However, if a figure as respected as David Pingree supports a sudden emergence view maybe I better not reach any hasty conclusions. Great scholar as he was I suspect the more recent research of people like Francesca Rochberg has possibly overtaken his research on this. What particular source by Pingree sets out his views on this? Its probably very hard to get a hold of like most of Pingree's research but it would be good to know at least.
Pingree's 1997 book 'From Astral Omens to Astrology' outlines his views on the matter pretty well.
Agreed this is really the crux of the debate. Well thats quite a few things already! It seems to me its quite possible that the ascendant degree and houses arose in a late Babylonian astrology (Seleucid dynasty) cross fertilised by hellenistic ideas. I will add back in the exaltations too which you omitted from the above list. I am aware Demetra George, Robert Schmidt and yourself have called into question this assumption and suggested a hellenistic origin.
I omitted it because I still consider it to be somewhat of a murky issue in which I feel that some assumptions are being made. The point about the exaltations is just that the assumption that they corresponded to the Mesopotamian 'secret places' predates the publication of the majority of the birth charts, and no one has really offered a plausible explanation as to why the birth charts don't fit the pre-established assumption. The Hellenistic concepts tied into the exaltations raise additional issues, but that is almost beside the main point, which is that the technical meaning of the bit nisriti in the Cuniform horoscopes is still unknown to this day. People are free to go ahead and assume that the exaltations and the bit nisriti are one and the same, but in making such a blanket assumption across the board I fear that this requires them to overlook a glaring contradiction which still needs to be addressed, one way or another.
Rochberg's research points to other areas such as basic aspects and the triplicities although I know you dispute this too.
No, I do not dispute Rochberg's point that the grouping of the triplicities is derived from Mesopotamian sources. What I disputed was her sloppy use of technical terminology in order to convey her argument, which consequently made it look like she was arguing for something that she was not. The article that I wrote addressing this issue can be read at this address if anyone is interested:

It was originally simply a post on a Kepler College discussion board during a class on ancient history with Nick Campion, Lee Lehman and Rob Hand. One of the reading assignments that week was a long paper on Mesopotamian astrology by Campion. In the paper Campion made the statement that recent evidence indicated that the Mesopotamians used the 'trine aspect', citing something that Rochberg had written.
When I went back and read the Rochberg paper it became clear that what she was actually arguing was that the Mesopotamians had developed the concept of the triplicities, or grouping of the signs into four sets of three, and she explicitly rejected that they had a geometrical conceptualization of 'aspects'.
The confusion in Campion's article was derived from the fact that Rochberg mixed up the modern astrological terminology that she was using to refer to the techniques, by saying 'trine' when she meant 'triplicity'. To some extent this is understandable since the same Greek term is used to refer to both concepts, and only context allows one to differentiate, but it is still mistaken for people to go around saying that that the Mesopotamians had the 'trine aspect' based on that paper. That is certainly not what Rochberg intended, and my statements were merely meant to draw attention to the issue so that it could be clarified.
I even have a theory that the Thema Mundi (at least in very rudimentary form) might be Babylonian in origin.

I know such a view would be regarded as heresy in some hellenistic astrological circles.
Elements of earlier Mesopotamian and Egyptian traditions have already been identified by Demetra George and others such as Bouch?-Leclerc a while ago, so I'm not sure that it would necessarily be regarded as heresy, although I guess that it depends on the degree to which one sees earlier origins as being relevant to some of the ways in which it was applied in the later tradition.
