Don't know if we can trust this site or not, but here's a quote, this was taken from a random google I did:
NumberMan
Caesar Neron
Nero was the Roman Emperor who persecuted the Christians. Some say he was the person whom John was referring to in Revelation. I don't recall anything in the history books about him enforcing a mark of the beast.
The actual Greek rending of this name doesnt even come close to 666. If we use Hebrew then it depends on how we spell out his name. This is the correct way to spell Caesar Neron as written in Greek.
Καισαρι Νερωνι (Greek Gematria)
Caesar Neron
342 +
1015 =
1357
Here is the Hebrew spelling of the name:
קיסר נרו (Hebrew Gematria)
Caesar Nero
370 + 256 = 626 (If you drop the Yud from קיסר then you would have 616, but that's not how Caesar is spelled in Hebrew)
Some use an alternate spelling of his Name/Title such as קסר נורן which does total to 666. So is it Nero נרו or Neron נורן, Caesar קסר or קיסר? This will obviously adjust the values there.
There are Final Letters such as Nun, Mem, Tzadik, Peh, and Caph. Some choose to use the Sofit values of those letters and others don't. Early Hebrew didn't have final letters as this is more modern Hebrew dating back to about the 2nd century CE.
Revelation was written in Greek therfore it would seem strange to use a Hebrew calculation to come up with the value of 666/616 for his name.
One missed detail with the Nero scenario is the timing of his rule with the authorship of Revelation by John.
Nero ruled Rome from 54-68 A.D. Revelation's estimated authorship is upwards of 20 or more years beyond his rule. Now if Revelation is thought to be prophetic it wouldn't make sense claiming Nero as the Antichrist since he had already died many years before. Therefore dont push aside the idea we have another one coming whom will have a much greater influence then a Roman Emperor who lived 2,000 years ago.
Of course weve also noted above that this could mean Number of Man not just the Number of a Man such as Nero or whomever else should come to fullfill this role.[end quote]
I think Luther, Calvin and many others had it right. Nero seems like one of many persecutors of the church but never claimed to be of the faith, or a prophet, he didn't deceive with signs and wonders either.
At least I don't believe he did.
