The number 13 has been associated with bad luck for centuries. The Last Supper where Jesus gathered his 12 disciples might have originated this controversy. Among other superstitions people believed that if 13 people sat at a table, one would die within a year.
Nowadays many hotel lack floors numbered 13 and some Airlines skip row 13.
Reinforcing this reputation, on April 13, 1970, an explosion aboard the Apollo 13 spacecraft aborted the mission. However there is little historical evidence for fearing years ending in 13, despite Shakespeare´s Globe Theatre burning in 1613. For instance, 1913 wasn´t particularly tragic, considering the First World War started one year later. In 1813, Napoleon Bonaparte was conquering Europe.
