Mars Rover Curiosity captured again an interesting artifact on Mars. The latest image shows what appears to be ancient petroglpyphs engraved in a rock.
Petroglyphs (also called rock engravings) are pictogram and logogram images created by removing part of a rock surface by incising, picking, carving, and abrading.
Petroglyphs are sometimes easily defined based on the culture, religious beliefs, mythologies, and legends of an ancient civilization placed on rock formations for their descendants.
Many ancient petroglyphs are thought to represent some kind of ritual language often depicting with the same archetypal symbols.
