Serendipity: The Word Invented in a Letter
The Letter
On 28 January 1754, the English writer and politician Horace Walpole wrote a letter to his friend Horace Mann, the British envoy in Florence. Describing a minor discovery he had made about a lost painting, Walpole coined a new word:
> *"This discovery, indeed, is almost of that kind which I call Serendipity, a very expressive word… I once read a silly fairy tale, called The Three Princes of Serendip: as their Highnesses travelled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of."*
Walpole's definition contains a crucial nuance often lost today: serendipity is not mere luck. It requires sagacity — the wisdom to recognize the significance of an unexpected finding. The princes didn't just stumble onto things; they were clever enough to understand what they had found.
The Fairy Tale
The tale Walpole referenced, *The Three Princes of Serendip*, was published in Italian by Michele Tramezzino in Venice in 1557, translated from a lost Persian original. Serendip (also spelled Serendib, Sarandīb) is the old Arabic and Persian name for Sri Lanka, derived through Pali from Sanskrit Siṃhaladvīpa — literally 'lion-island' (*siṃha* = lion, *dvīpa* = island).
The same Sanskrit root *siṃha* gives us Singapore (Siṃhapura, 'lion city') and the Sinhalese people themselves. So hidden inside *serendipity* is the ancient Sanskrit word for lion.
150 Years of Obscurity
Walpole's coinage appeared only in his private correspondence, published posthumously. The word was used sporadically through the 19th century — the *Oxford English Dictionary* records scattered citations — but it remained a curiosity. It was the early 20th century that brought serendipity into common use, particularly after the sociologist Robert K. Merton championed the concept in his work on scientific discovery.
The Untranslatable Favourite
In 2004, a British Council survey of 40,000 people in 102 countries named *serendipity* the most popular English word — and translators consistently rank it among the hardest to render in other languages. Most languages have simply borrowed it wholesale: French *sérendipité*, German *Serendipität*, Japanese *セレンディピティ*.
The antonym zemblanity (making unhappy, unsurprising discoveries) was coined by novelist William Boyd in 2004, from Nova Zembla, a cold, barren Arctic archipelago — the anti-Serendip.
Serendipity in Science
Some of history's greatest discoveries are attributed to serendipity: penicillin (Fleming's contaminated petri dish), X-rays (Röntgen's fluorescent screen), the microwave oven (Percy Spencer's melted chocolate bar), and Viagra (originally a heart medication). In each case, the discoverer needed Walpole's 'sagacity' to see what the accident meant.
