Tommaso Campanella (1568-1639) was an Italian philosopher, theologian, astrologer, and poet, notable for his utopian vision and critique of Aristotelianism. A Dominican friar, his most famous work, "The City of the Sun," describes an ideal society where goods, knowledge, and work are shared, reflecting his radical political and philosophical ideas. Campanella spent 27 years in prison for his heretical views and involvement in a conspiracy against Spanish rule in Calabria. Despite his incarceration, he produced significant works on philosophy, theology, and science, advocating for the reconciliation of science and religion. Campanella's thought influenced later Enlightenment thinkers and utopian literature.
