After the works of various authors had been severally prohibited in distinct {420} proclamations, the University of Louvain, at the emperor's command, drew up a fairly extensive list in 1546 and again, somewhat enlarged, in 1550.

It mentions a number of Bibles in Greek, Latin and the vernaculars, the works of Luther, Carlstadt, Osiander, Ochino, Bullinger, Calvin, Oecolampadius, Jonas, Calvin, Melanchthon, Zwingli, Huss and John Pupper of Goch, a Dutch author of the fifteenth century revived by the Protestants.

It is remarkable that the works of Erasmus are not included in this list.

Furthermore it is stated that certain approved works, even when edited or translated by heretics, might be allowed to students.

Among the various scientific works condemned are an _Anatomy_ printed at Marburg by Eucharius Harzhorn, H.C.Agrippa's _De vanitate scientiarum_, and Sebastian Muenster's _Cosmographia universalis_, a geography printed in 1544.
