Saggs, H.W.F., The Greatness That Was Babylon, New York and Scarborough: A Mentor Book, 1962
The Greatness That Was Babylon by H.W.F. Saggs is a dense volume that reads like a college textbook for all the good and bad that implies. It has chapters on all different aspects of ancient Mesopotamia to the Babylonian period from history to culture to religion to literature to even mathematics. It goes into great depth into each, but all may not be of interest.
