Unlucky Things

This is the category most people picture first when they hear the word "superstition": the broken mirror, the ladder you shouldn't walk under, the salt you shouldn't spill, the number 13. What's genuinely surprising once you dig into the real history is how many of these feel ancient but are actually much newer, or much more specific, than the popular version suggests.

Newer than you'd think

Friday the 13th as a single combined unlucky date is a 19th-century development, not an ancient one — the Friday-is-unlucky tradition and the 13-is-unlucky tradition existed separately for much longer before being merged into the specific date people dread today. Wearing an opal that isn't your birthstone traces almost entirely to a single 1829 Walter Scott novel, Anne of Geierstein — a rare case where we can say, with real confidence, that a specific work of fiction manufactured a superstition rather than recording an existing one.

Often reversed elsewhere

Several "universal" bad-luck rules in this category are regionally specific rather than global. Spanish-speaking countries dread Tuesday the 13th, not Friday. Italy singles out Friday the 17th instead. Breaking a glass is bad luck in the mirror sense but is deliberately good luck at a Russian celebration ("na schastye") and at a Jewish wedding — the same physical act, read in opposite directions depending on the specific glass and the specific context.

We separate weak evidence from strong evidence, explicitly

Some popular origin stories in this category — the ladder-as-sacred-triangle claim, for instance — are weaker than commonly repeated. Where a widely-shared explanation doesn't hold up, we say so and give the better-supported alternative equal or greater weight.

Some of the best-documented origin chains on the whole site

This category also holds some of the strongest evidence anywhere on TheOmenBook. The seven-years-bad-luck rule for a broken mirror traces to Roman belief that the soul renews itself every seven years, layered on top of a much older pre-glass practice of scrying with polished metal and reflecting pools. Saying "Macbeth" in a theatre carries a specific, well-documented superstition and an actual, still-performed cleansing ritual among theatre professionals — living folklore, not a museum piece.

Practical origins hiding in plain sight

A few beliefs here have a genuinely mundane practical root that got layered over with superstition later. Opening an umbrella indoors was a real, practical hazard with Victorian-era spring mechanisms, quite apart from any symbolic reading. We try to give the practical explanation its due alongside the folkloric one rather than picking whichever version sounds more interesting.

Frequently Asked Questions

Is Friday the 13th actually an old superstition?+

The combined date is surprisingly modern — a 19th-century pairing of two separately older beliefs (Friday as an unlucky day, 13 as an unlucky number) rather than an ancient tradition in its own right.

Why do some 'universal' bad-luck rules not apply in other countries?+

Because most Western unlucky-day and unlucky-number beliefs are regional folk traditions, not global constants — Italy's dread of Friday the 17th and the Spanish-speaking world's Tuesday the 13th are the clearest examples that the specific date, not just the concept of an unlucky day, varies by culture.

Is breaking a glass always bad luck?+

No — it's a good example of how context-dependent this whole category is: bad luck in most Western tradition, but read as good luck ("na schastye") in Russian celebration custom and at a traditional Jewish wedding.

Are theatre superstitions part of this category?+

Yes — saying "Macbeth" in a theatre and whistling backstage both have real, still-observed professional rituals attached to them, distinct from the general household unlucky-thing beliefs covered elsewhere in this category.
