Selenographia, sive Lunae descriptio (Selenography, or A Description of The Moon) is a milestone work by Johannes Hevelius, printed in 1647. In his treatise Hevelius reflected on the difference between his own work and that of Galileo Galilei. Hevelius remarked that the quality of Galileo's representations of the Moon in Sidereus nuncius (1610) left something to be desired. Selenography... was dedicated to king Wladyslaw IV and along with Riccioli/Grimaldi's Almagestum Novum became the standard work on the Moon for over a century.1 There are two copies survived, they are kept in Bibliothèque nationale de France and in the library of Polish Academy of Sciences.2
