The Cardiff Giant — carved gypsum buried to mock the literal-minded

On 16 October 1869, on William C. “Stub” Newell’s farm at Cardiff, in the Onondaga Valley of central New York, two hired men digging a well struck a vast stone figure that looked like a petrified human ten feet tall. Word spread within hours, and a tent went up over the pit. It was a fraud from the first stroke. The figure was a block of gypsum, quarried in Iowa and carved in Chicago at the direction of George Hull, a Binghamton tobacconist and avowed skeptic, who had buried it on his cousin Newell’s land roughly eleven months earlier and waited for it to be “found.”

The deception barely outlived its own celebrity. Within weeks geologists pronounced the object impossible, and on 10 December 1869 — under two months after the discovery — Hull confessed the whole scheme to the press, having already pocketed the money. Yale’s pioneering paleontologist Othniel Charles Marsh examined the giant and dismissed it as “of very recent origin, and a most decided humbug,” noting fresh tool marks and a polished surface that water-soluble gypsum could never have kept underground. The courts followed: in February 1870 the giant and a copied rival were both declared fakes.

Hull’s motive was not, at first, money. By his own account he conceived the hoax after a theological argument with a revivalist preacher who insisted, citing Genesis 6:4 — “there were giants in the earth in those days” — that scripture was literally true. Hull set out to manufacture exactly the relic such literalism predicted, then watch the credulous pay to believe it. He spent a reported 2,600 dollars building the giant and recouped a fortune; a syndicate led by the Syracuse banker David Hannum bought a three-quarter interest for a sum reported around 30,000 dollars, and the showman P.T. Barnum, refused the original, simply commissioned a plaster copy and exhibited it as the genuine article.

The Cardiff Giant endures less as a mystery than as a parable. It fooled no expert who was allowed to test it, yet it drew enormous crowds because it confirmed what many wished to be true and arrived wrapped in the authority of the soil. The phrase “there’s a sucker born every minute,” long misattributed to Barnum, is most plausibly traced to Hannum, exasperated that the public was paying to see Barnum’s fake of Hull’s fake. Today the original rests at the Farmers’ Museum in Cooperstown, New York.
