Whatever your take on religion, it’s hard not to be awed by the magnificent art and architecture created in its name. Think of artists like Michelangelo and Leonardo da Vinci and what likely comes to mind are the ceiling of the Sistine Chapel and The Last Supper. And how can one not be moved standing in the nave of one of Europe’s great cathedrals and staring up into the vast domed ceilings?
One of the earliest forms of artistic expression was the fresco, a technique using pigments to create images on fresh plaster. Frescoes have been around since antiquity but the high water mark for their use paralleled the ascent of Christianity in Europe.
The use of small pieces of glass to create a larger image, the technique of mosaics, has been around even longer. I think of mosaics as the gateway to digital imaging in the sense that creating images with pixels is analogous to creating a mosaic. Below are some images of mosaics and frescoes from a recent journey Turkey and Greece.
