reference to the number identified with the Antichrist. Antichrist is a Biblical
term often identified with a
beast which has 7 heads and 10
horns described in the
Old Testament, who is supposed to betoken (be a sign of) the end of the
world. According to the
Bible, when the Antichrist becomes visible on Earth, he will require everyone to be tattooed with a certain
mark on the
right hand or on the forehead in
order to get a
job or
buy anything. The
mark of the
beast is either the name of the creature or the number 666Na
code number which the numerical
values of the letters in the
beast's name are said to add up to.
