You are absolutely right: if we accept that premise (first formulated, as far as I know, by Ptolemy), then applying rulerships in the sidereal zodiac makes no sense -- and neither does applying those same rulerships in the tropical zodiac when casting charts for the southern hemisphere. But I don't see that Ptolemy's logic is very compelling to begin with. The association of the Sun with heat is natural, but why the Moon? And shouldn't the actual solstice point then fall in or close to the Sun's sign, rather than at the demarcation point between the signs ruled by Mercury and the Moon?
Right, it's a big if. I don't deny that, nor do I deny that it raises theoretical problems with a southern hemisphere perspective. These are all valid considerations. However it doesn't address the issue of domicile rulership in a sidereal scheme. I'm not fully aware of the entire history of domicile rulership, but to the best of my knowledge we have no (that we know of) examples of domicile rulership explicitly mentioned in the babylonian sources - though we may infer from it that they were aware of domicile dignity? I do not know enough about this to accurately make any statement one way or another. However we do know that the hellenistic astrologers were using domicile dignity, but what was the logic that it was based upon if not Ptolemy's?
I personally find a model, even if it takes some imagination to be more compelling than no model whatsoever. Is there a model that the sidereal astrologer would put forward to explain the logic behind domicile rulership?
I always saw the idea as less to do with heat as first and foremost to do with light. So the luminaries being the brightest objects were given the brightest months, though it is, admittedly, baffling why the brighter of the two, the sun, shouldn't get the cardinal sign. Either way, is there a sidereal logic that makes sense?
As I said in an earlier post, there is no 'correctly' or 'incorrectly' to it. Saying that Aries coincides with the equinox, or that it begins such-and-such a number of degrees before it, are stipulative definitions. The point is that you can't have a purely tropical zodiac and then miscalculate the distance between its zero point and the equinox. In order to say that the equinox falls at 8? or 10? or 15? of Aries, you must have a different, visible point of reference for the beginning of Aries. In other words, such a measurement can only arise in a conceptually sidereal zodiac.
Right, but I thought that's what they were talking about? Maybe I've misunderstood this all along. I always thought it was that the hellenistic, for the most part sidereally defined, astrologers were calculating the equinoctial point in relation to their sidereally defined zodiac. As in, in comparison to 0 Sidereal Aries, the equinoctial point was at 8, 10, 15 Aries. But this might have just been my massive assumption all along? If it is as I think it is, then I don't see why having several guesses in relation to the sidereal zodiac is so flawed, the basic principle behind it of trying to find the equinox and calculate from there is the same, it's just that the calculation is incorrect. With this in mind I don't see how it's all that different than taking an otherwise arbitrary fixed star such as Spica and using it as the basis of an ayanamsha - both are an attempt to define an otherwise fixed point and define their zodiac from it, even if there are competing calculations for how to do so.
Maybe I've been thinking of it obtusely though, I'm genuinely unsure now. I had always thought it was quite clear that the 8 degrees, 10 degrees etc. were in relation to a sidereal zodiac, almost the opposite to an ayanamsha, rather than subtracting from the tropical zodiac, instead adding to the sidereal zodiac if that makes sense. Am I wrong in that though?
