The Great Pyramid of Giza was finished around 2560 BCE. Cleopatra died in 30 BCE, about 2,500 years later. Only some 2,050 years separate her from us. She lived closer to the Moon landing than to the pyramid's construction. To her, too, it was an ancient monument.
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.
