This paper analyses Giordano Bruno's dialogue De l’infinito universo e mondi (The Infinite Universe and Worlds), written during his stay in England (1583–85), in the context of his philosophical works and, particularly, within the context of scientific and imaginative writings such as Cyrano de Bergerac's Other Worlds (published posthumously in 1662) and Francis Godwin's The Man in the Moone (1638). The article also discusses the contemporary speculations of Galileo and Kepler regarding the existence of a plurality of worlds and the (...) presence of creatures on the moon and their rapport with humans. Besides the imaginative, fantastic and pseudoscientific elements, attention is also given to religious implications and attitudes, especially in the case of Godwin, who, like his countryman John Wilkins—author of The Discovery of the Worlde in the Moone (1638)–was a bishop and therefore wanted to avoid any controversy with the church.
