Chart of the constellation of Antlia Pneumatica

'Antlia Pneumatica', created by La Caille in 1752, commemorates Robert Boyle's air pump. One of a set of thirty-two cards designed by 'a young Lady' to make the study of astronomy 'familiar and amusing'. It shows the constellations as visible in the night skies of Britain, with easily identifiable classical embodiments. The card is pricked through with holes of different sizes so that the amateur astronomer can hold it up to a light and get an immediate impression of the apparent magnitude of each star. Engraved by Sidney Hall.
