I find it curious that nobody chose to respond to, or comment on, the instruments illustrated in the book Kunstuhrmacher in Alt Augsburg
I put images online at: http://www.twigsdigs.com/sundials/kunstuhrmacher/kunstuhrmacher.htm These instruments had to be expensive, and since there seem to be a few surviving, somebody must have purchased and used them. I have a l lot of questions. How were these instruments used? Were they to be used in sunlight? If not, what was the gnomon for? How and why did the single hand indicate the hours from VI to VI? What happened at night? Two of them have the sundial-style line and curves to indicate declination/astrological sign. How did this work? Is it possible that these instruments were so early that the makers gave them the appearance of sundials to give the impression of accuracy to users who previously knew only sundials as time keepers? The first instrument illustrated is the only horizontal one and it appears to have been photographed from the north. It also has a dial (the left one) divided into eight segments with engraved illustrations and Latin text I wonder what that's about Until seeing these photographs I didn't know such things existed.
