If you could provide any single writing or more, from the historians that lived at that time ... say from Flavius Josephus, a Jewish historian, and Tacitus, a Roman historian.... both of whom were alive in 70AD and it was Josephus who wrote about events in that period.... Tacitus no. Tacitus the Roman historian who wrote about the Roman Empire and its events. But not yet active as a historian in 70 CE, though he did live during this time.
And last but certainly not least Polycarp... who was a disciple of the Apostle John. Even being born around the year 69AD should have certain insights and knowledges he learned as an historian and a diciple of John... so I will post him last
if any of these support the And common preterist belief that Jesus came back then was fact, I might be persuaded that was when the great tribulation happened.
So what do of them say about such a thing.
Ill start with Tacitus.... as he did not start until after the 70AD period....and likely has less to say then Josephus
This paper considers how Tacitus may have portrayed the destruction of the Jewish Temple in Jerusalem in the now-lost portion of the Histories, and how this might have affected readers’ experience of the Histories as a religious narrative.

The above is what I could find on what Tacitus writing about the time had to say...
Now lets see what Flavius Josephus wrote as he was writing before 70AD
Ai ~ Josephus wrote that the destruction of the Temple in 70 AD was a result of Jewish sins and a sign that God had turned to the Romans, emphasizing the need for Jewish repentance. He did not claim that Jesus returned at that time; rather, he focused on the political and religious implications of the Temple's destruction for the Jewish people.
Preterism is an increasingly popular view of the second coming of Christ. Is it true, did Josephus reveal Christ returned in A.D. 70?

So far we have only speculation and guesswork as to if the signs really happened and if any biblical signs happened.
POLYCARP
Polycarp was a disciple of the Apostle John, and is considered one of the Ante-Nicene Church Fathers. His writings provide insight into early Christian beliefs regarding eschatology, particularly concerning the return of Jesus.
Ai~ Polycarp, an early Christian writer, hinted at a future coming of Christ in his writings, indicating that he did not believe the return of Jesus occurred in 70 AD. His references suggest that he viewed the events of the second coming as still to come, rather than having already happened.
Why Did the Disciples of the Apostles like Polycarp Teach a Future Resurrection Beyond A.D. 70?
It eems from other sources that the tribulation mentioned by Jesus was not the future Great Tribulation.
There is not much from Polycarp on this subject of 70AD...but he was into the future coming of Jesus and that is where his teaching lay.
