An interesting exhibition displaying many historical views of the Earth, be that flat or round. Potentially useful for wiki articles because look at all these pretty pictures!

This is really great stuff, and a very fascinating look at the history of our own attempts to quantify observable phenomena.  (sorry for the necro, thought I'd posted here already and just wanted to thank PP for collecting this info.)
