 The religious beliefs of the citizenry, even though they include fundamental principles of Christianity such as the immortality of the soul and divine providence, form a natural religion that establishes a sort of osmosis between the city and the stars. The temple is open and not surrounded by walls. In one of his poems Campanella promises: “I shall make the heavens a temple and the stars an altar” (Poesie, 1998, p. 327). On the vault of the temple’s dome the stars are depicted together with their influence on earthly affairs. The altar, on which are placed a celestial and a terrestrial globe, is in the form of the sun. Prayers are directed toward the heavens. The task of the twenty-four priests, who live in cells located in the highest part of the temple, is to observe the stars and, using astronomical instruments, to take account of all their movements. It is their job to indicate the times most favorable for generation and for agricultural labors, acting in this way as intermediaries between God and human beings.
