Many others of a later age could be cited supporting this same connection between John and Domitian, but it would seem that this does no more than to continue a tradition which appears to have come from the language of Irenaeus. The conclusion most come to at this point is that the external evidence of John writing the Apocalypse at the close of Domitian's reign rests on the sole testimony of Irenaeus, who wrote a hundred years after that date, and whose words were from a verbally transmitted second source during the childhood of Irenaeus. To make matters worse, the words he used can easily have two different meanings!
An ancient document known as the Muratorian Canon which comes down to us from AD 170–210 states, "Paul, following the order of his own predecessor John, writes to no more than seven churches by name." The seven churches that Paul wrote to were: Rome, Corinth, Galatia, Ephesus, Philippi, Colossi and Thessalonica. John, in his addressing the writing of Revelation, wrote to seven churches as indicated in Revelation 1:4. The implication of this statement in the Muratorian Canon is that John had written his book of Revelation BEFORE the completion of Paul's writings to the seven churches he had written to. Paul died under Nero's persecution. Nero's rule ended in AD 68!
Clement (AD 150–215) makes the following statement supporting an early dating: "For the teaching of our Lord at His advent, beginning with Augustus and Tiberius, was completed in the middle of the times of Tiberius.
And that of the apostles, embracing the ministry of Paul, end with Nero" (Miscellanies 7:17). Clement seems to indicate that he believes that the Scriptures were completed by the end of Nero's reign which ended in AD 68.
Epiphanies, AD 315–403, stated that the book of Revelation was written under Claudius [Nero] Caesar. This Roman ruler was emperor from AD 54 to AD 68.
Andreas of Capadocia, about AD 500, in a commentary on Revelation, dates the book as Neronian.
Arethas, about AD 540 assumes the book to have been written before the destruction of Jerusalem and that its contents was prophecy concerning the siege of Jerusalem.
There is no shortage of those from the above date forward who support the earlier dating of the book of Revelation.

Alfred Edersheim in his book, The Temple: Its Ministry and Services, Books for the Ages, Albany, Oregon, 1997, states on pages 95 and 96 that the internal evidence of the book of Revelation points to a date prior to the destruction of Jerusalem for the writing of Revelation.
Philip Schaff in his work History of the Christian Church, Eerdmans Publishing, Grand Rapids, Michigan, vol.1, p. vi writes "...the date of the Apocalypse (which I now assign, with the majority of modern critics, to the year 68 or 69 instead of 95, as before."
Robert Young, who authored "Young's Analytical Concordance, wrote a commentary on the book of Revelation which was published about 1885. In that work, Young makes the following statement:
"It [the book of Revelation] was written in Patmos about A.D. 68, whither John had been banished by Domitius Nero, as stated in the title of the Syriac version of the book; and with this concurs the express statement of Irenaeus in A.D. 175, who says it happened in the reign of Domitianou - i.e., Domitius (Nero). Sulpicius, Orosins, etc., stupidly mistaking Dimitianou for Domitianikos, supposed Irenaeus to refer to Domitian, A.D. 95, and most succeeding writers have fallen into the same blunder. The internal testimony is wholly in favor of the early date."
