X-rated church art. One of a series of mosaic figures personifying the seasons, the earth, the sea and wisdom, this portrayal of summer (identified in Greek at upper left) decorates the floor of the southern aisle of the recently excavated basilica in Petra, Jordan. Dated to the sixth century, based on the style of the mosaics, this church shows that Christianity flourished in Petra for two centuries longer than previously thought.
