French astronomer Camille Flammarion (1842–1925) firmly believed that science should not be the preserve of elites. His passion for the discoveries of his time is palpable throughout this classic introduction to astronomy, which stands as a landmark in the history of popular science writing. It features 360 illustrations, including highly detailed maps of the Moon and Mars, the latter being of special interest for Flammarion as he compared and contrasted it with the Earth. Originally published in 1880, the work won the approval of the Académie Française and the Minister of Public Instruction. This reissue is of the version that appeared in 1881 after 50,000 copies had already reached an enthusiastic readership. Its translation into English as Popular Astronomy (1894) and another accessible work by Flammarion, Le Monde avant la création de l'homme (1886), are also reissued in this series.
