The Air Triplicity is represented by the sanguine temperament, exhibiting active circulation, good complexion, genial nature, cheerful anticipation, good fellowship and general dexterity.
Air signs are intellectual and communicative. They are concerned with the things of the mind and function best in the mental level. Without them no reasonable planning is possible, no one would be able to think, let alone communicate ideas to other people. There would be no speech, no memory, no knowledge and no ability to criticize the excesses of other elements. Like fire and water, air relies upon earth for practical support.
The airy signs (Gemini, Libra, and Aquarius) are said to represent the relative or connective conditions both within and without the body. They express as active, scientific and industrial. They have a tendency toward illnesses arising from exhaustion or over-exertion.
HOUSES: The 3rd (relatives, neighbors), 7th (partners, 1-to-1 relationships), & 11th (social & mental relationships) houses are naturally ruled by Air signs and are considered the Houses of Relationships or the Relative Houses. Many planets in these houses describes someone who needs others.

In Medical Astrology and Astro-Meteorology the Air element is of the humour Sanguine, being hot and moist.
GEMINI: Mutable Air
Gemini: The house that has Gemini on the cusp (beginning) shows the place in your life where communications and a constant information flow are important to you. Do you have Gemini on the cusp of the 8th House (sex)? Then you will never be “turned on” by anyone who is quiet. Stimulating, light, and “fun” conversation, though, should do the trick, before, after, and even during. But remember that Gemini is Mutable, adaptable, and easily influenced. This interpretation is modified by the sign and house placement of Mercury (ruling planet of Gemini) in your horoscope, as well as its aspects. For instance, if Gemini is on the 8th cusp and Mercury is in the sign of Capricorn, then the conversation will have to be about a serious subject.
LIBRA: Cardinal Air
Libra: Libra rules beauty, art, charm, and the “social graces”. Gemini is raw information. With Libra, this is taken one step further. Libra is Partnership. We don’t just have people bumping into each other and exchanging information like two ships in the night.
While Gemini tends to witty, interesting information, Cardinal Libra gravitates towards beautiful communication. Libra is also the sign of Fairness and Justice. Its placement in your horoscope (along with the placement of its ruling planet, Venus) shows the place in your life where these qualities are most visible and most important to you. The house with Libra on the cusp (beginning) is also the place where the need for beauty is most noticeable.
AQUARIUS: Fixed Air
Aquarius: Notice how this builds upon the previous sign: Gemini is brothers and sisters (local level), Libra is marriage and partnership (friendship circle is expanding), and Aquarius is friendship and brother/sisterhood which are universal and all-encompassing. Aquarius is always trying to stretch the boundaries, if not break them. In the Zodiac, it comes right after the earth sign Capricorn, which rules organization, form, and limitations. Aquarius rips the boundaries and breaks the old forms so that it can bring in something new and startling. It is like Prometheus, defying Zeus to bring the gift of fire to humanity. Like Prometheus, many of them suffer for it.
In the horoscope, the house with Aquarius on the cusp (beginning) as well as the house that contains Uranus, its ruling planet, shows the places in your life where you can be at your most original and independent. If there is any genius in you, these are the places where it will tend to come out. Be careful though. These are also the places where you will be the most Rebellious, where you can shock people. Fixed Aquarius and Uranus tend to defy any established authority (except their own, of course). They have an open, direct, “in-your-face” quality that is unmistakable, but can get you into a lot of trouble.
CLASSICAL RULERSHIPS (traditional astrology)
This set of signs is ruled by Saturn by day and Mercury by night. The air triplicity relates to the sanguine humour which finds its seat in the blood. It is considered warm and moist in temperament.
The Libra triplicity is diurnal, comprising Gemini, Libra and Aquarius. Saturn takes precedence during the day, because it both rules Aquarius and is exalted in Libra, while Mercury, ruler of Gemini takes precedence at night. Venus, the ruler of Libra is dismissed because it is a nocturnal planet and so needs to be substituted for a diurnal one. The options are Jupiter or the Sun. Since the Sun is essentially debilitated in two of the three signs that make up this triplicity, Jupiter is the natural choice.

Capricorn trigon – Venus, Moon, Mars
Most early astrologers used all three planets, rotating their priority by day and night, but many later ones, including Lilly, chose to use only the principal rulers. Perhaps they rejected the convoluted logic that lay behind the definition of sect, or perhaps they were confused by Ptolemy who only mentions two rulers for the Aries and Capricorn triplicities, yet mentions three rulers for the others.
