Israel Knohl has some interesting theories concerning messianic ideas and figures before the development of Christology. Knohl, in this book geared toward the lay-person, tries to connect and identify a messiah, he believes was written about in the Dead Sea scrolls and how this view was influenced by Judaism and the struggle against the Rome and it's imperial cult. Knohl proposes the theory of a "catastrophic messianism" that played out in the persons of Menachem the Essene and Simon of Peraea in circa 4 BCE, during a revolt against Rome. He uses the DSS messanic texts 4Q49I, 4QHE, and 4QHa to base his assumptions concerning the reason for the supposed excommunication of Menachem the Essene and his followers.
Israel Knohl makes a lot of assumptions and tries to pair it with history. One of the sections I found most interesting was the influence Roman imperial cult had on the messianic texts of the DSS.
"The divine character of Augustus the redeemer is also clearly
expressed in the art of the period.31 In some artifacts Augustus is
shown sitting on a splendid throne in the company of the gods.32
The Messiah of the Qumran sect described himself as sitting
on a “throne of power” in the congregation of the gods,33 exactly
as Augustus is depicted. The messianic hymns from Qumran describe
the period of redemption in terms remarkably similar to
those in Virgil’s description of the new age. Because the Qumranic
Messiah was active during the period of Augustus, we must
consider the possibility that the political and cultural atmosphere
in Rome as expressed in Virgil’s poetry and Augustus’s propaganda
also influenced the Messiah." pg. 99
