The City of the Sun is an important early utopian work by Italian philosopher Tommaso Campanella, written after his imprisonment for sedition and heresy. Given as the dialog between "a Grandmaster of the Knights Hospitaller and a Genoese Sea-Captain", The City of the Sun outlines Campanella's vision for a unified world, where property is held in common - Campanella including women and children in this one - and peacefully governed by a theocratic monarchy.
