Known as "America's Greatest Hoax," this 10-foot (3-meter) tall stone statue of a "petrified" ancient giant made its 19th-century creator, George Hull, a very rich man.
Hull was a get-rich-quick schemer and a proud atheist in a time of great religious fervor. After an argument with a revivalist preacher over the existence of giants as mentioned in the book of Genesis, Hull conceived a devious plan that would capitalize on the gullibility of the public [source: Roadside America].
In 1868, Hull hired a Chicago stonecutter to carve a massive hunk of gypsum in Hull's own likeness [source: The Farmers' Museum]. Hull then "aged" the stone with a sulfuric acid and convinced a farmer in Cardiff, New York, to secretly bury it in his backyard. A year later, Hull had the farmer dig a well, instructing the workmen to dig exactly where the stone giant was buried.
The unearthing of the Cardiff Giant caused a great sensation in upstate New York, still a hotbed of spiritual excitement. (Remember the Fox Sisters?) News of the creature spread far and wide, inciting fierce debate over the artifact's authenticity. Hull fanned the fires of speculation, taking the giant on tour and charging 50 cents for a peek. Rumor has it he made $30,000, a fortune in the 1860s [source: Roadside America].
You can still see the Cardiff Giant at The Farmer's Museum in Cooperstown, New York.
