Among Renaissance utopias, The City of the Sun is perhaps second in importance only to More's more famous work. There are striking similarities between Campanella's utopia and More's, but also striking differences which reflect both changed historical circumstances and the highly original nature of Campanella's thought. La città del sole is one of many books written by Tommaso Campanella―philosopher, scientist, astrologer, and poet―while imprisoned in Naples for his part in rebellion against the Spanish and ecclesiastical authorities who ruled his native Calabria. This first faithful and complete English translation by Daniel J. Donno is presented opposite the critically established Itaion text, with essential explanatory notes and an introductory essay. Students of Italian culture, of the history of science, and of political, philosophical, and religious thought will welcome the publication of this authoritative edition of Campanella's best-known work.
