Why Italians Dread Friday the 17th — While the Rest of the World Fears the 13th

Sharing is caring!

Millions of people fear Friday the 13th. In Italy, no one bats an eye. The number they dread is 17. Hotels skip room 17. Some airlines remove row 17. Buildings quietly jump from floor 16 to 18. And if a Friday falls on the 17th, many Italians treat it as the worst day of the year. This is one of Italy’s most enduring superstitions — and most visitors never even notice it.

The Ancient Roman Secret Behind the Number 17

The fear has a very specific origin. In Roman numerals, 17 is written as XVII. Rearrange those four letters and you get VIXI. In Latin, vixi means “I have lived.” The past tense matters enormously. It was a phrase carved on Roman tombstones to mark that someone had died. XVII was not just a number. It was a funeral inscription.

This connection stuck. For over 2,000 years, the number has carried that shadow in Italian culture. No one needed to be taught the superstition. It was simply absorbed, generation by generation, through the ruins and churches and family stories that surround Italian life.

When you see the number 17 on a hotel door or a lottery ticket, some part of Italian memory makes a quiet note. The ancient Roman word for death is still there, hidden inside the digits.

Why Friday Makes Everything Worse

In most of the world, Friday the 13th carries the unlucky reputation. In Italy, Friday itself has a cautious history. It is the day of the Crucifixion in Christian tradition, and Italian culture has long associated it with misfortune. So when Friday lands on the 17th, two bad omens arrive together.

Some Italians will not travel on this day. Others avoid signing contracts, starting new jobs, or planning weddings. Builders have been known to pause work. Supermarkets sometimes see a slight drop in sales. It is not universal. But it is common enough to be noticeable if you are paying attention.

This day is known as Venerdì 17. It has the same cultural weight in Italy that Friday the 13th holds elsewhere. Several Italian films have used it as a storyline. The country’s version of the Friday the 13th horror franchise even renamed it for the Italian market — because the original date simply was not scary enough.

The Evil Eye That Italians Still Take Seriously

Italian superstitions do not stop at a single number. The malocchio — the evil eye — is one of the oldest beliefs in Italian culture, and one of the most widely held. The idea is simple: a look of envy or jealousy from another person can bring you bad luck.

You do not need to have done anything wrong. The person looking at you does not need to wish you harm deliberately. An envious glance at your new car, your healthy child, or your good fortune can be enough. The effect is invisible and slow. You might not connect it to anything for weeks.

The belief is especially strong in southern Italy. Older generations take it seriously. Many younger Italians say they do not believe in it — but still follow the old habits without really thinking about why.

The Cornicello: Italy’s Most Visible Lucky Charm

The most common protection against the evil eye is the cornicello. This is a small twisted horn-shaped charm, usually red or gold. You see them everywhere in Italy: hanging in shop windows, swinging from rear-view mirrors, worn as pendants. They are one of the most common souvenirs tourists bring home without fully understanding what they mean.

The horn has ancient roots. Some historians link it to fertility symbols from pre-Roman cultures. Others connect it to the shape of an animal horn, which many ancient peoples believed could deflect evil. The colour matters too. Red is considered the most powerful. Gold is decorative but still carries meaning.

A broken cornicello is not thrown away carelessly. It is said to have absorbed all the bad energy it could hold — which is why it broke. The correct thing to do is bury it or throw it into the sea. You can read more about the cornicello and its role in Italian daily life — it is one of the most visible symbols you will encounter on any visit.

Olive Oil, Hats, and the Other Things Italians Avoid

Italian superstitions extend well beyond the number 17. They cover ordinary moments that most people never think about. Spilling olive oil is considered very bad luck — worse than breaking a mirror in many parts of Italy. The oil has sacred associations that go back centuries.

Placing a hat on a bed is said to invite death into the house. Opening an umbrella indoors brings misfortune. A black cat crossing from left to right is bad luck. Right to left is neutral or even positive, depending on which region you are in. These rules are not standardised. They vary from town to town and family to family.

Not every Italian superstition brings bad luck. The number 13 is actually considered lucky — the direct opposite of how English-speaking countries treat it. Receiving a lucky charm as a gift is more powerful than buying one yourself. And a sincere, well-meant wish from someone who loves you is believed to carry real weight in the world.

Naples: The City That Kept the Old Beliefs Alive

No city in Italy holds onto its superstitions more openly than Naples. The city has deep roots in Greek, Roman, and Spanish culture. Each left behind its own ideas about luck, fate, and the invisible forces that shape a life. In Naples, all of those layers still exist at the same time.

You will find cornicelli sold alongside mobile phone cases. Grandmothers make the sign of the horns — index and little finger pointing down — while checking messages on their phones. People say “toccacornicello” (touch the horn) the way others say “touch wood.” There is no irony in it. It is simply how things are done.

The café culture of Naples is deeply tied to this world. Coffee is drunk standing at a bar, news is exchanged, and the old superstitions pass between generations not through formal teaching but through habit, conversation, and repetition. Nobody decides to believe. They just find that they do.

What Visitors Actually See on the Ground

If you travel in Italy on a Friday the 17th, nothing alarming will happen. Restaurants are open. Museums run their normal hours. The streets look the same. But if you know what to look for, you may notice small things: a business owner who delays opening the shutters, a driver who takes an extra moment before pulling out, someone who quietly says “meglio non rischiare” — better not to risk it.

You will see cornicelli in almost every car. You will notice them in market stalls in Naples, Rome, and Palermo. In older homes, you may see them pinned near the door alongside a small holy image. These two things — the religious and the superstitious — have lived side by side in Italy for so long that no one finds the combination strange.

Understanding Italian superstitions does not require believing in them. It requires recognising that they are a real part of Italian daily life. When someone you meet in Italy touches iron instead of wood, or hesitates before booking a date, they are not being irrational. They are following a very long thread back through history.

Italy’s superstitions are a window into how this culture has always understood the world — not as something fully predictable, but as something that can be nudged, protected against, and approached with care. That is not such a strange idea, when you think about it.
