Once again, it's that dreaded date, Friday the 13th. On the whole, I can't say I've ever had a particularly awful day on that one, but everybody talks about it. Oddly enough, this superstition isn't all that ancient. Historians can't find any record of it before 1869. However 13 has been considered an unlucky number, and Friday in some cultures is an unlucky day, so perhaps it's just a combination of two older superstitions.
So spilled salt, broken mirrors, umbrellas opened indoors, walking under a ladder and black cats. Can anybody think of any other superstitions for bad luck? What about good luck? Horseshoes, rabbits feet, the number 7, found pennies (although I think that one dates from when finding a penny actually was good luck because you could buy something with it). A lot of athletes seem to have lucky shirts, lucky socks, etc. My husband has been fired twice in the same tie--he'll never wear a tie with ducks on it again.
Have you used superstitions or read about them in books? As an author, I do like to play around with expectations, and it's occurred to me to write a book where all the bad luck superstitions bring good things to the character and her lucky horseshoe falls on her toes. Meanwhile, I do think it's fun to read up on the folklore behind them.
Hope everyone has a lucky 13th!
