Brill's Encyclopedia of Islam 1913-36, p.923, "Nimrud": "At the present day the site is known only as Nimrud, which so far as I know first appears in Niebuhr (1778, p. 355, 368). When this, now the usual, name arose is unknown; I consider it to be of modern origin. It should be noted that names like Nimrod, Tell Nimrod, etc. are not found in the geographical nomenclature of Mesopotamia and the Iraq in the middle ages, while they are several times met with at the present day."
