Wedge-shaped clay inscriptions impressed with a reed stylus across ancient Sumer, Akkad, Babylon, and Assyria from the late fourth millennium BCE (Uruk IV period, c. 3200 BCE) through the first century CE. Over half a million excavated tablets preserve the administrative accounts, royal inscriptions, lexical lists, astronomical diaries, incantations, and mythological poems through which the Anunnaki deities are known to modern scholarship.
