A chart of the constellation Bootes

Boötes the hunter and his dogs are said to have the job of keeping the other constellations in place. 'Coma Berenices', 'Berenice's Hair', is the hair of Queen Berenice of Egypt, which became a constellation around 230 BC. 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.
