Hello sun worshippers, Another example of the "round shape on the dial face no matter what the time" discussion:
Almost all of the sundials in the Deutsches Museum "Sundial garden" have circular disks on top of their gnomons. The disks are parallel to the face on which their shadow is read, and yes, their shadows are always round. It is fairly easy to estimate the middle. As an added benefit, especially in public places such as this: the gnomon tip is not easily deformed this way, and what may be more important, the same holds for people bumping into them. I hope the two attached pictures are of some use. One is the polyeder sundial, the other is an inclining and reclining dial with babylonian and italian lines.
