It is, according to me, a sort of sundial. I see Roman numerals (I,
II, III, IV, V, . . .), and there is a clear difference between day
and night. I suspect that the sphere is empty; it might be a thin
surface and inside (the concave part) may be used for some purpose.
It is just a suggestion!

We have a plaster sphere mounted in a box that is clearly for
measuring
something, but we're not sure what. We've put up some pictures and a
description on the web page above. We decided to turn to this list
to see
if anyone knows the answer to these questions:
Does this have anything to do with geography (e.g. is the meridian
line the
Prime Meridian?), or is it related to something else entirely, such as
geometry or optics, given that the corners are marked with the
words concave
and convex?
When was it likely made?
Thanks,
Helen
