What is the origin of the Friday the 13th superstition?
There are many theories regarding the origin of Friday the 13th. Some people actually suffer from a sever phobia of Friday the 13th. This phobia is called paraskevidekatriaphobics.
LEGEND HAS IT: If 13 people sit down to dinner together, one will die within the year. The Turks so disliked the number 13 that it was practically expunged from their vocabulary. Many cities do not have a 13th Street or a 13th Avenue. Many buildings don't have a 13th floor. If you have 13 letters in your name, you will have the devil's luck (Jack the Ripper, Charles Manson, Jeffrey Dahmer, Theodore Bundy and Albert De Salvo all have 13 letters in their names). There are 13 witches in a coven.
One theory that attempts to explain the fear of the number 13 is primitive man. Man has only 10 fingers and two feet (I guess he did not count his toes) which equals 12. They were fearful of what came after this number.
Here is another theory. There were 13 people present at the Last Supper which took place on a Friday.
Another legend states that there were 12 Gods present at a banquet in Valhalla. An evil God (the 13th) showed up and raised a great deal of mischief.
The list goes on and on.
