Accad

Concise Bible Dictionary:

Nimrod’s kingdom embraced Babel, Erech, Accad and Calneh in the land of Shinar (Gen. 10:1010And the beginning of his kingdom was Babel, and Erech, and Accad, and Calneh, in the land of Shinar. (Genesis 10:10)). The ruins of Accad cannot now be identified with certainty. In the Assyrian inscriptions however a city is named Akkad, which was doubtless the same, and there is a remarkable mound, some 50 miles N.NW. of Babylon, about 33° 25' N, 44° 15' E, called Akker-koof, and known to the Arabs as Akker-i-Nimrood or Tell-Nimrood.
It is about 400 feet in circumference and 125 feet high, composed of sun-dried bricks, reeds, bitumen. Some believe this to have been the ancient Accad; but others think it must have been farther south.
“The Accadians had been the inventors of the pictorial hieroglyphics, which afterward developed into the cuneiform or wedge-shape system of writing. They had founded the great cities of Chaldea, and had attained to a high degree of culture and civilization.” — Dr. Sayce. An inscription has been found showing the Accadian transition from the hieroglyphic to the wedge-shape letters; and others with the latter interlined with the Babylonian or Assyrian dialect. The Accadian was the principal dialect spoken by the primitive inhabitants of Babylonia, and in which some of their ancient legends are inscribed. It became eventually the learned language of the kingdom, as Latin became in the West.
