History of Friday the 13th

What's there to be afraid of?

If you’re reading this article to learn the history of Friday the 13th, you’re in luck.

Or perhaps bad luck.

No one knows, with any certainty, when it began or why it’s to be feared. However, there are lots of entertaining speculative theories about the topic.

What is the Fear of Friday the 13th?

• Paraskevidekatriaphobia — is the name of the superstition. The word is constructed from the Greek words Paraskeví (Παρασκευή), meaning “Friday,” and dekatreís (δεκατρείς), meaning “thirteen.”

• Friggatriskaidekaphobia — is the fear of Friday the 13th. The word has both Norse and Greek roots: Frigg or Frigga, the name of the wife of the Norse god Odin. Friday gets its name from Frigg. Triskadeka is “thirteen” in Greek (literally: “three” and “ten”), and phobia means “fear.”

12 is completeness, 13 is useless

Twelve is considered complete in many cultures. Mathematically, it can be divided into halves, thirds, and quarters. You can’t do that neatly with Ten.

Examples:

• 12 tribes of Israel

• 12 days of Christmas

• 12 hours in a day

• 12 months

• 12 Zodiac signs

• 12 gods of Olympus and Norse mythology

Thirteen is a dubious number, and Friday has gotten a bad rap. Add them together, and you get Friday the 13th.

There are several ominous Fridays in the Bible.

Friday the 13th in Mythology

• The Old Norse story is told about the twelve Nordic gods dining in Valhalla when an uninvited guest, Loki, the god of mischief, joined the group, making it 13.

Friday the 13th in History

• An early story suggested that the fear of 13 came from one of the world’s oldest legal documents, the Code of Hammurabi, which predated even the 10 Commandments. Supposedly, the Code omitted a 13th law from its list of legal rules. (However, the omission was merely a clerical error made by one of the document’s earliest translators, leaving out a line of text. The Code doesn’t even numerically list its laws.)

• The Fall of Constantinople in the Fourth Crusade occurred on Tuesday, April 13, 1204

• On Friday, October 13, 1307, Philip IV of France arrested hundreds of Knights Templar to seize their financial assets. They were subsequently burned at the stake. Grandmaster Jacques De Molay cursed Philip before his execution. The author Dan Brown popularized this story in The DaVinci Code.

“On a Friday fell all this mischance.”

When Did Friday The 13th Become Popular?

• While it was recognized in late Victorian England, it really took off in the early 20th century. In 1907, Thomas Lawson wrote a book called Friday, the Thirteenth.

• In the 1980s, a series of Paramount Pictures Friday the 13th films began, with the antagonist Jason slashing his way through summer camp.
