As an important early utopian work by Tommaso Campanella, The City of the Sun describes a theocratic society where goods, women and children are held in common.

The book is presented as a dialogue between "a Grandmaster of the Knights Hospitaller and a Genoese Sea-Captain".

Tommaso Campanella (1568 – 1639), was a Dominican friar, Italian philosopher, theologian, astrologer, and poet.
