of Fulda and Meginfrid's nonexistent treatise De temporibus gratiae to substantiate Trithemius's ideal of monastic piety and erudition, which were supposed to be the same values shared by the monks of the ninth century. Others opine that Meginfrid was not strictly forgery but the combination of wishful thinking with faulty memory. In the process though, Trithemius became a famous builder of libraries, which he created in Sponheim and Würzburg. In Sponheim, he set out to transform the abbey from a neglected and undisciplined place into a centre of learning. In his time, the abbey library increased from around fifty items to more than two thousand. His efforts did not meet with praise, and his reputation as a magician did not further his acceptance. Increasing differences with the convent led to his resignation in 1506, when he decided to take up the offer of the Bishop of Würzburg, Lorenz von Bibra (bishop from 1495 to 1519), to become the abbot of St. James's Abbey, the Schottenkloster in Würzburg. He remained there until the end of his life. Trithemius seemed to have a falling out with Maximilian regarding their differences when the emperor wanted to organize a separate ecclesiastical council in 1511, in slight of Pope Julius II. The relationship recovered after Julius's death, though. Death Trithemius was buried in St. James's Abbey's church; a tombstone by the famous Tilman Riemenschneider was erected in his honor. In 1825, the tombstone was moved to the Neumünster church, next to the cathedral. It was damaged in the firebombing of 1945, and subsequently restored by the workshop of Theodor Spiegel. Legacy Notably, the German polymath, physician, legal scholar, soldier, theologian, and occult writer Heinrich Cornelius Agrippa (1486–1535) and the Swiss physician, alchemist, and astrologer Paracelsus (1493–1541) were among his pupils. Steganographia Trithemius' most famous work, Steganographia (written c. 1499; published Frankfurt, 1606), was placed on the Index Librorum Prohibitorum in 1609 and removed in 1900. This book is in three volumes, and appears to be about magic—specifically, about using spirits to communicate over long distances. Since the publication of the decryption key to the first two volumes in 1606, they have been known to be actually concerned with cryptography and steganography. Until recently, the third volume was widely still believed to be solely about magic, but the "magical" formulae have now been shown to be covertexts for yet more cryptographic content. However, mentions of the
