 Over the course of the almost thirty years that intervened between the composition of Atheismus triumphatus and the publication of the definitive Paris edition of 1636, the treatise had to overcome many obstacles, following a tortuous itinerary, due to the suspicions of the ecclesiastical authorities, who accused the work of Pelagianism and thus of excessively exalting the natural capacities of humans and diminishing divine grace by restricting it to far too narrow confines. The work was not published despite the initiative of Schoppe; nor was it among those that appeared in Frankfurt between 1617 and 1623 due to the efforts of Tobias Adami. With the failure of these attempts, Campanella thought of publishing it in Italy; but the treatise still had to face numerous difficulties and to be censored more than once before it came out in the Rome edition of 1631, which was soon afterwards impounded. After repeated entreaties to put the book back into circulation, Campanella took the decision to reprint it in Paris; and Atheismus triumphatus was published, along with other writings, at the beginning of 1636 in a volume dedicated to Louis XIII.
