History Hoaxes
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 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…
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…
Appleton’s Cyclopedia of American Biography (1887)
This six-volume biographical encyclopedia, published between 1887 and 1889, was one of the first and most definitive works of its kind in America, containing information about thousands of people (some famous, some obscure) in American history. But thirty years after its publication, researchers discovered that a number of the people described in the work were fictitious. Over the years, more and more false entries have been found — to date over 200 of them. But due to the enormity of the work it's doubtful that all of the false information it contains will ever be identified. more…
Mencken’s History of the Bathtub (1917)
On December 28, 1917, H.L. Mencken published an article in the New York Evening Mail titled "A Neglected Anniversary." It described the history of the bathtub in America, noting that people were slow to accept tubs, believing they were dangerous to health. This attitude, Mencken said, changed when President Millard Fillmore became the first president to install a tub in the White House. Mencken's history of the bathtub was not true. He intended it as a joke, "some harmless fun in war days". However, few people recognized it as such. Details from Mencken's article began to appear in other papers. One scholar included the tale in a history of... more…
