Layard first identified Nimrud as the site of ancient Nineveh; in fact, it is the site of the Assyrian city of Kalhu, called Calah in the Bible (Genesis 10:11–12). He apparently identified Nimrud with the biblical character Nimrod, who, after founding Babel, “went into Assyria, and built Nineveh” (Genesis 10:11). Layard later moved north to excavate at Mosul, the actual site of Nineveh.
