Michael, I am curious. Who do you consider "heavy hitters"?
If you read my intro it is obvious I don't have anyone on the "heavy hitters" list who is contemporary. Richard Elliot Freidman comes close as he has been able to at least break away from standard Wellhausen theory and has been able to properly identify the real starting and stopping points of the orginal text. However, he fails to edit it properly. nor does he realize what he has.
I give points to Tigay for his work on Gilgamesh, but have to ask the question, "Once he discovered how Gilgamesh was composed, why didn't he apply the same techniques to the Bible?" He could have easily deconstructed the Bible text and blown Freidman away.
Thomas Thompson as a minimalist is on the list, but his writing is dry and vague. He at least has the kahaunas to state what the scholars really know, "there was no United Monarchy."
I like two dead people. One is Richard Hinckly Allen who wrote about how the ancients viewed the stars and constellations. I use him as "my Bible" in order to construct my work on cosmic myth interpretation. Anne Wright has a constelltion web site which quotes much of his work. His dating is way off as he wrote before the modern era of carbon dating etc.
Also A.H. Sayce was a fantastic author of ancient Babylon. I consider his views on the origin of Hebrew words and Bible persons to be the best out there, although modern scholarship has either ignored or rejected his ideas. His Lectures book is available in pdf. as a free download. I also sell printed copies at my lulu web page, if you are like me and need a book to hold in your hand and high light.
There are current authors who write about the Bible and astrology, but their work is amateur compared to my own. They primarily use the works of Gerald Massey. Massey was wrong in a number of areas, so where he makes mistakes, modern authors have failed to correct them, simply because they haven't bothered to research every regional myth about every star and constellation and come together with a viable story with respect to archaeology, and most important. "what did they believe and when did they believe it." They ignore the fact the Hebrews had a 10 zodiac signs, not 12 and the Hebrews considered the Pleiades as part of Aries and not Taurus. These are amateur mistakes you can find in other author's works, but not mine.
