Sennacherib's Prism

Corroborates the biblical account of Sennacherib's siege of Jerusalem (2 Kings 18–19) and uniquely confirms Hezekiah as a historical king paying tribute to Assyria.

Sennacherib's Prism is a six-sided clay cylinder about 38 centimeters tall. It is covered with small, neat cuneiform script arranged in columns running down each face. The text records eight military campaigns carried out by the Assyrian king Sennacherib, who ruled from 705 to 681 BCE. The prism was produced in 689 BCE near the end of his reign and was likely meant to be buried in the foundations of a building as a royal record.

Colonel Robert Taylor, a British diplomat serving in Baghdad, discovered the prism in 1830 near the ruins of Nineveh in what is now northern Iraq. He acquired it at Kouyunjik, the main mound of ancient Nineveh. Taylor brought it to Britain, and after his death it passed through several hands before being purchased by the British Museum in 1855. A second nearly identical prism, known as the Oriental Institute Prism, was discovered later and is now in Chicago. Both texts record the same campaigns with only small differences in wording.

The clay was shaped into a six-sided form and the cuneiform text was pressed into the surface while the clay was still soft. The prism was then baked hard to preserve it. This type of object is known as an annalistic prism, a standard format used by Assyrian kings to summarize their military achievements.

The third campaign recorded on the prism covers Sennacherib's invasion of Judah around 701 BCE. The text names 46 Judean towns captured and claims that 200,150 people were taken prisoner, though many scholars believe this figure may be exaggerated or based on a different counting system. The prism specifically names Hezekiah, king of Judah, as a ruler who did not submit and describes him as shut up in Jerusalem like a bird in a cage. The text then records that Hezekiah eventually sent tribute to Sennacherib in Nineveh, including gold, silver, ivory, and other valuables.

What the prism does not say is equally important. It never claims that Sennacherib captured Jerusalem. Assyrian royal inscriptions almost always boasted of capturing enemy cities, so the absence of any claim about Jerusalem is a significant detail. The prism says Sennacherib made the city smaller and increased the tribute Hezekiah owed, but it does not describe a conquest.

Both the Taylor Prism in the British Museum and the Oriental Institute Prism remain in excellent condition. The script is clear and readable, and scholars have been able to translate the text fully. Both objects are on permanent public display and are among the most visited ancient artifacts in their respective museums.

• The prism names Hezekiah, king of Judah, as a historical figure who paid tribute to Sennacherib, making it one of the few non-biblical texts to confirm a Judean king by name
• The 701 BCE campaign against Judah is described in detail, including the capture of 46 cities and the siege of Jerusalem
• The text uses the phrase 'like a bird in a cage' to describe Hezekiah shut up in Jerusalem, but never claims the city was taken
• Hezekiah's tribute is listed as 30 talents of gold and 800 talents of silver, closely matching the figures in 2 Kings 18:14
• The prism was produced in baked clay using cuneiform script, the standard writing system of ancient Mesopotamia
• Two nearly identical prisms survive, one in London and one in Chicago, allowing scholars to compare the texts and confirm their accuracy
• The absence of a claim of conquest over Jerusalem is a major point of scholarly discussion and broadly supports the biblical account of Assyrian withdrawal

The prism connects directly to 2 Kings 18 and 19, which describe Sennacherib's invasion of Judah and siege of Jerusalem. Second Kings 18:13 states that in the fourteenth year of Hezekiah, Sennacherib came against all the fortified cities of Judah and took them. This matches the prism's claim of capturing 46 Judean towns. The tribute payment in 2 Kings 18:14 lists 30 talents of gold and 300 talents of silver, very close to the prism's figures. Isaiah 36:1 gives the same event with nearly identical language, confirming the account appears in two independent biblical sources. The most striking connection is what both the prism and the Bible agree did not happen. The Bible describes the Assyrian army leaving Jerusalem after an angel of the Lord struck down 185,000 Assyrian soldiers (2 Kings 19:35). The prism ends its account of Jerusalem without claiming victory over the city. Isaiah 37:33 records God's word that Sennacherib would not enter Jerusalem, and the prism's silence on a conquest aligns with this outcome. Second Chronicles 32:1 also records Sennacherib's invasion and Hezekiah's response, describing the Judean king strengthening Jerusalem's defenses, which is consistent with archaeological evidence from Hezekiah's tunnel and walls discovered in the city.
