Dear sundial friends,
came across an interesting moon dial which is quite different from all the
other moon dials I did see up to now (
<https://kabinett.mapublishing-lab.uni-koeln.de/objekte/monduhr> ).
However: I cannot read it, neither do I understand the way they calculated
the lines on the dial to (may be) read off the time.
The dial does not have the usual numeric list where you can determine the
age of the moon with the aid of the size of the illuminated moon. The age
of the moon, i.e. the angle between moon and sun is needed to determine
time using the moon shadow on a sun dial at night.
How do you read this dial and what is the basis (theory) for the lines to
read of the time on this dial? Is there someone who can help? I would be
very thankful for any help or advice.
Thank You for Your help!
Regards
Siegfried Netzband
