Following the title, comes an address to the reader from the Rector and Faculty of the University. The Louvain catalogue comprises 295 titles, of which 62 are of works in Flemish and in Dutch, and 233 of works in Latin. The Archbishop’s catalogue comprises 69 titles, of which 55 are of works in Latin and 14 of works in Spanish. In the Louvain list are included certain specific writings of Erasmus, and also his entire works (“Opera Omnia”). Erasmus was himself the most distinguished student whom Louvain had sent out. There are also editions of the Bible as printed in Paris by Robert Estienne, the works of Luther, Zwingli, Melanchthon and other Reformers, etc. The Latin books are from presses in Paris, Antwerp, Basel, Cologne, The Hague, etc. The Flemish and Dutch titles are from Antwerp, Ghent, Middelburg, and Leyden. The Archbishop’s Latin list includes the Koran and “all books containing the errors of Mahomet,” the writings of Servetus, Œcolampadius, and Zwingli, and the “Colloquies” of Erasmus. His Spanish list includes “all books printed in Hebrew,” and “all theological works printed in Arabic”; also “all editions of the Bible printed in the vulgar tongue.” III. THE SAME LOUVAIN INDEX OF 1550. Printed in Cordova, by Francisco Ferdinand in 1551. This volume includes, in addition to the titles of the books condemned by the Divines of Louvain, a list of thirty works sanctioned by the University for use as text-books. Among these are a Syntax, a Greek Grammar, a “Copia,” and a Guide to letter-writing, by Erasmus of Rotterdam, volumes which under a strict construction of language might naturally be understood to be included among the “Opera Omnia” of Erasmus, condemned in the previous list. Following the list of the text-books authorised, is the catalogue of the books previously condemned by the Inquisition, comprising eighty-five titles. This includes various writings of Erasmus, Luther, Servetus, Melanchthon, Zwingli, and other Reformers, also all versions of the Bible in Spanish or in other vulgar tongues. IV. THE CORDOVA INDEX OF 1554. This is described on its title-page as a “Censura Generalis contra errores, quibus recentes haeretici Sacram Scriptorem asperserunt, edita a supremo senatu Inquisitionis adversus hereticam provitatem et apostasiam in Hispania, et aliis regnis, et dominiis Cæsareæ Majestatis constituto.” It was printed at Cordova by Francisco Ferdinand, and was sold for forty maravedas.
