An occasional slip of the keyboard or pen can lead to errors in spelling, punctuation, or grammar, and while they may seem trivial or even funny when they happen, some typos have had significant consequences. One infamous example of a typographical error is a 17th-century printing of the Bible that caused an uproar after it changed the meaning of one of the Ten Commandments. NASA’s onetime coding error, meanwhile, has been called the most expensive typo in history.

In the grand scheme of things, typos may appear as minor nuisances, but these minuscule mistakes can spark conversations and even shape historical narratives. Read on to learn about some famous typos that remind us that even the smallest errors can have profound consequences.

The “Wicked Bible”

In 1631, a small but significant typo shook the religious world. In a reprint of the King James Bible by royal printers Robert Barker and Martin Lucas, the word “not” was egregiously left out of the Seventh Commandment, “Thou shalt not commit adultery,” which was mistakenly printed as “Thou shalt commit adultery.” The typo appeared in about 1,000 copies of the text, which later came to be known as the “Wicked Bible” or “Sinners’ Bible.” It isn’t clear how the misprint happened. Some theories over the years have suggested that a rival printer might have done it deliberately, but the more likely cause was simple oversight. When the error was discovered, the ramifications were swift and severe. The king fined the printers £300 (around $70,000 today), revoked their printing license, and proceeded to find and destroy as many copies of the Wicked Bible as possible, turning it into a rare collector’s item. Today, only about 20 copies remain in circulation.

NASA’s Million-Dollar Typo

On July 22, 1962, NASA’s Mariner 1 spacecraft, designed for a mission to Venus, was set to launch from Cape Canaveral. But just minutes after liftoff, the shuttle had to be destroyed due to a course deviation. The culprit behind this mission-ending error was a simple coding mistake. While it’s been widely reported that a missing hyphen in the software coding was to blame, NASA has said that it was an “omission of an overbar for the symbol R for radius (R instead of R̅) in an equation,” as well as a guidance antenna on the atlas, that caused the failure. Mariner 1 was set to be America’s first interplanetary probe. It set NASA back $18.5 million (over $180 million today), an amount that led 2001: A Space Odyssey author Arthur C. Clarke to call it “the most expensive hyphen in history.” Just 36 days later, Mariner 2 successfully launched and flew by Venus, becoming humankind’s first successful scientific planetary mission.

For many of us, fairy tales provide an introduction to the world of storytelling, with anecdotes of enchanted realms, scary monsters, and dashing princes delivering early lessons on worldly matters of good and evil.

But despite the simplicity of these stories, and the happily-ever-after versions that became widely known, the origins of fairy tales are often far more complex. Many evolved over hundreds or even thousands of years, while some, in earlier iterations, would be downright shocking to the delicate sensibilities of a preschool audience.

Here are six such fairy tales that originated well before Walt Disney first dreamed of singing dwarves, taking shape over many moons before winding their way into a children’s book near you.

Rumpelstiltskin

According to one study, the elements of some famous fairy tales date back as far as 4,000 years ago, around the time early forms of the Germanic and Celtic language families were emerging. One of those tales is “Rumpelstiltskin,” with its narrative of a mysterious imp who spins straw into gold. 

This particular story first appeared in print by way of 16th-century German satirist Johann Fischart, who described a game of “Rumpele stilt oder der Poppart” in which children pretend to be a noisy goblin. Like many fairy tales, “Rumpelstiltskin” became more widely known after being included in a collection of oral stories by German scholars Jacob and Wilhelm Grimm, better known as the Brothers Grimm, who published multiple editions of their famed Children’s and Household Tales beginning in 1812.

For as long as the written word has been set down on the printed page, typos have existed. One notorious typographical error was found within the so-called Wicked Bible, a 1631 edition of the King James Bible in which pious readers were advised, “Thou shalt commit adultery.” Further examples abound, from Shakespeare’s typo-ridden folios to first editions of Harry Potter and the Philosopher’s Stone in which “one wand” is erroneously included twice in Harry’s school supply list. In the latter case, lucky owners of these highly collectible first editions, of which only 500 were printed, found themselves in possession of a book — typo included — that fetched $90,000 in an auction. But typos don’t always add value — in fact, they can end up being very expensive. From a stray comma that ended up costing millions to a tiny typo that crashed a spacecraft, here are seven small mistakes that carried enormous price tags.

A Not-So-Fruitful Comma 

A U.S. tariff act originally drafted in 1870 allowed “fruit plants, tropical and semi-tropical for the purpose of propagation or cultivation” to be exempt from import tariffs. As written here, “fruit plants” referred specifically to the plants that fruits grow on, and not the fruits they produce. Then, in 1872, an updated tariff act was released, with an unfortunate comma that changed everything. The errant comma somehow snuck in between “fruit” and “plants,” and suddenly tropical and semi-tropical fruits — most of which were expensive — could be imported without any charge. This reportedly cost nearly $2 million in lost tariff revenue, the equivalent of $53 million in today’s money.

Why Don’t We Write in Cursive Anymore?

For generations, American children learned to loop their letters into graceful, flowing words. Notes passed in class, signatures practiced on notebooks, the elegance of a handwritten letter — all of it once depended on cursive. Yet for much of the last two decades, cursive seemed destined to fade into history.

The decline was especially sharp after 2010, when cursive was omitted from the Common Core education standards. Typing skills were prioritized instead, and many schools quietly dropped cursive instruction altogether. An entire cohort of students grew up with little or no exposure to this form of penmanship. In 2022, former Harvard President Drew Gilpin Faust recalled that in one of her history seminars, two-thirds of the students admitted they couldn’t read or write cursive. So how did cursive, once a cornerstone of education, fall out of favor? And is there any chance it will return?

Why Cursive Faded

For much of the 19th and 20th centuries, and even earlier, penmanship was regarded as a marker of both education and refinement. Historically, handwriting instruction — including cursive — was considered a cornerstone of elementary education. It was seen not only as a practical skill but as a way to instill discipline, patience, and even character in young students. 

The reasons for cursive’s decline are layered. Some educators argue that while handwriting in general aids child development, cursive is no more beneficial than writing in print. The digital shift also played a role: By the mid-2000s, schools were investing heavily in computer labs and keyboarding classes. 

When Common Core omitted cursive for K-12 education, many districts saw little reason to keep it. (Although school curriculums are set at the state and not federal level in the U.S., 41 states agreed on the Common Core standards.) Teachers prioritized developing digital skills and “teaching to the test” — meeting the demands of standardized testing.

We Tried Writing With a Quill, and Here’s What We Learned

The use of quill pens dates back to the sixth century CE, when the feathers of large birds — primarily geese, turkeys, swans, and even crows — replaced the reed pens that had been used previously. Though it’s an obsolete writing utensil today, the quill pen remains a symbol of education, literature, and artistic expression. Many important historical documents were written using quill and ink, from the Magna Carta to the Declaration of Independence, and white quills are still laid out every day the U.S. Supreme Court is in session. 

In pop culture, the Harry Potter series has helped generate interest in the old-fashioned writing instrument, and Taylor Swift, noting the influences of Charlotte Brontë and period films, has referred to some of her music as “Quill Pen Songs.” “If my lyrics sound like a letter written by Emily Dickinson’s great-grandmother while sewing a lace curtain, that’s me writing in the quill genre,” she explained at the Nashville Songwriter Awards in 2022.

So what is it actually like to write with the quill pens of yore? To answer that question, I turned to the internet for authentic supplies and expert advice, and set out scribbling. Here’s what I learned from the experience.

First, What Is a Quill?

A traditional quill pen consists of a feather that has been trimmed to around 9 inches long, had its shaft stripped of barbs, and had the inside and outside of the hollow barrel cleaned of membrane and wax. The quill is then dried, typically by curing it in sand, and the tip is shaped into a nib with a channel split (cut) to hold the ink.

The earliest fluid inks were carbon-based black inks that are believed to have originated in China around 2700 BCE. Iron gallotannate (iron gall) ink eventually replaced carbon and became the primary ink used with quill pens from the Middle Ages until the beginning of the 20th century. Iron gall ink is a permanent, deep purple-black or blue-black ink that darkens as it oxidizes, and is made from iron salts and gallotannic acids from organic sources (such as trees and vegetables). The Codex Sinaiticus, written in the fourth century CE and containing the earliest surviving manuscript of the Christian Bible, is one of the oldest known texts written with iron gall ink.

Linguists estimate that human speech sounds first developed tens of thousands of years ago. MIT linguistics professor Shigeru Miyagawa proposes that verbal language may have been used in social situations around 100,000 years ago, while linguist George Poulos, author of On the Origins of Human Speech and Language, suggests human speech developed around 70,000 years ago. But these early languages were likely never recorded by hand, and it was only around 5,000 years ago that the first known written languages first began to take shape.

Ancient civilizations in regions around the world began to develop complex written language systems starting at least as early as 3200 BCE. While it’s difficult to pin down the exact origin of these languages given the limited archaeological evidence available, historians generally agree on a few early cultures that pioneered the use of written communication.

Sumerian

From roughly 4100 BCE to 1750 BCE, the ancient Sumerian civilization thrived across southern Mesopotamia (modern-day Iraq). The Sumerians developed the world’s oldest known writing system, cuneiform, which consisted of wedge-shaped characters carved into stone tablets. The script was later used to denote the spoken Sumerian language, in lieu of any sort of alphabet. The language started as an entirely logographic script, and evolved into a phonetic syllabic system to convey more conversational thought. The oldest known example of Sumerian writing first appeared in a group of administrative and educational texts dating to around 3200 BCE. Around 2500 BCE, the Sumerians produced the first known literature from any ancient civilization: religious works such as the Kesh Temple Hymn that focused less on real-world issues and more on mythological concepts. 

The now-extinct Sumerian language consisted of four vowel sounds (a, i, e, u) as well as 16 consonant sounds (b, d, g, ŋ, h, k, l, m, n, p, r, s, ś, š, t, z), and was one of the first known uses of grammatical concepts such as prefixes, infixes, and suffixes. By the year 2000 BCE, the language had faded to the point where it was no longer spoken, as new civilizations and languages emerged throughout the region. It enjoyed a brief resurgence for literary and liturgical purposes between 2000 BCE and 1500 BCE, but was mainly studied by scribes thereafter.

William Shakespeare’s timeless tragedy Romeo and Juliet first appeared in print in 1597. The play’s famous prologue presents a compelling tale about “a pair of star-crossed lovers [who] take their life” because of an “ancient grudge” between their households. It’s a captivating story of forbidden love that endures as one of the Bard’s most popular plays, inspiring countless iterations in theater and film. The story centers around the lovestruck Romeo and beautiful Juliet — two of the most famous characters in popular culture to this day. But were these young lovers based on real people?

The Capulets and Montagues May Be Based on Real Families

Though historians generally agree that Juliet Capulet and Romeo Montague were fictional characters, it’s possible that their feuding houses were based on real families in Verona, Italy, where Shakespeare set his famous tragedy. Today, travelers to Verona can visit landmarks around the city that may have inspired the playwright and his predecessors, including two residences billed as the Montague and Capulet homes, as well as Juliet’s tomb at the Franciscan monastery outside Verona. The veracity of these claims varies, however: While the monastery has been identified as the setting referenced in the final act of Shakespeare’s play, the tomb is a symbolic representation of the fictional Juliet’s burial place. The site now known as La Casa di Giulietta (Juliet’s House), meanwhile, is a 13th-century home that belonged to the Dal Cappello (commonly known as Cappelletti) family, who some historians believe may have inspired Shakespeare’s Capulets. In fact, the Bard borrowed the names of his “two households” from Dante’s Divine Comedy, an Italian narrative poem composed in the early 14th century. Dante’s poem is one of the earliest texts to reference the Montecchi and Cappelletti families (Italian equivalents for the names “Montagues” and “Capulets”), who were real-life rival political factions in the 13th century.

For as long as humankind has existed and suffered, we’ve also laughed. Humor — and jokes, specifically — have long been a part of socio-anthropological culture, whether as a way to poke fun at the powerful or just to be plain silly. Even toilet humor, however gross, has often played a significant role in day-to-day life, amusing and shocking listeners with taboo topics. From the earliest days of civilization, laughter has brought people together despite their differences, serving as a tool for both enjoying life and bonding with one another. Here are some of the oldest jokes in history, observations and witticisms that made people laugh thousands of years ago.

The Oldest Recorded Joke

The oldest joke on record dates back to 1900 BCE in ancient Sumer, the earliest known civilization in Mesopotamia. Rather than a conventional setup and punchline structure, the joke is more of an observation: “Something which has never occurred since time immemorial; a young woman did not fart in her husband’s lap.” The double-negatives throw in a bit of confusion, but the joke gets at a primary urge to hide certain imperfections from a romantic partner.

The First “Walked Into a Bar” Joke

The Sumerians are also credited with the first-ever “walked into a bar” joke, dating to around 1983 BCE. It goes: “A dog walks into a bar and says, ‘I cannot see a thing. I’ll open this one.’” Though we’re all familiar with bar jokes — and the odd characters and animals who just so happen to walk into them — no one can quite parse the meaning of this Sumerian joke, or why it was funny. There are amateur theories ranging from the Sumerians appreciating (as we do now) “random humor,” or the dog’s blindness being some kind of pun. Until we have a time machine, it’s likely to remain a mystery.
