The rulership of Aquarius by Uranus is not universally accepted and the reasons that led to this position are questionable. Modern astrologers have forsaken the tradition of double domicile for each planet (daytime and nocturnal, see attached image) to keep only the diurnal domicile. The diurnal domicile of the traditional planets outside luminaires are: Mercury-Gemini, Venus-Libra, Mars-Aries, Jupiter-Sagittarius and Saturn-Aquarius. With the arrival of Uranus, Saturn was dislodged from his diurnal domicile by Uranus, to be demoted to his nocturnal domicile Capricorn. But for what strange reasons did Neptune and Pluto not dislodge Mars and Jupiter who kept their diurnal domicile?
Maybe there was some semblance of logic. Keeping, as shown in the attached figure, the Ptolemaic succession Mercury/Venus/Mars/Jupiter/Saturn, Uranus would come to place in Aquarius and Neptune in Pisces. But then another problem arises for what strange reasons Pluto does not find itself in Aries? We start with a logic (the Ptolemaic order) but we do not push the logic to the end and we place Pluto in the Scorpion.
I have already proposed another way of proceeding (cf. articles published in the Astrologer, Nos. 199 and 200). It is about keeping day and night rulerships for every planet including the new planets. Thus Uranus, Neptune and Pluto must have a diurnal and nocturnal domicile. Traditional planets have to keep their traditional domiciles, because there are no good reasons to change them. Saturn must therefore remain in its diurnal domicile in Aquarius and nocturnal in Capricorn. The only possible logic, the one that respects both the traditional domicile and the Ptolemaic succession, is to attribute to Uranus the diurnal domicile of Capricorn and nocturnal of Aquarius, to Neptune the diurnal domicile of Pisces and nocturnal of the Sagittarius and Pluto the diurnal domicile of the Scorpion and nocturnal of the Aries. As a demonstration, we will take the theme of Rudolf Bing who have Ascendant, Sun and Moon in Capricorn and of Joris Huysmans who have Ascendant, Sun and Moon in Aquarius. Rudolf Bing is typically Uranian and Joris Huysmans typically Saturnian.
Rudolf Bing (1902-1997)- Ascendant, Sun and Moon -the legendary opera director remained more than twenty years at the head of the Metropolitan Opera of New York, creating for lyric representations new qualitative standards that will be generalized around the world and make this scene one of the obligatory passages for all the great singers.
Joris Huysmans (1848-1907),- Ascendant, Sun and Moon in Aquarius, writer, after having retired to several monasteries, he left Paris in 1899 to settle permanently in the small village of Ligugé, Near Poitiers in the Vienne, where he was built a mansion near the Benedictine abbey Saint-Martin. There he shares the daily life of the monks and prepares to become an oblate. After publishing a hagiography devoted to the mystical Christian Holy Lydwine of Schiedam (1901), Huysmans recounts his experience of monastic life in the Oblate (1903).
Of course this is not evidence, but I have investigated all the cases I have found presenting this configuration in the Astrodatabank database which includes about 50 000 cases. 7 cases for ASC/moon/Sun in Capricorn and 6 cases for ASC/moon/Sun Aquarius and for these cases all the dominant Capricorn are typical Uranian and all the dominant Aquarius are typical Saturnian.
