sundial by using the sun's altitude as well as its azimuth.

L'église. Another interesting sundial. // Bergheim, France.

Sundial on schloß wall. The wall faces east, so the sundial only works in the morning.

Sundial on building on Sebalder Platz.

Sundials on Altes Gymnasium stair tower.

Clock and sundial on the Ratstrinkstube inn.
