The first thing to understand when discussing mysterious bag carvings is that they don't appear in just a few places, nor in a single region, but literally all over the world. Start in Mesopotamia, where bags appear in the works of the Sumerians, Assyrians, and Babylonians, the Mitanni and Phoenician empires, and the ancient Armenians. Crossing the ocean, bags appear in Mesoamerican works that predate the Aztecs, Mayans, and Incas, including the Olmec and Toltec empires, and the ancient tribes of Veracruz. They appear in Asia, in the works of Hindus and ancient Indonesian tribes.
