The Sun through the Decans
Using modern-day rulerships
Sun in 0-9 degrees Aries (first decan, ruled by Mars): extremely childish. They are the most driven of the Aries and possess a certain pure enthusiasm about them that is rather endearing.
Sun in 10-19 degrees Aries (second decan, co-ruled by Mars and the sun): the most self-centered of the Aries. Pretentious and charismatic but ultimately insecure and full of love. They really have no idea who they are to be honest.
Sun in 20-29 degrees Aries (third decan, co-ruled by Mars and Jupiter): the kindest Aries, also the shyest. Can be a bit outspoken, but tend to be less impulsive. They are made calmer by Sagittarius’s detachment.
Sun in 0-9 degrees Taurus (first decan, ruled by Venus): completely stable. They reject grandeur and prefer security, but they can be extremely driven and hardworking. The strong, silent type, but they are still very stubborn.
Sun in 10-19 degrees Taurus (second decan, co-ruled by Venus and Mercury): organized and intuitive. They are difficult to read and have a certain attractive quality about them. This is the most spontaneous Taurus.
Sun in 20-29 degrees Taurus (third decan, co-ruled by Venus and Saturn): they are very stoic. They are the most melancholic Taurus. They are strong-willed and quite controlling, and Capricorn’s influence can make them easily depressed, but also romantic.
Sun in 0-9 degrees Gemini (first decan, ruled by Mercury): strong mind with incredible adaptibility. They are fiercely charming and can be manipulative. They are also quite restless and often overly-intellectual. They, like their sister sign, like being right.
Sun in 10-19 degrees Gemini (second decan, co-ruled by Mercury and Venus): the stereotypical flirtatious Gemini. They are outgoing and loving, but they tend to toy with people’s feelings and are rarely honest. This is the Gemini who will make you fall in love with them for fun.
Sun in 20-29 degrees Gemini (third decan, ro-culed by Mercury and Uranus): quirky, verging on manic pixie dream girl territory. Detached and magnetic. The most honest and straightforward Gemini, but also the hardest to understand.
Sun in 0-9 degrees Cancer (first decan, ruled by the moon): deeply emotional. These are the most dramatic Cancers, as well as the most self-centered. They are both manipulative and easily-manipulated. They are, however, very caring, and they rarely do things out of malice, unlike other Cancers.
Sun in 10-19 degrees Cancer (second decan, co-ruled by the moon and Pluto): destructive and possessive, but also powerful and passionate. They are wonderful friends and massively emotional. Their emotions completely rule them, which is sometimes good and sometimes horrific.
Sun in 20-29 degrees Cancer (third decan, co-ruled by the moon and Neptune): with added mutable influence, this Cancer is hard to understand. They trust their emotions and intuition completely, but they are very easily influenced, so they often change things about themselves.
Sun in 0-9 degrees Leo (first decan, ruled by the sun): incredibly loving, but they do love themselves most of all. There is an intense need for praise and attention, and everything they do is about them.
Sun in 10-19 degrees Leo (second decan, co-ruled by the sun and Jupiter): I would argue that this is the most naturally powerful Leo as they combine their inherent charisma with the good luck of Jupiter. Ambitious and intellectual.
Sun in 20-29 degrees of Leo (third decan, co-ruled by the sun and Mars): this, however, is certainly the most driven Leo, perhaps even diabolically so. They are unable to see other people’s points of view.
Sun in 0-9 degrees Virgo (first decan, ruled by Mercury): as much as people may think that Virgos are self-critical, the double-Virgo is massively egotistical and narcissistic. They can be wonderful friends but they believe that they know best all the time.
Sun in 10-19 degrees Virgo (second decan, co-ruled by Mercury and Saturn): the kindest Virgos, as they combine the duty of Virgo with the devotion of Capricorn. This Virgo is intelligent and hardworking, but they may be emotionally repressed.
Sun in 20-29 degrees Virgo (third decan, co-ruled by Mercury and Venus): the ultimate charmers of the zodiac. They are ethereal and beautiful, and something about them makes them seem godlike. They are almost universally liked but are fairly private.
Sun in 0-9 degrees Libra (first decan, ruled by Venus): contrary to what some people may say, the pure Libra is quite selfish. They do everything in balance, and that means carving out time for themselves. They are also dramatically idealistic and romantic.
Sun in 10-19 degrees Libra (second decan, co-ruled by Venus and Uranus): this Libra is very independent. They are more likely to be drawn toward typical Libra-like humanitarian careers than the other Libras. They are the least romantic.
Sun in 20-29 degrees Libra (third decan, co-ruled by Venus and Mercury): this is the least-balanced Libra. What may be mistaken for Scorpionic influence really comes from the wild nature of Gemini, who makes this Libra unpredictable and dominating.
Sun in 0-9 degrees Scorpio (first decan, ruled by Pluto): they can be a bit nutty. They are the typical extreme Scorpios who want to be mysterious, enigmatic, and cool, but who are really overrun with feelings of loneliness.
Sun in 10-19 degrees Scorpio (second decan, co-ruled by Pluto and Neptune): this Scorpio is nicer and more outgoing than other Scorpios. They are caring and attentive but dislike being told what to do.
Sun in 20-29 degrees Scorpio (third decan, co-ruled by Pluto and the moon): although this Scorpio is probably the most prone to extremes, they are also the most caring. They can always see right from wrong.
Sun in 0-9 degrees Sagittarius (first decan, ruled by Jupiter): this is the true Sagittarius intellectual. They appreciate both truth and harmony and are not easily rattled. Their morals are strong, but they can be quite irresponsible.
Sun in 10-19 degrees Sagittarius (second decan, co-ruled by Jupiter and Mars): a more athletic Sagittarius. The “boy next door” Sagittarius probably has his sun in the second decan, as this Sagittarius is ambitious and adventurous, but not as intellectual as the other decans. Still, they are kind.
Sun in 20-29 degrees Sagittarius (third decan, co-ruled by Jupiter and the sun): the crazier Sagittarius tends to be born here. They are prideful, powerful, and passionate, and very attractive.
Sun in 0-9 degrees Capricorn (first decan, ruled by Saturn): a graveness of spirit lies with the first decan Capricorn. They are not necessarily ambitious, but they do hate failure. This Capricorn is cold and logical, but they have tremendous discipline.
Sun in 10-19 degrees Capricorn (second decan, co-ruled by Saturn and Venus): the most social and outgoing Capricorn, and also the least likely to express their love because they have the most of it. Saturn is naturally restrictive, and with Venus, that means that love is made a mountain to climb.
Sun in 20-29 degrees Capricorn (third decan, co-ruled by Saturn and Mercury): this is the luckiest Capricorn because things tend to come naturally to them. They are intelligent and quick-witted, and the pain of Saturn is felt less thanks to Mercury’s erratic personality.
Sun in 0-9 degrees Aquarius (first decan, ruled by Uranus): loyal and affectionate, and definitely the most consistent of the Aquarius decans. They are talented and intellectual, but they listen exclusively to themselves and border occasionally on narcissism.
Sun in 10-19 degrees Aquarius (second decan, co-ruled by Uranus and Mercury): this is the most fun Aquarius. Aquarius is co-ruled naturally by Saturn, and Mercury, as it does with the third decan Capricorn, makes the second decan Aquarius lively and intelligent.
Sun in 20-29 degrees Aquarius (third decan, co-ruled by Uranus and Venus): of the Aquarius decans, the third is the kindest. They have deeply-ingrained morals and value dependability. They tend to be optimistic and fair in nature, if a bit detached.
Sun in 0-9 degrees Pisces (first decan, ruled by Neptune): the most Neptunian of the Pisces. Emotionally intense and completely detached to everything, this Pisces floats through life with exhaustion, hoping that eventually they’ll find the proper shore. Life is possibly an endless quest for something that will never come.
Sun in 10-19 degrees Pisces (second decan, co-ruled by Neptune and the moon): this is the romantic Pisces. Giving and maternal, they would do anyone for the ones they love. I would argue that they are the most strong-willed and least manipulative of the Pisces.
Sun in 20-29 degrees Pisces (third decan, co-ruled by Neptune and Pluto): the psychic Pisces. Although some may assume that the late-born Pisces is Martian due to its neighbor Aries, it is really due to their Scorpionic influence. The most practical Pisces.
