Born around 3300 BCE, wedge-shaped writing recorded a dozen languages, from Sumerian to Old Persian. The last known dated tablet, an astronomical almanac, comes from around 75 CE. Over 3,300 years of use: longer than our Latin alphabet has existed so far, at roughly 2,700 years.
Around 2300 BCE, Enheduanna, daughter of King Sargon of Akkad, became high priestess of the Moon god at Ur. She composed hymns to the goddess Inanna and put her name to them. She is the oldest person identified as the author of a literary work, about 1,500 years before Homer.
Squeeze Earth's 4.5 billion years into a single 24-hour day. Homo sapiens shows up around 11:59:54 p.m., roughly six seconds before midnight. All of written history, from Sumerian tablets to today, fits into the final tenth of a second. A cosmic blink.
