A time-exposure image shows the rotating sky in form of star trails around the north celestial pole (marked by the north star Polaris). On the Earth is a prehistoric rock art in the remote valley of Teimareh in central Iran. The valley is home to thousands of ancient petroglyphs, dating from 4500 to 17000 years ago, one of the world's most important petroglyph sites, still largely undiscovered. This picture might represent an imaginary winged man which is surprisingly similar to some pictures engraved by other prehistoric rock artists across the planet, as far as the Yellowstone National Park in the North America.
