The superstition surrounding Friday the 13th as an unlucky day is a fascinating blend of Christian tradition, Norse mythology, medieval history, and modern pop culture. Here’s a deep dive into its origins:
1. Christian Origins: the Last Supper & Crucifixion
- 13 at the Table: in Christianity, 13 is linked to the Last Supper, where Jesus dined with his 12 apostles - making Judas Iscariot the 13th guest (the betrayer).
- Good Friday: Jesus was crucified on a Friday, turning it into a day of mourning in Christian tradition.
- Combined, Friday + 13 became symbolic of betrayal, suffering, and bad luck.
2. Norse Mythology: Loki’s deadly feast- In Norse legend, the trickster god Loki crashed a banquet of 12 gods in Valhalla, becoming the 13th guest. His presence led to the death of Balder, the beloved god of light, plunging the world into darkness. This reinforced the idea of 13 as a cursed number in European folklore.
3. The Templar Massacre (Friday, October 13, 1307)
King Philip IV of France ordered the arrest and execution of the Knights Templar on Friday, October 13, 1307, accusing them of heresy. The brutal suppression of this powerful order embedded Friday the 13th in history as a day of treachery and doom.
4. Victorian-era superstition & pop culture
- "Friday the Thirteenth" (1907). A bestselling novel by Thomas Lawson about a stock market crash tied to the date.
- Horror Films. The "Friday the 13th slasher franchise (1980–present) turned the superstition into a global pop-culture phenomenon.
Why do people still fear tt?
- confirmation bias: People remember bad events on Friday the 13th but ignore neutral/good ones.
- triskaidekaphobia: Fear of the number 13 (common in Western cultures where 12 is "complete," e.g., months, zodiac signs).
- paraskevidekatriaphobia: The actual term for fear of Friday the 13th!
By the way!
In Italy, 17 (not 13) is the unlucky number.
In Spanish-speaking countries, Tuesday the 13th (Martes 13) is feared instead.
