The Roman numeral for 666, DCLXVI, has exactly one occurrence of all symbols whose value is less than 1000 in decreasing order (D = 500, C = 100, L = 50, X = 10, V = 5, I = 1).
Number of the Beast
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" (depending on how the text is translated) associated with the Beast, an antagonistic creature that appears briefly about two-thirds into the apocalyptic vision. Some manuscripts of the original Greek use the symbols χξϛ chi xi stigma (or ϝ digamma), while other manuscripts spell out the number in words.
In modern popular culture, 666 has become one of the most widely recognized symbols for the Antichrist or, alternatively, the devil. The number 666 is purportedly used to invoke Satan. Earnest references to the number occur both among apocalypticist Christian groups and in explicitly anti-Christian subcultures. References in contemporary Western art or literature are, more likely than not, intentional references to the Beast symbolism. Such popular references are therefore too numerous to list.
It is common to see the symbolic role of the integer 666 transferred to the digit sequence 6-6-6. Some people take the Satanic associations of 666 so seriously that they actively avoid things related to 666 or the digits 6-6-6. This is known as hexakosioihexekontahexaphobia.
- In the Bible, 666 is the number of talents of gold Solomon collected each year (see 1 Kings 10:14, 2 Chronicles 9:13 and also in Ezra 2:13).
- In the Bible, 666 is the number of Adonikam's descendants who return to Jerusalem and Judah from the Babylonian exile (see Ezra 2:13).
- In the Bible, there may be a latent reference to 666 in the name of the great sixth-century BC king of Babylon. Commonly spelled Nebuchadnezzar, transliterating from the Book of Daniel, the name is Nebuchadrezzar or Nebuchadrezzur in the Book of Jeremiah (see Jeremiah 49:28–30). The number of each name can be calculated, since Hebrew letters double as numbers (see Gematria, Hebrew numerals). Nebuchadrezzar is 663, and Nebuchadrezzur, 669. Midway between the two variants is 666. If the mysteries of Jeremiah are to be related to those of Revelation, Nebuchadrezzar, who came (though bidden by God) to crush God's people, may prefigure the end-times beast.
- Using gematria, Neron Caesar transliterated from Greek into Hebrew produces the number 666. The Latin spelling of "Nero Caesar" transliterated into Hebrew produces the number 616. Thus, in the Bible, 666 may have been a coded reference to Nero the Roman Emperor from 55 to 68 AD.
