 After having submitted to an inquest in Naples over his advocacy of Telesian philosophy in 1592, Campanella went first to Rome, then to Florence and Padua, where, at the beginning of 1594, he was denounced and arrested for heresy. In October he was transferred to a prison of the Roman Inquisition, in which the “heretical” Florentine Francesco Pucci and the philosopher Giordano Bruno were imprisoned. In a sonnet entitled “Al carcere” (“To Jail”), Campanella could not but reflect on the fact that free spirits who, abandoning the stagnant waters of a traditional culture in order to hurl themselves boldly into the “sea of truth”, found themselves enclosed, as if by a tragic and fatal destiny, in the dismal palace of the Inquisition, that he compares to the cave of Polyphemus, the labyrinth of Crete and the palace of Atlas (Poesie, 1998, p. 254). Accused of supporting atomist and atheist doctrines, he was condemned in 1595 “on grave suspicion of heresy” and forced to make a formal public abjuration. At the end of 1597 the superiors of the Dominican Order commanded him to return to Calabria.
