Libra
general summary for a strong Libra placement
What the tradition reads
Libra is the cardinal sign of air, the sign that opens the season of autumn as the Sun crosses the equinox into it, and the tradition reads that timing as central to the sign's meaning: light and dark stand briefly equal, and Libra is the sign asked to hold two things level rather than choose between them. Its ruling planet is Venus, and where Venus in Taurus is read as appetite and pleasure, in Libra she is read as relation, what is fair, what pleases both parties, the tact that keeps a room comfortable. Libra is the only sign of the twelve pictured as an object rather than a creature or a figure, the scales themselves, and the tradition takes the symbol seriously: a strong Libra placement is read as someone who instinctively weighs, compares and balances, sometimes to the point of finding a decision difficult to reach at all, because seeing both sides clearly is exactly the gift and exactly the cost. Libra governs the seventh house in the natural wheel, the house of partnership, marriage and the dealings one has with another as an equal, and the sign's shadow is read as an aversion to conflict that avoids the disagreement a partnership actually needs.
The story
Libra is a late addition to the zodiac. For most of antiquity the Babylonians and then the Greeks read this stretch of sky as the claws, chelae, of the neighbouring scorpion, reaching out ahead of the creature's body; the Romans were the ones who separated the claws into their own sign and gave them the shape of a balance instead, and the change stuck because it matched something the Romans already valued in this part of the sky. The Sun crosses into Libra at the autumn equinox, when day and night stand equal for a moment before the dark begins to win, and Roman writers took the balanced scale as the natural picture for a balanced season. The scales are also the attribute of Astraea, the virgin goddess of justice, said to have lived among mortals during a golden age, teaching honesty and fair dealing, and to have withdrawn to the sky as the world grew corrupt, becoming, in most tellings, the constellation Virgo beside her scales rather than the scales themselves. The image endures for the same reason in both goddess and sign: a balance is the one instrument that cannot be made to favour a side until someone has already tampered with it, which is exactly the claim of impartiality both Astraea and the autumn sign named for her scales were asked to carry.
