A fascinating little paper in Brain examines Neurology and psychiatry in Babylon. It's a collaboration by British neurologist Edward H. Reynolds and Assyriologist James V. Kinnier Wilson. The sources they discuss are almost 4,000 years old, dating to the Old Babylonian Dynasty of 1894 - 1595 BC. Writing in cuneiform script impressed into clay tablets, the Babylonians left records that (unlike paper) were inherently durable, so many of them have survived.
