It looks like it may have been a freebie (langiappe) given at a French
sundial society meeting.
Fun
sundial! This is a model of what was a fairly common type of
portable sundial about 200 years ago, but I don't recall the name.
Suspend the dial from a string tied around the elongated slot and
centered over the current month . There is supposed to be a tiny wire
or thin rod, or some other protrusion protruding a little bit from nose
of the engraved sun. Hold the string, and turn the dial so that the
protrusion casts a long shadow, and read the time from where the shadow
crosses the current month line.

Hello People!
I just got a strange little sundial, its a coin, elliptical, about 1"
by 1 3/8", apparently made of sterling silver.
There is a hole through the coin at the sun marker, I assume for some
sort of gnomon to be inserted.
Across the top seems to be the months, and on the back it looks like a
map of Europe with some city markings.

I'd
like to know how to use it, anyone know? I know being so small it will
not be very accurate, especially since I am in the states (approx 31
degrees).
Any help appreciated,
Thanks!
