I think it was dated at the end of the Domitian era? AD 81 or a little later. Fall of the temple was what AD 70?
Something like that.
Dated by whom, based on what?
You might want to look into that. Most believe John, writing from the island of Patmos, wrote Revelation very early. You can clearly see the other writers of the New Testament using John’s words in their letters.
This was a revelation to me (pun intended) because in my mind John was in his later years, but in fact, based on whom was in positions of power, John wrote Revelation very early.
As a side note, if you don’t already know, Isaac Newton wrote extensively about the Bible. He was a devout Bible reader. You can read his works here: http://www.newtonproject.sussex.ac.uk/prism.php?id=1. There are actually two groups working to get his papers online.
Read the history of how Newton’s papers came to light. It is, to me, fascinating considering not all Newton’s papers were available until after 1939 when Maynard Keynes (yes, that Keynes) and Abraham Yahuda obtained them at auction. Yahuda’s papers were donated to Israel for their library.
