Plate 9 from A familiar treatise on astronomy (1825) depicting Ursa Major, a constellation visible throughout the year in most of the northern hemisphere. In European star charts, the constellation was visualized with the 'square' of the Big Dipper forming the bear's body and the chain of stars as a long tail, even though bears do not have long tails.Image credit: Sidney Hall
