I just finished watching the tape. Had chorus with my dd's this morning, then lunch. It was supposed to be re-broadcast at 2AM last night and dh couldn't get the timer to work, but between him and dd they got it taped. It finally came on at an odd time, like 2:35 or something. For once I am glad they are night owls.
So, I thought it was good, for an hour show. Some of the impt authors in the field, Pagels, Starbird, one of the authors of Holy Blood Holy Grail, and of course, Dan Brown the author of The Da Vinci Code, were interviewed.
Also a couple pastors and priests, theologians and art historians.
Most of the info was familiar to me. They did not delve deeply enough into the legends in Southern France about St Sarah the Egyptian, and the huge prevelance of black Madonnas there. Apparently there are dozens of churches and shrines dedicated to MM and St Sarah there. (That legend goes that after Jesus' death and resurrection, MM was taken by boat, along with a few other disciples, first to Egypt, then to Provence, to escape persecution by enemies of Jesus. She was supposed to be pg or already to have had their child[ren] by then. St Sarah could have been their "black" child, as MM may have been Egyptian herself in the first place. There was no town of Magdala on Lk Galilee back then [nor a Nazereth for that matter]. Magda, or a similar word, means tower in Hebrew, ie: pertaining to her as a tower of faith. You could say, Mary the Great.)
So, the show covered the fact that the Holy Grail (chalice, wine cup) was not depicted in Da Vinci's painting Last Supper, as the grail was MM herself, depicted on Jesus' right hand in drag as young John "the Evangelist." Da Vinci being a believer in this heresy, as were Botticelli and other Florentines of the day. The grail was supposed to hold the holy blood, as Mary as the "vessel" of Jesus' bloodline, would have done.
There was some good coverage of the gnostic gospels pertinent to this topic, the Gospel of Mary (Magdelene) and the Gospel of Philip.
There was a brief touching on the role of the Knights Templar as protectors of the Holy Grail and the Grail family.
There was nothing about the Cathar Inqusition and extermination.
And the final points were made that Mary M was more impt in the early centuries of the church, as the Catholics still call her, the apostola apostolorum (Apostle to the Apostles), but was later discredited as a prostitute. (Altho the idea of a prostitute does fit in to the gnostic myth of Sophia, IMO.) And finally, in the 20th century, cleared of this appelation.
