Popular, but untrue

It didn’t happen: 10 history myths that are regarded as true

A big part of history is dependent on who’s telling it, but some facts are indisputable. However, some stories have become so widespread —be it because of popular legend or by honest mistake— that most would assure them to be true. Some have even been transmitted for generations, but they happened in a different way or not at all. Let’s revise 10 historic "facts" that are just myths.

The idea that Viking helmets had horns is consistent with their fame as frightening warriors, but it is simply not true. This misconception is a result of 19th-century artists, such as Richard Wagner, and their interest in the Middle Ages, which, in many cases, involved inventing facts when reliable information was lacking. We now know that Vikings wore cap-like helmets with nose guards, and without any protruding elements.

The French Revolution and its rejection of the monarchy led to Marie Antoinette having a tarnished reputation, with many accusing her of not caring about her subjects and living an extravagant life while the French people suffered. The phrase ‘let them eat cake’, attributed to her, is a big part of this, but no matter how she actually behaved, we know as a fact that she never said it. This phrase was attributed to an unnamed princess by philosopher Jean Jacques Rousseau, but at that time, Marie Antoinette was 9 years old and still lived in Austria.

While the father of the nation did wear dentures, the widespread belief that these were made out of wood is not true. Historians have confirmed that his dentures were made from a mix of different materials, including ivory, human teeth, animal teeth, and metallic pieces. The idea that these were wooden is most likely a result of the brownish appearance of stained ivory.

Roman emperor Nero has a well-deserved reputation as a tyrant. He habitually murdered opponents, persecuted thousands of Christians, and was known to enjoy animal cruelty. However, there is no solid proof that he intentionally started the fire of Rome, although we know that he did nothing to stop it, and played music as he watched the city burn. The fire was most likely an accident, and Nero took advantage of it to rebuild Rome in grandeur.

Scholars have known the Earth is a sphere since classical antiquity, and medievals inherited that knowledge from the ancient Greeks. Why did they not travel to the West then? Is not that they thought they would reach the end of the world, but that they were unsure of the dangers of such a travel. The idea of medieval people as flat-earthers is a result of 19th-century writers' concept of the Middle Ages as a ‘dark time’ of ignorance.

To the surprise of many, the Continental Congress declared independence from Great Britain on July 2nd. But why is Independence Day not celebrated on that date? Founding Father John Adams asked the same question. While the voting was done on the 2nd, the document was finalized and distributed on the 4th, and most delegates adopted that date. John Adams wrote extensively about the importance of July 2nd, and he reportedly declined invitations to 4th of July celebrations in protest.

The Salem witch trials were undoubtedly outrageous, and modern historians believe that the result was mass hysteria. However, the idea that convicted individuals were burned at the stake is just a popular myth. 19 people were executed by hanging, and one other died during interrogation due to torture. In the years after, it was proven that evidence of witchery was fabricated, and the trials were declared unlawful.

While historians and chroniclers have several theories about Julius Caesar’s dying words, we know for a fact that he never said ‘_Et tu, Brute?’ (You too, Brutus?) to his adoptive son. This phrase was coined by Elizabethan playwright Richard Edes and later popularized by William Shakespeare. What did Caesar say instead? We don’t know, but the prevailing theories are that he remained silent or that he spoke in Greek and said ‘_καὶ σύ, τέκνον?" (‘You too, child?’).

When Rosa Parks refused to give up her seat, she knew she was making a political statement. However, contrary to what many believe, she was sitting on a part of the bus that African Americans were allowed to use. Why was she asked to give up the seat, then? She was sitting in a section that was for everyone, but where white people had priority. When the white section became full, she was asked to give up her spot. She refused, and the rest is history.

The story of Galileo Galilei’s trial is one of the most widespread historical myths, and most people are certain that he was tortured because of his beliefs and then executed. Galileo was indeed tried by the Church, but it was not the simplistic case of science vs. faith most believe it to be. In reality, it was a scientific debate and, while Galileo was ultimately right in defending Heliocentrism, he failed to prove it. After the trial, he received house arrest in a villa, where he died of natural causes.

Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
