Re: How would this sundial work?

There is more of a description of that dial at
http://www.diduknow.info/sun/san6.html#.  It is a horizontal dial of which
the gnomon has been broken off.  It is for use during daytime and at night.
 I presume the rotating plate allows adjustment for telling time by the
moon, depending where the moon is in its ~30 day synodic period.

Hello All,

 

I came across a picture of a sundial this morning that I found to be
confusing. See the dial picture on the following web page - it has a
vertical post gnomon and the dial plate looks like it might be designed to
rotate about the center:

Have any of you seen this dial before and do you have any ideas how it might
work?

How would this sundial work?

[J. Tallman]

Hello All,

 

I came across a picture of a sundial this morning that I found to be
confusing. See the dial picture on the following web page - it has a
vertical post gnomon and the dial plate looks like it might be designed to
rotate about the center:

 

http://www.diduknow.info/sun/san5.html#

 

Have any of you seen this dial before and do you have any ideas how it might
work?

 

 

Best,
