1 Enoch?

In 1 Enoch, the Book of the Watchers, the historical background seems to be set during the Diadochan Wars around the third century B.C.E. I was wondering if anyone knew of some sites that would have some more info. on this period specifically regarding the culture of this time.

This would be of great help because I am writing a paper on 1 Enoch dealing with the text’s historical background during the time of the author and the text’s role in the symbolism and repetition of certain motifs, along with the interpretation of certain scenes within it.
