I read in a Turkish newspaper, Aksam, that one of the mosaics in Hagia Sophia was cleaned to reveal the face of the angel Seraphim. According to the news article, the mosaic has been covered for about 160 years. Possibly because of this, the pieces of the mosaic are preserved exceptionally well. This is exciting news for art historians and art lovers around the world. It is particularly exciting for me as I was probably within touching distance from the beautiful face when I was up on the scaffolding a month ago.
As soon as I saw the photo of the mosaic I thought of photographic techniques that allow photographing a 360-degree picture of a human head spread on the two-dimensional surface. In time, perhaps I will try to wrap this mosaic photograph on a 3-D head to see how well it will map. The following is an example of such a photograph.
