If this was a mistake, it pre-dated Ptolemy. Deb cited an earlier horoscope (archaeological find) with this system. It is also in Dorotheus. There is little doubt that Dorotheus lived in the first century CE but it is unclear how much of his work was modified by his Muslim translator/editor, however.Graham F wrote:Hello

But I don't think my initial question, to which I kept trying to return, was really so difficult to understand: I was asking about the relationship of the classical rulership scheme to the tropical year, i.e. to the solstice/equinox (antiscial/contra-antiscial) axis), not about names of constellations which have been applied to the 30? sections of the ecliptic.

...once more : I asked if anyone, apart from Fagan, had floated the idea that they could logically be expected to match, to be organised around the same axis.
It turns out Ptolemy did, unambiguously if only implicitly, in the chapter on the "Houses of the Planets" :(the zenith of the annual cycle, the most northern point, is of course what is conventionally called the tropic of Capricorn, the "most northern part" being the segments to each side of it, before and after). If one of you who knows Ptolemy well had pointed this chapter out, adding perhaps that "it must be a mistake or an oversight, as elsewhere he is clear that the VP is at 0? Aries, and in various places [e.g. chapter on triplicities] it's clear that he considers Aries to be ruled by Mars, etc", I'd have had my answer straight away: end of story.)of the twelve signs the most northern, which are closer than the others to our zenith and therefore most productive of heat and of warmth are Cancer and Leo
Moreover if the Cancer-Leo axis was a mistake, we might question why none of the astrologers who followed Ptolemy (that I know of, anyway) sought to correct it.
By "most northern point" do you mean the tropic of Cancer? Today it passes through southern Egypt. It was probably discovered/invented by Eratosthenes who lived in Egypt in the third century BCE.
If you are arguing that a Gemini-Cancer symmetrical sign arrangement around the summer solstice point makes more sense than a Cancer-Leo arrangement, it has to be said that Ptolemy, wearing his weather and geography hats, had additional considerations. He itemizes them in Book 2 of Tetrabiblos. There is more than one kind of symmetry needing correlation, plus some sort of "deposit of faith" from Aristotelian proto-science, ancient Greek cultural astronomy, Babylonian astrology, and ambient astrological conventions that would either have to be worked in or discarded for good reason.I've tried to make it clear that I was asking (myself, first, but you also) a question not about constellation-derived sign-names, but about the relation between the classical rulership scheme and the annual tropical cycle, as structured by the solstices and equinoxes.
.........
I feel that the conventional rulership scheme (in terms of its solar and lunar halves) is not symbolically appropriate in terms of its placement with regard to the solstice axis.
.....
OK, but this is kind of a misreading of Ptolemy as a scientist. He didn't see astrology as occult, but as a systematic type of analysis and prediction. His contemporary Valens is full of exasperation at the woo-woo writings of some of his predecessors (whom he names, like Petosiris,) whereas Ptolemy simply strips out most of the metaphysics.I feel there's an analogy between the mirror pattern of the antiscia and the mirror pattern of the rulerships scheme, if you don't see an analogy there, fair enough, analogy is rather subjective by nature. But I agree with Michael that "analogy is the foundation of all the occult sciences".
I'm not questioning the position of the sun at or around the summer solstice, nor refuting some kind of "mad dogs and Englishmen" argument about ancient people who were intimately acquainted with their desert environment. I do suggest that climate was one of Ptolemy's considerations. He says so in Book 2. Further, if you need two signs surrounding 0 degrees Cancer, Associating the hot drying sun with the hotter drier month makes sense.....
...
Waybread, I agree that if you think the the most useful analogy to draw with the rulership scheme is not with the cycle of the Sun's maximum and minimum light, but with the temperature cycle in the Egyptian desert, then yes, Leo may well be better started 30? after the summer solstice, as it is conventionally. But even in Egypt the Sun is higher, and burns you more quickly, at the summer solstice than five or six weeks later.

Another consideration might be hours of daylight during the astrological months. This site gives sunrise and sunset data at Alexandria, Egypt, http://www.timeanddate.com/sun/egypt/alexandria?month=1 for anyone who would like to work this out for astrological months.
One other thing that Ptolemy talks about is the known world in relation to triplicities and planetary rulers. An astronomical/astrological basis for dividing up territory was known to the Israelites, ancient Egyptians, Babylonians and Greeks.
Somehow this all had to work out, and perhaps Ptolemy has satisfied that he had made the best job of a difficult challenge.
