In Biblical tradition, the concept of unlucky Fridays, stretches back even further than the crucifixion: Friday is said to be the day that Adam and Eve ate the forbidden fruit from the Tree of Knowledge the day Cain murdered his brother, Abel the day the Temple of Solomon was toppled and the day Noah’s ark set sail in the Great Flood. Dan Brown's 'The Da Vinci Code' popularized the erroneous theory this is the original of the Friday the 13th superstition. Hundreds of the Knights Templar were arrested on October 13, 1307, and many were later executed.
