Someone wrote last night to ask about the mosaic atop my blog. It’s from Ravenna, the Italian city whose art was the subject of a previous post. The question led me to more surfing, which led me to discover plenty more free images of the patristic era, in the Byzantine Art category at Wikimedia. There’s also new material in the Paleo-Christian category. Dazzling. Perfect for your screen-saver. And it’s all free.
