About this source

What it is

This is a ten-sided clay prism from Nineveh, dated to 643 BCE, inscribed with cuneiform writing. It records Ashurbanipal's longest surviving inscription and is now kept in the British Museum.

Why it matters

The prism tells, in the king's own voice, about his education, his campaigns in Egypt, his war against his brother Shamash-shum-ukin, and the destruction of Elam. It is a rare case of a ruler's own narrative of his rule surviving directly from his time, showing how Assyrian kings used writing to shape how they would be remembered.

Look closer

  • Why might a king choose to record his own victories and achievements rather than let others write about him?
  • What does the choice to inscribe this text onto a durable clay prism suggest about its intended audience?
  • What might be missing from a king's own version of events like a civil war against his brother?
