Rabies was known in antiquity. It is believed to be referenced in the Mesopotamian Laws of Eshnunna, which were somewhat older than the Code of Hammurabi (about 1770 B.C.). Later, Aristotle wrote in his History of Animals that “dogs suffer from the madness.” Yet it was not until the 19th century that the disease could be diagnosed accurately or efforts were made to combat it through animal control.
