""I really like the chart, but not in this article Jeff Dahl ""

""Could you explain why? It is one of the most influential and popular works JP published. Awadewit | talk ""

Yes the work was influential. That is why we have the sentence: ""The trustees of Warrington were so impressed with Priestley's lectures and charts that they arranged for the University of Edinburgh to grant him a Doctor of Law degree in 1764.""  You could even say ""...impressed with Priestley's Lectures on History: A Chart of Biography and A New Chart of History that they arranged..."" Keeping the image is okay, but I would cut down the prose.  

But that sentence doesn't really demonstrate the work's influence. Priestley's degree is not really important at all. 

Priestley also designed visual study aides for his Lectures on History: A Chart of Biography (1765)[26] and A New Chart of History (1769).[27] According to Priestley, they ""impressed"" upon students ""a just image of the rise, progress, extent, duration, and contemporary state of all the considerable empires that have ever existed in the world"".[28] Both charts had accompanying prose descriptions and were popular for decades—A New Chart of History had gone through fifteen editions by 1816.[29] The trustees of Warrington were so impressed with Priestley's lectures and charts that they arranged for the University of Edinburgh to grant him a Doctor of Law degree in 1764.[30]

There are currently four sentences on the charts - one introducing them, one explaining them, one detailing their reception, and one providing a conclusion/transition of sorts. What about this new version?

""Priestley also designed two Charts to serve as visual study aides for his Lectures on History, which ""impressed"" upon students ""a just image of the rise, progress, extent, duration, and contemporary state of all the considerable empires that have ever existed in the world"". Both charts were popular for decades and the  The trustees of Warrington were so impressed with Priestley's lectures and charts that they arranged for the University of Edinburgh to grant him a Doctor of Law degree in 1764.""  | talk "
