Byzantine Monuments of Thessaloniki / The Rotunda:
The mosaic from the central dome of the Rotunda (4th century A.D), and a view of it from the ground with the surrounding scaffolds.
And now for a public announcement:
I took both pictures from the same spot with two different lenses. Whenever I am at an archaeological site or museum I always follow the strict guidelines of how a visitor should behave- which means I won’t take any photographs if that’s not allowed. Quite often I use a lot of photoshop to correct the perspective distortion that might occur when shooting mosaics and distant objects from less convenient angles.
So whenever you find yourself in an archaeological site, or museum, never engage in risky and/or unacceptable behaviour- towards yourself and the artifacts- to take a pretty picture.
