What Sign O'Clock Is It?

An astrolabe.

This is a smallish astrolabe. It comes from 17-century Iran. What is it good for, you ask? Well, you can tell time with it. You can also use it for astrology: it will show you what star sign your planet is in, or something. We're sure this was useful at some point. Or not.

Write a caption! And send more pics!
