One of the most important early works dedicated to criticism of Machiavelli, especially "The Prince", was that of the Huguenot, Innocent Gentillet, "Discourse against Machiavelli", commonly also referred to as "Anti Machiavel", published in Geneva in 1576. He accused Machiavelli of being an atheist and accused politicians of his time by saying that they treated his works as the "Koran of the courtiers". Another theme of Gentillet was more in the spirit of Machiavelli himself: he questioned the effectiveness of immoral strategies (just as Machiavelli had himself done, despite also explaining how they could sometimes work). This became the theme of much future political discourse in Europe during the 17th century. This includes the Catholic Counter Reformation writers summarised by Bireley: Giovanni Botero, Justus Lipsius, Carlo Scribani, Adam Contzen, Pedro de Ribadeneira, and Diego de Saavedra Fajardo. These authors criticized Machiavelli, but also followed him in many ways. They accepted the need for a prince to be concerned with reputation, and even a need for cunning and deceit, but compared to Machiavelli, and like later modernist writers, they emphasized economic progress much more than the riskier ventures of war. These authors tended to cite Tacitus as their source for realist political advice, rather than Machiavelli, and this pretense came to be known as "Tacitism".
