about Thule, but de Bury, who promised to reply when he was back at home among his books, never responded to repeated enquiries. Pope John XXII made him his principal chaplain, and presented him with a rochet in earnest of the next vacant bishopric in England. Bishop of Durham During his absence from England de Bury was made Dean of Wells in February 1333. In September of the same year, he was made Bishop of Durham by the king, over-ruling the choice of the monks, who had elected and actually installed their sub-prior, Robert de Graystanes. In February 1334 de Bury was made Lord Treasurer, an appointment he exchanged later in the year for that of Lord Chancellor.

In June 1338 he was once again sent abroad on a peace mission, but within a month was waylaid by the approaching campaign.

In 1340 and 1342 he again tried to negotiate peace with the Scots, but afterwards left public politics to care for his diocese and accumulate a library. He sent far and wide in search of manuscripts, rescuing many volumes from the charge of ignorant and neglectful monks. He may sometimes have brought undue pressure to bear on the owners, for it is recorded that an abbot of St Albans bribed him with four valuable books, and that de Bury, who procured certain coveted privileges for the monastery, bought from him thirty-two other books for fifty pieces of silver, far less than their normal price. The record of his passion for books, his Philobiblon (Greek for "The Love of Books"), is a Latin treatise in praise of books. The Philobiblon was completed in 1344 and first printed in 1473. The most accurate and reliable English translation is by Ernest C. Thomas in 1888. Alfred Hessel describes the Philobiblon as "[t]he particular charm of the
