Zero – the figure or symbol 0, which in the Arabic notation for numbers stands for the absence of quantity
Zero describes nothing, like how much extra money I have. The number zero as we know it arrived in the West circa 1200, most famously delivered by Italian mathematician Fibonacci (aka Leonardo of Pisa), who brought it, along with the rest of the Arabic numerals, back from his travels to North Africa.
In the Textus Receptus manuscripts of the New Testament, the Book of Revelation (13: 17–18) cryptically asserts 666 to be “man’s number” or “the number of a man” associated with the Beast, a hostile creature that appears briefly about two-thirds into the apocalyptic vision. 666 has become one of the most widely recognized symbols for the Antichrist or, alternatively, the devil.
