The authorship of the Vindidae has been a vexed question for 350 years, and perhaps it is not likely to be solved. The book belongs, in the main, to a body of Huguenot literature which appeared after 1572 and was concerned with the dangerous question of the right of resistance. A good deal of this literature was sedulously and obstinately anonymous. There was a reason. If a writer advocated resistance, and, still more, if he advocated or even condoned “tyrannicide,” he would be committing himself to something as abhorrent to the general opinion of his age as “Bolshevism”is to the general opinion of ours. If in addition he backed his opinions by his name, and his name were that of a known adherent of the Calvinist cause, he would be committing that cause to certain obloquy and possible danger. He would be trespassing beyond the bounds of cautious and guarded discretion which Calvin had imposed upon himself in this matter: he would be giving to the enemies of Calvinism the very handle which they desired. In these conditions anonymity flourished: pseudonyms were rife; and calculated puzzles were set to baffle future ages. Not only are we confronted by problems of authorship: we have also to face other and lesser problems. Sometimes, for example, the place and the date of publication are falsified. There was indeed a particular reason for such falsification. Printers as well as authors—perhaps even more than authors—had to be wary; and a genuine place and date of publication afforded too easy a clue.
