The Stamp Act was to take effect from the first of August. Censorship of the press began in the Church soon after the invention of printing. The ecclesiastical superintendence introduced in 1479 and 1496 was more completely established by a bull of Leo X. in 1515, which required Bishops and Inquisitors to examine all books before printing, and suppress heretical opinions. The Church of Rome still adheres to the
Index Librorum Prohibitorum
begun by the Council of Trent in 1546; and there is an Index Expurgatorius for works partly prohibited, or to be read after expurgation. In accordance with this principle, the licensing of English books had been in the power of the Archbishop of Canterbury and his delegates before the decree of the Star Chamber in 1637, which ordered that all books of Divinity, Physic, Philosophy, and Poetry should be licensed either by the Archbishop of Canterbury or by the Bishop of London personally or through their appointed substitutes. The object of this decree was to limit the reprint of old books of divinity, &c. Thus Foxe's
Book of Martyrs
