Historical Forgeries
The Donation of Constantine (756 CE)
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…
The Holy Foreskin (800 CE)
The Holy Foreskin of Christ first made an appearance in Europe around 800 ce, when King Charlemagne presented it as a gift to Pope Leo III. Being an actual body part of Christ, it was considered to be incredibly valuable. But rival foreskins soon began to pop up all over Europe. Eventually twenty-one different churches claimed to possess the genuine Holy Foreskin. By 1900, the Church had decided that all the rival foreskins were frauds. more…
The Shroud of Turin (1355)
This famous cloth bearing the image of a naked man first came to the attention of the public in 1355. Its supporters claim that it was the funeral shroud of Christ. But skeptics dismiss it as a medieval forgery, arguing that: 1) there was a flourishing trade in such false relics; 2) a medieval forger could definitely have created it, despite claims to the contrary; and 3) the man's body is oddly proportioned (his head is too large), which suggests the image is a painting. more…
The History of Crowland (1413)
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 Hardouin’s Theory of Universal Forgery (1693)
Jean Hardouin was a respected scholar, librarian of the Lycee Louis-le-Grand in Paris, who in 1693 came up with the theory that virtually all classical texts, and most ancient works of art, coins and inscriptions, had been forged by a group of 13th-C monks whose goal was to "establish Atheism amongst men, by paganising all the facts of Christianity." Hardouin claimed he "detected the whole fraud" by spotting a series of clues embedded in classical works, clues such as poor writing and anachronisms. Other scholars initially tried to argue his theory with him, but as he persisted in his views, he came to be seen as a crackpot. His critics referred to his theory dismissively as "Harduinismus." Although Hardouin was definitely an eccentric, his theory nevertheless did indicate the growing awareness amongst 17th-C scholars of the number of errors, exaggerations, and inventions in the historical record. more…
De Situ Brittaniae (1747)
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…

The Kinderhook Plates (1843)
Six bell-shaped pieces of flat copper inscribed with hieroglyphics were unearthed from an Indian burial mound in Illinois. According to some reports, the plates were taken to Mormon leader Joseph Smith, living nearby, who proceeded to translate the markings. After which, the plates were revealed to be the work of local pranksters who intended to embarrass Smith, as the hieroglyphics were meaningless. The Mormon church denies Smith translated the plates. more…
Vrain Lucas (1870)
Lucas produced thousands of letters he said had been written by historical personages such as Aristotle, Julius Caesar, and Alexander the Great. They were all bought by the esteemed mathematician Michel Chasles who didn't suspect they might be fake, even though they were all written in French, on modern paper. It took 18 years for Chasles to realize something was amiss and bring charges against Lucas, who then served two years in jail. more…
