Ear piercing is one of the oldest known forms of body modification, with artistic and written references from cultures around the world dating back to early history. Gold earrings, along with other jewelry made of gold, lapis lazuli, and carnelian were found in the ancient sites in Lothal, India, and Sumerian Royal Cemetery at Ur from the Early Dynastic period. Gold, silver and bronze hoop earrings were prevalent in the Minoan Civilization (2000–1600 BCE) and examples can be seen on frescoes on the Aegean island of Santorini, Greece. During the late Minoan and early Mycenaean periods of Bronze Age Greece hoop earrings with conical pendants were fashionable. Early evidence of earrings worn by men can be seen in archeological evidence from Persepolis in ancient Persia. The carved images of soldiers of the Persian Empire, displayed on some of the surviving walls of the palace, show them wearing an earring.
