Archeological Museum in Granada

This carving in the rocks is thought to be 30-40 thousand years old

Another view of this incredible image which is more interesting as
the person is represented in a stylized manner

The Moors were great Astronomers, Mathematicians and Navigators
I took this picture of the sign for the Astrolab below so that I would remember
the details but now I cannot quite read it. I think the Astrolab dates from a late 1400s

By any measure this Astrolab is a beautiful and accurate piece of machinery
