ACCAD, or ACHAD, one of the five cities in "the land of Shinar," or Babylonia, said (Gen. x. 10) to have been built by Nimrod. Their situation has been much disputed. Without giving the details of the question, it is sufficient to say that Colonel Taylor, the British resident at Baghdad, who has given much attention to the subject, has, with great probability, identified the ancient Acharad (or Achar, as it is given in some Hebrew MSS.), with the remarkable pile of ancient buildings called Akker-koof, in Sittacene, and which the Turks know as Akker-i-Nimrood and Akker-i-Babil. Akker-koof is about nine miles west of the Tigris, at the spot where that river makes its nearest approach to the Euphrates. The heap of ruins to which the name of Nimrod's Hill—Tel-i-Nimrood, is more especially appropriated, consists of a mound surmounted by a mass of brick-work, which looks like either a tower or an irregular pyramid, according to the point from which it is viewed. It is about 400 feet in circumference at the bottom, and rises to the height of 125 feet above the sloping elevation on which it stands. The mound, which seems to form the foundation of the pile, is a mass of rubbish accumulated by the decay of the superstructure. In the ruin itself, the layers of sun-dried bricks, of which it is composed, can be traced very distinctly. They are cemented together by lime or bitumen, and are divided into courses varying from 12 to 20 feet in height, and are separated by layers of reeds, as is usual in the more ancient remains of this primitive region. The use of this remarkable monument has been a subject of doubt and conjecture. The embankments of canals and reservoirs, and the remnants of brick-work and pottery occupying the place all around, evince that the Tel stood in an important city; and, as its construction announces it to be a Babylonian relic, the greater probability is that it was one of those pyramidal structures erected upon high places, which were consecrated to the heavenly bodies, and served at once as the temples and the observatories of those remote times.
