fort, one of the four cities founded by Nimrod (Gen. 10:10). It is the modern Niffer, a lofty mound of earth and rubbish situated in the marshes on the left, i.e., the east, bank of the Euphrates, but 30 miles distant from its present course, and about 60 miles south-south-east from Babylon. It is mentioned as one of the towns with which Tyre carried on trade. It was finally taken and probably destroyed by one of the Assyrian kings (Amos 6:2). It is called Calno (Isa. 10:9) and Canneh (Ezek. 27:23).
