It is thought that Hippocrates wrote this about 4-5 BCE. It is mostly advice to traveling physicians. He advised them to firstly always check the air quality of each city they were going to visit Also to observe: winds, water quality, terrain, and personal habits of the citizenry. Did learn a few new vocab words: fenny, meaning boggy. Hippocrates thinks he can evaluate the population of a city based on the above qualities of their environment. Amongst others he evaluates the Scythians, inhabitants of Phasis (eastern shore of the Black Sea), and the Macrocoephali. (long headed people, normally of the head deformation tribes in Africa, but Hippocrates is probably referring to an area in Turkey called Pontus. I had to look this up). This was a copy that came from a packet given to me for additional reading for a class I took 30 years ago. I don't believe it's in its entirety--I'm not sure of the date or who published. Off the shelf! 48 pages (probably more, but the font was only 6-7 and in double columns) ( )
