This Index librorum expurgatorum, a reprint of the first Spanish edition of 1584, was published by Protestants at the French university town of Saumur in an effort to expose the methods of the Catholic censors. It includes a preface by the Protestant scholar Philippe de Mornay Du Plessis (1549–1623), who had intercepted a copy of the Spanish Index intended for a Catholic censor.
