The mosaics of Ravenna--looking up

Ravenna, back in the day, was the Byzantine capital of Europe. During the 5th and 6th centuries many sacred structures were created and filled with art rendered in tiny shards of colored glass. To see the work and to imagine its creation with primitive hand tools is mind-blowing. The color is as vibrant as the day it was executed and the patterns are full of complex mathematical calculations. Lucky for us modern-day travelers much of the mosaic work still exists more than a dozen centuries after the artists walked on the earth. The churches, baptistries and mausaleums are all open to the public for the cost if a cheap ticket. think I will just let the work speak for itself.
