Trylogia Ksiezycowa (The Lunar Trilogy or The Moon Trilogy) is a trilogy of science fiction novels by the Polish writer Jerzy Zulawski, written between 1901 and 1911. It has been translated into Russian, Czech, German and Hungarian, and has been reprinted several times in Poland. This A+B edition marks the trilogy's first English translation. The first volume, Na Srebrnym Globie (On the Silver Globe; first book edition: Lwow, 1903) describes, in the form of a diary, the story of a marooned expedition of Earth astronauts who find themselves stranded on the Moon and found a colony. After several generations, they lose most of their knowledge and are ruled by a religious cult.
