This clay cuneiform tablet, acquired by the Metropolitan Museum of Art in 1886 and dated on paleographic and contextual grounds to approximately the 2nd century BC (Seleucid period), purports to preserve a letter from Sin-sharra-ishkun, the last independent Assyrian king (reigned c. 627–612 BC), to Nabopolassar, founder of the Neo-Babylonian dynasty. The Seleucid date of the physical tablet indicates it is almost certainly a later copy—possibly a scribal exercise or archival reproduction—rather than a contemporary document from the late 7th century BC. Sin-sharra-ishkun and Nabopolassar were bitter adversaries: Nabopolassar led the Babylonian revolt against Assyrian hegemony, and his alliance with the Median king Cyaxares culminated in the destruction of Nineveh in 612 BC, the event that effectively ended the Assyrian Empire. Sin-sharra-ishkun perished during or shortly after that siege. The biblical record intersects this historical moment directly: Nahum's entire oracle announces judgment upon Nineveh, while Zephaniah 2:13–15 envisions Assyria's desolation. The book of Nahum presupposes Nineveh's fall as imminent or accomplished, and 2 Kings 23:29 references Egyptian intervention in the collapsing Assyrian sphere. The tablet does not verify specific biblical passages but materially attests to the political correspondence and diplomatic tensions of the very rulers whose conflict reshaped the ancient Near East and forms the backdrop of late 7th-century biblical prophecy. Interpretation of the tablet's precise content and authenticity as a historical document requires caution given its late copying context.

This Seleucid-era copy of a purported letter between the last Assyrian king and Nabopolassar provides a rare documentary glimpse into the political rivalry that brought about Nineveh's destruction in 612 BC—the very catastrophe proclaimed in the biblical book of Nahum and presupposed across several late 7th-century prophetic texts.
