Libra is ruled by the Planet Venus. In ancient Roman mythology, Venus (and her Greek equivalent, Aphrodite) was the Goddess of Love, Beauty, and Pleasure. She represented joy, happiness, and appreciation of beautiful things. On the negative side, her appreciation for sweets and luxury could result in overindulgence, and she could be materialistic. Venus rules both Libra and Taurus. Libra is the masculine, or day, aspect of Venus; Taurus is the feminine, or night. Both Signs have a great appreciation for beauty, but while Taurus appreciates the beauty of things, Libra is more interested in the beauty of other people. Librans are happiest when they're in a relationship. They are seductive and attractive, and their cultural awareness and talkative nature make them help them shine in the social situations they so enjoy. Because of their social nature, they can be vain or overly dependent on others' approval. Many people born under Libra have strong artistic tendencies and a refined sense of style, but they can also become lazy and apathetic if bored. They are usually controlled and rational, but at times they may be self-indulgent.

The Element associated with Libra is Air. Air Signs are intellectual: they tend to respond to the world through intellect, rather than physical action, practicality, or emotion. Libra's intellectual orientation to the world around them makes them skilled at communication and abstract reasoning, and their intelligence combines with their interest in other people to become an intellectual exploration of the people around them. Because their efforts are mentally rather than emotionally motivated, Librans tend to be very judicial; they are good at diplomacy and compromise. Because they are generally reluctant to face confrontation, people born under Libra learn to be persuasive, courteous, and adaptable. But this may also make them seem cold and unemotional or manipulative. They are team workers, skilled at cooperative action, but they can also be self-doubting. Open minded and always polite, they have a strong sense of loyalty because of their ability to put themselves into other people's shoes.

Librans love to debate but not to quarrel; a fine distinction that is nonetheless very important to people born under this Sign. They are kind and considerate, and they rarely display anger. Instead they may employ subtle means of getting even when their strong sense of fairness and legality or refined sensitivities are violated.

In their leisure time, Librans tend to have less energy that other Signs, and they have a definite lazy streak, preferring to read and go out with friends. Exercise generally appeals to them only if it allows socializing at the same time, but some have a particular affinity for activities that let them get out in nature, such as hiking and horseback riding. In love relationships, Libra is playful and romantic.

Libra rules the kidneys and lower back. People born under Libra may be more susceptible to back pain or strain than people of other Signs. Libra's colors are ivory, pink, and light blue; these three colors are harmonious in all their combinations, and they all appear in the sunset sky that Libra represents.

The great strength of the Libra-born is in their drive for peace and harmony. Their ability to obtain balance and cooperation from a disparate group is unparalleled. Their skill at seeing all sides of a situation makes them one of the most just characters of the Zodiac.
