You are Capricorn if born between 22nd December and 20th January. If you were born on the first or last date of this sign, then you may feel an affinity with the characteristics of the previous sign (Sagittarius) or the following sign (Aquarius). This may be to do with your Moon sign, or your actual Sun sign if the affinity is with the previous sign. (See Precession of the Equinoxes).
Capricorn is a Negative, Cardinal Earth sign, so we have Negative Earth, being careful and cautious, coupled with Cardinal Earth, meaning that Capricornians look onwards and upwards in their attempts to gain security in the world. The Cardinal Earth of Capricorn is determined and responsible, and can have dual attributes. It can be the solid clay soil which sticks to boots, weighing down with responsibility and cares, or it can be the lofty mountain crags over which the mountain goat leaps with ease, dealing with problems in a systematic way, rather than being mired in tedium. All careworn Capricorns want to be that majestic, horned mountain goat at heart, living their solitary lives in airy splendour, but with hooves firmly anchored to the Earth by solid, ages-old, rock. The ancient symbol of Capricorn was the mythical Sea Goat, and, as Sagittarius was originally represented by the mythical Centaur, half man, half horse, so Capricorn the Sea Goat was half fish, half goat.
The Capricorn character
Capricorns are often in danger of becoming mired in responsibility, and can become old before their time. The planetary ruler of Capricorn, Saturn, imbues the Capricornian with a sense of grim determination to see things through, and Cardinal Earth means that they will stick at tasks, pursuing their goals to the bitter end. In general, the Capricorn person wants to feel safe and secure, and wishes to be the provider of safety and security for themselves and their family, and can be single-mindedly ambitious in achieving these aims. They are often serious characters, preferring to deal with tasks on their own, eschewing offers of outside help, and are also quite happy spending hours alone. They are often good problem-solvers, and a loyal, faithful partner and friend. The Capricornian also needs to beware of becoming too miserly in the interests of economy, and being too obsessive about sticking to their rules of punctuality and order. They can also be hoarders, clinging on to reminders of the past.
Capricorns are often grave in bearing, with a long, sometimes lined, face. They may suffer from skin problems, often having had acne when younger. They have dark or reddish hair, and walk with a purposeful gait, usually being fairly loose-limbed.
If you are Capricorn, then the above is just one aspect of your astrological make-up, as there are many other signs which will influence you, depending upon their position at the time of your birth. The most important influence comes from your Moon sign.
