The case of Richard Simon and the suppression of his book, Histoire critique du Vieux Testament in 1678 stands at a point where the interests of both Church and State in maintaining control of the book trade intersected. As such, the case is of interest in two important areas: first, from the point of view of the social and political history of the ancien régime in France, this case exhibits the intense concern for maintenance or extension of the powers of jurisdiction of the authorities which is so characteristic of the reign of Louis XIV. In some instances this preoccupation with autorité and droit led to an unseemly public jockeying for power, and it is interesting to see how the book trade is seen as a vital element in this struggle.
