In the 16th century, immediately following the publication of the Prince, Machiavellianism was seen as a foreign plague infecting northern European politics, originating in Italy, and having first infected France. It was in this context that the St. Bartholomew's Day massacre of 1572 in Paris came to be seen as a product of Machiavellianism, a view greatly influenced by the Huguenot Innocent Gentillet, who published his Discours contre Machievel in 1576, which was printed in ten editions in three languages over the next four years.<2> ...In fact there is little trace of Machiavelli in French writings before the massacre, not that politicians telegraph their intentions in writing, until Gentillet's own book, but this concept was seized upon by many contemporaries, and played a crucial part in setting the long-lasting popular concept of Machiavellianism.<4>
The English playwright Christopher Marlowe was an enthusiastic proponent of this view. In The Jew of Malta (1589–90) "Machievel" in person speaks the Prologue, claiming not to be dead, but to have possessed the soul of (the Duke of) Guise, "And, now the Guise is dead, is come from France/ To view this land, and frolic with his friends" (Prologue, lines 3–4)<5> His last play, The Massacre at Paris (1593) takes the massacre, and the following years, as its subject, with the Duke of Guise and Catherine de' Medici both depicted as Machiavellian plotters, bent on evil from the start.
