История голландской тюльпаномании оказалась вымыслом, основанным на пропаганде и плагиате

Much of what people think they know about Dutch tulip mania comes from one book, written in 1841, and that book inherited much of its story from satirical songs and pamphlets written to mock greedy speculators. Anne Goldgar traced the familiar stories back through the centuries and found that “they are based on one or two contemporary pieces of propaganda and a prodigious amount of plagiarism.” Much of the traditional picture of tulip mania, she writes, was based “almost solely on propaganda, cited as if it were fact.” Her point is blunt: generations of writers inherited the story through Mackay’s unreliable retelling and the Dutch archives back her up. The book that built the myth The story most people can half-recite goes like this. In the 1630s the Dutch, from chimney-sweeps to aristocrats, poured their savings into tulip bulbs. A single rare bulb could cost as much as a good house. Then, in the winter of 1637, the market collapsed overnight, and ruined speculators threw themselves into the canals. That version reached us mainly through one book. Charles Mackay published Memoirs of Extraordinary Popular Delusions in 1841, and its tulip chapter became the standard account. It turns up in finance books and gets quoted every time a new bubble inflates. The problem is where Mackay got his material. Satirical pamphlets dressed as history Mackay was not working from court records or account books. He leaned on an earlier German scholar, Johann Beckmann, who in turn drew on 17th-century Dutch writing that was never meant as reporting. Goldgar traces much of what Mackay wrote back to satirical songs from 1637, verses written to poke fun at speculators and preach about greed, not to record who actually bought what. Read a satire as if it were a police report and you inherit all its exaggerations. It seems that is roughly what happened across two centuries of retelling. What the archives actually show Goldgar spent years in Dutch archives, reading legal documents, court files, and wills from several towns. What she found looks nothing like the legend. She put it plainly: “There weren’t that many people involved and the economic repercussions were pretty minor. I couldn’t find anybody that went bankrupt.” The numbers are small. Goldgar could find only 37 buyers who spent more than 300 guilders on bulbs, roughly what a skilled craftsman earned in a year. The most expensive tulips did reach around 5,000 guilders, the price of a “well-appointed” house, but most sold for far less. Bulbs did not change hands hundreds of times either. The longest chain of buyers she could trace was five. Even the crash was quieter than the story says. When prices fell in February 1637, most of the losses were only on paper. The bulbs were still in the ground and no money would be exchanged until they could be delivered. As for the drowned speculators, Goldgar was direct in a later account: “No one drowned themselves in canals. I found not a single bankrupt in these years who could be identified as someone dealt the fatal financial blow by tulip mania.” The stories of widespread ruin and the sailor jailed for eating a bulb are unsupported too. Goldgar is not the only one to land softer than the myth. The economist Peter Garber studied the price data and argued the episode was less irrational than it looks, because much of the money went into genuinely rare, unusual bulbs. He was careful, though. As Garber put it, “While the lack of data precludes a solid conclusion, the results of the study indicate that the bulb speculation was not obvious madness.” Why the myth stuck A cautionary tale about greed is simply more useful than a story about a small luxury market cooling off. The tulip legend fits any moment of financial excess, a tidy warning with a satisfying moral. That it started as satire is arguably what made it last: satire is built to be memorable, and to let the reader feel superior to the fools in the story. Goldgar’s own take on the correction is refreshingly unglamorous. She likes to joke that her book should be called “Tulipmania: More Boring Than You Thought.” What the records describe is a small, contained affair: a limited trade in a fashionable flower, among a few hundred merchants and skilled artisans, many of them closely connected, that rose and fell without dragging the Dutch economy down. The legend has outlived the evidence for nearly two centuries. The evidence, patient and dull, has been in the archives the whole time.
