All the research in the world is a moot point if the internal evidence in Revelation doesn’t agree with it.
I like digging into history as well as you do, but in this case, I would agree with your last link (Wilson) that Domitian’s reputed persecution of the Christians has been historically inflated in scope.
But instead of trying to figure out which emperor was reigning when Revelation was being written, we should be asking which of the seven “kings of the earth” (a term Christ used for Jerusalem’s high priests in Matt. 17:25) was then serving as John was writing. This was the one former high priest of the 7 “kings of the earth” who “IS” still presently alive as John was writing Rev. 17:10.
One of these 7 high priest “kings of the earth” had not yet come into office for that abbreviated “SHORT SPACE” of time. This was going to be Ananas ben Annas, who would be kicked out of his appointed office of high priest after only serving 3 months in AD 63. Meaning Revelation had to have been written prior to Ananas’s high priestly appointment in AD 63.
Revelation 17:8 described the brief period of re-instated existence for that Scarlet Beast (with its eight high priest “kings”). This Scarlet Beast was “ABOUT TO ARISE out of the abyss and go into destruction” soon after John wrote his apocalypse.
I’ve discussed these seven and eighth “kings of the earth” (the high priests of the land of Israel) on several posts before. They were the eight high priest members of the family of Annas, serving in turn almost continuously from AD 6 through AD 66. Theophilus was the one former high priest who was still alive (the one who “IS” when John was writing). We know Theophilus was still alive because Luke was writing to this former high priest, the “most excellent Theophilus”, some time around AD 62.
Since no high priest “kings of the earth” have ever served since the end of AD 70, that means Revelation’s prophecies that mentioned those “kings of the earth” were describing events that would take place while there were still high priests around to perform those activities. Meaning Revelation had to have been written sometime before AD 70’s end with its destruction of the high priesthood.
One point that is confusing your link’s authors is the number of those with the name of “John” serving in the early church. There was the elder “John surnamed Mark” who I believe was probably the one serving in the Ephesian church after AD 70 had come and gone.
Then there was “John Eleazar” (the resurrected Lazarus), the “beloved disciple” who wrote the book of Revelation, and who survived being boiled in oil by the Ephesian governor at Nero’s orders. (Duh, you can’t kill resurrected people.)
Neither of these two men named John should be confused with the other disciple John, the son of Zebedee, who was martyred as well as his brother James. John son of Zebedee was NOT the one known as the “beloved disciple”. We can prove this by studying John 21.
It appears that confusion has historically reigned over just which of these men named “John” was being credited as the author of Revelation. Which consequently confuses the dating of Revelation also.
