As with its companion, Wright’s “General Construction of a Solar Eclipse”, the map was first advertised in the London Evening Post (issue 1383) for 25th — 28th September, 1736, the announcement ending:
“… 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.“
Senex started advertising the map more heavily in January 1737, seemingly a straightforward commercial response to George Smith’s rival delineation of the eclipse, touted as “A Method vastly superior to any Thing of the like Nature yet attempted, and probably the last Improvement that can ever be made to Solar Eclipses”. Wright, however, was less pragmatic, and got into an heated public row with Smith and his publisher Edward Cave, accusing Smith of plagiarism and incompetence, with Smith replying in similar vein, much of this conducted in the correspondence pages of the Grub Street Journal, a contemporary satirical magazine. While charge and countercharge were long-winded (with both seemingly also contributing under pseudonyms), Wright did claim that this map was originally published nine months earlier, counting back from mid-January, so perhaps mid-May (if he can be trusted on this point).
