El maquiavelismo degollado sounds as a challenge to all statesmen who could be tempted to follow the pragmatic way shown by Machiavelli rather than by the Roman Catholic Church. Then, Claude Clément was considered as a champion of the radical line in the anti-Machiavellian school of thought; however, the book has never been republished and, therefor, is not very well known. El maquiavelismo degollado is not a unique work knowing that three different books have been published, using two different languages and that the Spanish version really seems to be a re-written text rather than a simple translation. Scattered with reproductions of foreign documents, enriched with many allusions, quotations, some of them hidden away, this work seems to be a miscellany of political theories of its time. Using digital databases, this study attempts first to establish the text of El maquiavelismo degollado respecting its complexity, then to explain the main mechanism of its evolution from one version to the other and finally to determine how other works could have influenced it.
