The Venetian and Milan compilers themselves made use of the material collected by the Louvain compilers of 1550, and of the titles in the Casa Index of 1549. They had also taken from the catalogue of Lutzenburg and from the _Bibliotheca_ of Gesner the names of a number of the heretics of the Middle Ages. Further names were secured, curiously enough, from the letters of Oecolampadius and Zwingli, and these last were cited so heedlessly that they include those of a number of persons who were not, in any respect, authors.[117] Reusch points out that in the endeavour, without adequate knowledge, to make their lists comprehensive, the compilers had been led to include a number of unimportant persons some of whom had published nothing religious or theological, while others were, as said, not authors at all. In some instances, large sounding entries cover simply the Latin rendering of the titles of insignificant German tracts (_flügschriften_). The Venetian Index was reprinted (from Vergerio’s reprint) in London, 1840, by Joseph Mendham, in connection with a reprint of the Index of Gregory XXI of 1835. Mendham uses as a general title, _The Literary Policy of the Church of Rome_. The compilers of this Index, like those of Milan, have included the names of a number of persons classed as heretics in the earlier Middle Ages and before the invention of printing, some of whom had never written anything, while of others no writings had been preserved. To this class belong the Wycliffite Richard “Anglicus,” the Hussite, Mathias Boemus, Desiderius Longobardus, Joh. de Poliaco, Petrus de Aragonia, Joh. de Stuma, and Petrus de Luna. These names are taken from Lutzenburg. Of the series of names taken from the Louvain Index of 1550, a number are so altered (either by scribes or by printers) as to be identified with difficulty. From the Index of 1546 are taken Petrus Lignius, and the _Facetiae_ of Poggio and of Bebel. From Gesner are taken thirty writers some of whom are responsible for no books at all either in theology or religion.[118] The list includes Maturin Cordier, the instructor of Calvin, who appears for the first time in the Venetian Index. Other names and titles to be noted are Dante, for the _De Monarchia_ (which was printed for the first time in 1559, in Germany, and first in Italy in 1658), Laurentius Valla, Hubmeyer (whose name was secured from a letter of Zwingli), Botzheim (friend of Erasmus), _Dialogi Obscurorum Virorum_, Eckstein, and Murnarus for his _Leviathan_. The appendix contains a prohibition, taken from Eymeric, of all works on the subjects of geomancy, necromancy, and pyromancy. _13._ _1558._ _Louvain._ In December, 1557, an _ordonnance_ of King Philip II directed the preparation by the theological faculty of Louvain of a revised and enlarged issue of the Index of 1550. This was printed, in Flemish and in French, in 1558. The preface, signed by the Rector of the University, states:
