Diagrams.....................................

Some history professors were fond of dates and chronology and some were just interested in the people and places.  I preferred the latter.  Keeping track of the former was a challenge.  A challenge that Joseph Priestley took up in 1769.  On the diagram below, the horizontal represents the passage of time, the vertical signifies what country we are considering.  For instance, the very upper right hand corner covers the history of the Americas, which would be why there is not so much there.  Not sure exactly how large Priestley's New Chart of History was, however, the right hand column details 106 separate locations.  To be legible, it must have covered a sizable portion of a wall.  A careful reader will note that Priestley dedicated his map to Ben Franklin.
