What were Galileo's balls made of?

4. I think it is safe to...

...to say he would have been familiar with the game:

"An Historical Look. Throwing balls toward a target is the oldest game known to mankind. As early as 5000 B.C. the Egyptians played a form of Bocce with polished rocks. Graphic representations of figures tossing a ball or polished stone have been recorded as early as 5200 B.C."

Having said that he most likely would have also made spheres out of varying materials in order to understand how/if material characteristics affected the results.

Peculiar question... but interesting. I did not realize how far back that type of entertainment went. Would have never guessed it would be that far.
