John Senex

1678 - 1740

John Senex was a variously skilled man: a London engraver and cartographer, an astrologer for Queen Anne, a geologist and explorer, he had his book shop in Fleet Street.

He was a friend to the famous astronomer Edmond Halley, who computed the orbit of the comet that bears his name.

According to Encyclopedia Britannica, Senex engraved plates for London almanacs every year from 1717 to 1727 (except 1723); he also created a series of engravings for the second edition of Sir William Browne's Account of Microscopes and Telescopes. But he was famous mainly as a globe and map maker. In 1710 he issued maps of North America and two years later of "Moscovy". On July 4, 1728, he was admitted as fellow to the Royal Society of London, and ten years later read there his paper on "Contrivance to Make the Poles of the Diurnal Motion in a Celestial Globe Pass round the Poles of the Ecliptic." Many of his maps are in museums and libraries, especially many in the library of the Trinity College in Dublin.
