Eclectic Perambulations in the Noosphere
"Lalibela in Ethiopia is the home of eleven churches, hewn from the rock. The most famous is that of Saint George, which was built in the thirteenth century. As demonstrable a point as you can get that Africa was not the ‘dark continent’ many suppose until the arrival of Europeans, it shows that technology there was virtually on a par with that of the western world. The site is a UNESCO world heritage center and has often been referred to as the eighth wonder of the world."

"Yes, but how many dark clouds have a multicolored lining? Pictured, behind this darker cloud, is a pileus iridescent cloud, a group of water droplets that have a uniformly similar size and so together diffract different colors of sunlight by different amounts. The above image was taken just after the picturesque sight was noticed by chance by a photographer in Ethiopia. A more detailed picture of the same cloud shows not only many colors, but unusual dark and wavy bands whose origins are thought related to wave disturbances in the cloud."
