What Is the Behistun Inscription and Why Does It Matter?

What Is the Behistun Inscription?

The Behistun Inscription is a massive trilingual cliff carving ordered by the Persian King Darius the Great around 522–486 BCE, and it became the key that unlocked the ability to read cuneiform — a writing system that had been completely undeciphered for nearly 2,000 years.

Where Is It Located?

Carved into a limestone cliff along an ancient trade route in what is now western Iran, the inscription sits approximately 330 feet (100 meters) above the ground near the town of Bisotun, in Kermanshah Province. Its extreme height made it visible to travelers passing below — and nearly impossible to reach, which is precisely what preserved it so well over the centuries.

What Does the Inscription Say?

The Behistun Inscription records the military victories and divine authority of Darius the Great, who ruled the Achaemenid Persian Empire. It declares how he suppressed rebellions, defeated rival claimants to the throne, and ruled by the grace of the god Ahura Mazda. The same text was written in three languages: Old Persian, Elamite, and Babylonian (a dialect of Akkadian). This trilingual format is exactly what made it so historically significant — it functioned much like the Rosetta Stone did for Egyptian hieroglyphs.

Who Decoded It and How?

British army officer and scholar Henry Rawlinson is credited with deciphering the inscription in the 1830s and 1840s. He first copied the Old Persian sections by scaling the cliff face with ropes and ladders — a genuinely dangerous undertaking. The Babylonian portion was even more inaccessible, carved on a separate panel across a deep recess in the rock. To copy it, Rawlinson reportedly employed a local Kurdish boy who swung on ropes to make paper casts of the text.

Because Rawlinson already had some knowledge of Old Persian, he used that section as his starting point. By working across all three languages and cross-referencing them, he was able to crack the cuneiform script systematically. His findings were published in the late 1840s and confirmed by other scholars shortly after, establishing the decipherment as one of the great intellectual achievements of the 19th century.

Why Did It Rewrite History?

Before cuneiform was decoded, entire civilizations were essentially silent. The Assyrians, Babylonians, Sumerians, and Akkadians had left behind hundreds of thousands of clay tablets — but no one could read them. The decipherment of cuneiform through the Behistun Inscription suddenly opened up 2,000 years of recorded human history: royal annals, religious hymns, legal codes (including the famous Code of Hammurabi), astronomical records, and epic literature like the Epic of Gilgamesh.

In a very real sense, unlocking Behistun gave humanity access to the earliest chapters of its own written story.

How Is It Preserved Today?

The Behistun Inscription was designated a UNESCO World Heritage Site in 2006. While erosion and past damage from World War II-era soldiers using the relief carvings for target practice have taken a toll, ongoing preservation efforts continue. The site remains one of the most important archaeological landmarks in the world.
