Literary Forgery

The Donation of Constantine was a document supposedly written by the Emperor Constantine, granting the Catholic Church ownership of vast lands in the western Roman Empire. For centuries, it was accepted as authentic, until 1440, when the scholar Lorenzo Valla used textual analysis to expose it as a fraud. Valla's analysis represented the growing influence of Renaissance Humanism, and a new willingness in Europe to question long-held beliefs. More…
At a time when European rulers felt threatened by the growing power of Muslim nations on their borders, a letter suddenly appeared from Prester John, who described himself as a Christian king of vast wealth and power living in the far east. Hopes were raised that Prester John would come to the aid of Europe's Christian nations, and expeditions were sent to search for him. But Prester John was never found. The letter's true author remains unknown. More…
During the early 15th Century, when a neighboring abbey claimed a portion of the land of Crowland Abbey (located in the Lincolnshire Fens of England) as its own, the Crowland monks presented legal authorities with a volume known as the Historia Crowlandensis, or History of Crowland, to document their historical ownership of the disputed lands. The History was accepted as legitimate, and the Crowland monks won their case. It wasn't until the 19th Century that historians realized the History was, for the most part, an invention. It contained numerous anachronisms, such as referring to monks who had supposedly studied at Oxford, long before the University was founded. It also claimed that many of the monks had lived to ages well past 100. Such longevity would be hard-to-believe today, let alone in the Middle Ages. More…
Jean V d'Armagnac was the penultimate Count of the French province of Armagnac. He became infamous after he fell in love with his younger sister and had two sons with her. He sought approval from the Pope to marry her, but the Pope refused. Undeterred, the Count bribed a papal official to forge a papal bull allowing the marriage. When the Pope learned of this, he excommunicated the Count. Later, King Charles VII's army killed the Count and dragged his body through the streets. More…
Carlo Sigonio was a highly respected Italian scholar who specialized in the history of Rome. Around 1583, he claimed that he had discovered a new complete work by the great Roman orator Cicero, titled De Consolatione or the Consolation. In it Cicero grieved for his daughter's death. Only small fragments of this work had ever been found before. The discovery of this manuscript caused great excitement, but when other scholars read it, the general consensus was that it had to be a fake as it contained numerous anachronistic phrases and Italian mannerisms that Cicero would never have used. Sigonio stubbornly defended the work, but today it is still regarded as being a forgery. Sigonio probably wrote the book himself, perhaps to display his mastery of Ciceronian scholarship.
A young teacher in Denmark claimed to have found an ancient map, titled De Situ Brittaniae, that detailed the layout of roads and settlements in Roman Britain. The discovery caused enormous excitement amongst antiquarians because it revealed numerous Roman landmarks, as well as an entire province, whose existence hadn't been previously known. But the map turned out to be a forgery. More…
Bookseller Samuel Ireland was a passionate fan of Shakespeare, so he was overjoyed when his son, William Henry, claimed to have found a previously unknown play written by the Bard. Arrangements were made for the play to be performed. But the actors, suspecting a fraud, made a mockery of it. Soon after, William confessed the play was indeed his own work. However, his heartbroken father refused to believe the confession. More…

Leonainie (1877)

Under the heading "Posthumous Poetry," Indiana's Kokomo Dispatch published a poem titled "Leonainie" on August 3, 1877. It was an unremarkable poem except in one way. The editor of the Dispatch, John Henderson, claimed it was a previously unpublished poem by Edgar Allan Poe. (Click here to read the poem.)

The publication of this poem generated excitement among fans and scholars of Poe, and within a few weeks it had been reprinted in major papers throughout the United States. But in reality it was not a poem by Poe. Its true author was a struggling young Indiana poet, James Whitcomb Riley. More…
The announcement by the German news magazine Stern that it had discovered the personal diaries of Adolf Hitler generated a media frenzy. Magazines bid for the right to serialize them. Historians anticipated what revelations they would contain. Skeptics, however, insisted they had to be a fake, since Hitler had never been known to keep a diary. The skeptics turned out to be right. Less than two weeks after the initial announcement, forensics experts denounced the diaries as a "crude forgery." When all the dust settled, the diaries turned out to be one of the most expensive fakes in history. By some accounts, the debacle cost Stern as much as 19 million marks. More…
