Print showing the predicted track of the Moon's shadow acros England during the total solar eclipses that occurred in 1715 and 11 May 1724. Printed as a broadsheet, the engraving was produced during the 1720s by John Senex a London engraver and globe makers. The map was printed to encourage people to observe the forthcoming eclipse. Dr Edmond Halley, best known for his comet, wanted to refine the eclipse predictions. This was to be done by noting which people saw a total eclipse acros a wide part of England, both inside and out of the predicted path of the totality. Results collected showed that the calculated path was twice as wide was observed.
