And that the primitive Councils and bishops were wont only to declare what books were not commendable, passing no further, but leaving it to each one's conscience to read or to lay by, till after the year 800, is observed already by Padre Paolo, the great unmasker of the Trentine Council.

After which time the Popes of Rome, engrossing what they pleased of political rule into their own hands, extended their dominion over men's eyes, as they had before over their judgments, burning and prohibiting to be read what they fancied not; yet sparing in their censures, and the books not many which they so dealt with: till Martin V., by his bull, not only prohibited, but was the first that excommunicated the reading of heretical books; for about that time Wickliffe and Huss, growing terrible, were they who first drove the Papal Court to a stricter policy of prohibiting. Which course Leo X. and his successors followed, until the Council of Trent and the Spanish Inquisition engendering together brought forth, or perfected, those Catalogues and expurging Indexes, that rake through the entrails of many an old good author, with a violation worse than any could be offered to his tomb.
