Hello Tom, Deb, Magherita and everyone
I've intedend to post some considerations in this thread about the concern that Ptolemy explanation of temperaments raises, cause when Tom brought the subject to the fore, I myself already felt uncomfortable with it. The doubt raised by Morin is (partially) valid in my opinion, if we just follow the model Ptolemy presented us, Jupiter would be hot and dry. But after some thinking I believe that as any philosopher from his time, Ptolemy was trying to deviate from a simple mytical explanation to how astrology works (it was considered a science in his time after all, although the concept of science was very different during his age, and a degree of conflict was already present that would blow in Al-Biruni and Kepler's time). The theory of elements and the opposites like hot/cold, dry/wet is actually very old, probably originated from Babylon/Egypt and the chaldeans, and the first to touch the subject in a way that distance itself from myth was Tales (using the portuguese adaptation of names here), who said that all begins with water (any reminiscence to the Thema Mundi is probably not co-incidental). After him, his disciple Anaximenes already changed the theory to satisfy a concept of physis, in which this principle was actually air. Between them, there was Anaximaro, that talked about
?-peiron, as the absence of limits of quantitative and qualitative value explaining the principle of existence. Others would follow, stating it was actually fire, and so on...
So, there was disagreement on elements and their function, but I believe that the astrological model is very neat indeed, and there is justification in it for the planetary essential temperaments being traditionaly as they are. One thing we should accept first is, since the Sun is hot and dry, as we perceive fire like that, the Moon (and hence the night) can only be the opposite, cold and wet, dealing with the ocean and the winds. I did an scheme to make my point:
-----Saturn-----Jupiter---Mars---Sun----Venus---Mercury--Moon
--cold-----------hot--------hot---<hot>----hot------hot-------cold--
-----dry---------dry--------dry-----dry------wet-----wet------<wet>
Capricorn------Sagitarius--Aries----Leo---Libra----Gemini--Cancer
The arrows represent how the qualities spread, heat from the Sun in the center, and moisture from the Moon at the end. It's interesting to observe that in this scheme, all signs under the rays of the Sun show their diurnal quality. As the Moon is the essential nocturnal planet, reigning only when he sets, it is her nocturnal (and only) domicile that appears. For Saturn, as he is at the extreme opposite, far from the Sun's influence, as the Moon, it is also his nocturnal domicile which appears. This scheme is very interesting as it shows a hypothesis for the construction of domiciles. It shows as well how Mercury can relate to the concept of children and brothers, being nearer the sphere of the Moon and being touched by the Sun's it creates in Gemini an analogy for brothers as presented by Al-Biruni in a lot from one of his books (imho). Also is shown how the material genesis is processed on the inferior sphere, where the Moon reigns (being the other side of the Sun) through the casting of light onto darkness and uniting the principle of moisture to that of heat. I should point that ice is probably not a cold and moist thing, it's cold and dry, hence, the absence of light shows that water's moisture becomes dry (falling under Saturn alongside) as this concept is important to understand the point of how heat produces life/animation possible through moisture. Now, I will present the same scheme in a reversed way to make another point:
Moon-----Mercury----Venus------Sun----Mars----Jupiter---Saturn
--cold---------hot---------hot----<hot>---hot------hot----cold----
<wet>---wet----------wet---------dry------dry------dry----dry----
Cancer-----Gemini------Libra------Leo-----Aries---Sagitarius--Capricorn
When you reverse the chaldaic order of speed of the planets, it's clear which star opposes to which by principle, there is an in-built symmetry. Mercury opposes Jupiter, Venus opposes Mars, and the Moon (genesis) opposes Saturn (decay). Now, each other domicile a planet may have just reverses the quality of the first in the following scheme:
Saturn >
cold/dry Capricorn shifts to
wet/hot Aquarius
Jupiter >
hot/dry Sagitarius shifts to
wet/cold Pisces
Mars >
hot/dry Aries shifts to
cold/wet Scorpio
Sun > only diurnal
Venus >
hot/wet Libra shifts to
cold/dry Taurus
Mercury >
hot/wet Gemini shifts to
cold/dry Virgo
Moon > only nocturnal
The principle each of the planets had at day becomes the exact opposite at night. Now, although this scheme could explain the essential temperament of 5 of the 7 planets, Jupiter and Mercury still would pose a problem. At first I was ready to say that was because of the changeable nature of Mercury, but then, I acknoledged there were other factors at play in this. We would suppose that the planets essential meaning is the form/enviroment they should have in order to perform it's best. Each domicile represents this philosophy to a certain extent, but there is also distance and interplay of elements, the inner philoshophy in which they simbolically operate to our eyes and the influence of other bodies near them, alongside the qualities of another place where the planet is supposedly very strong, and that is exaltation. So let's look at how is the sum of temperaments from a planet's domicile with that of his exaltation:
Saturn - hot/wet + cold/dry + hot/wet
Jupiter - cold/wet + cold/wet + hot/dryMars - hot/dry + cold/wet + cold/dry
Sun - hot/dry + hot/dry
Venus - hot/wet + cold/dry + cold/wet
Mercury - hot/wet + cold/dry + cold/dry
Moon - cold/wet + cold/dry
Above I've highlited Saturn, Mars, Venus, Jupiter and the Moon because here they all could pose a problem. First the malefics: Saturn would have to be hot/wet and Mars cold/dry according to this. But are we not told that the malefics receive their domiciles because essentially they are too extreme in their qualities? So in the case of the malefics, hot/wet and cold/dry are places where they behave better cause there their extreme heat, coldness, and dryness are somewhat mitigated. In the case of Mars, where you see cold/wet, you should see hot/dry, and of Saturn, where you see hot/wet you should see cold/dry. Now, I think that this scheme also reveals a little more about the why to some Mars behaves better in his nocturnal domicile of Scorpio than his "natural" one of Aries and why Saturn is better in his diurnal one of Aquarius than his "natural" one of Capricorn. In Scorpio Mars is less dry and in Aquarius Saturn is less cold.
About Venus, I should point that she is the planet alongside Mercury that have been most questioned as to which is her true nature in the history of astrology. Some say she is hot/wet and others say cold/wet. I do think that all the inferior planets tend more to coldness than to heat essentially (hence they are always near the Sun ^_^), but I'm not to assertive on this. Venus is moderate cold following this scheme although in a diurnal chart she would be (obviously) hotter.
Now, just to close this, some comments on the remaining planets. Jupiter appears here as leaning more to cold and wet than to hot and wet. Still, no source ever considered it cold, they said it was moderate hot. Also, the scheme taking exaltation into account already crumbles in the case of Mars, that if received the reversing treatment like did to Saturn (cold means hot and wet means dry) we would fail at the final result. Still, it's not a 2 + 2 = 4 type of calculation. But at the very least, showing some value to it, the diurnal domiciles of the planets are perfectly arranged in this (revealing a truth about the domiciles, rather than to the planetary natures). Also, we should not be too strict, the principle of water + fire gives air, and Jupiter is indeed a lord of rains, so his moderation exists still even if it has too much moisture here opposed to his dryness in the first scheme, making it... moderate after all.
About the Moon, I think it is downright scary how perfectly this scheme describes her. Although the Sun gets two hot/dry, the Moon is cold/wet in Cancer and cold/dry in Taurus. There is a face of the Moon that is always turned to us, and the Earth is, after all in agreement to this, a body of water, so cold/wet. As the ancients
sensed/knew the Moon had a side always turned to us, they concluded that another side, a cold/dry one, never receiving sunlight to our eyes, in fact existed (her exaltation, that also could relate to how it's her far-side covering the Sun in a eclipse).
