This sheet is a mixture of geometrical and geographical data predicting the 1737 eclipse. It is one of the most elaborate of the contemporary eclipse maps, with the entire blank area around the map given over to scientific data. The data includes detailed calculations for the path and appearance of the eclipse, with particular drawings (and tables) for London, Paris, Dublin and Edinburgh, and smaller diagrams for Aberdeen, York, Amsterdam and Madrid. The central part of the sheet is an angled view of the Eastern Hemisphere overlaid with circles representing the movement of the penumbra.
The earliest advertisement encountered was placed in the London Evening Post (issue 1383) for 25th — 28th September, 1736, almost as an afterthought, at the end of an announcement for a map of Lesser Tartary which concludes:
“… Sold by John Senex at the Globe over-against St. Dunstan’s Church in Fleet-street. Where may be had, A Map, shewing the Passage of the Penumbra over England, Scotland and Ireland, in the Annular Eclipse of the Sun, that will happen in February next, price 1s. Also the General Construction of the same Eclipse, curiously delineated, price 1s. 6d.“
It was more heavily advertised in early 1737 (as one might expect) as the actual event drew closer.
