What “Bestial Signs” Meant in Traditional Astrology
In older astrological writing, bestial was a classification for zodiac signs pictured as four-legged animals. The word comes from “beast,” and the label described the sign’s symbolic form—not a person’s character or behavior.
That imagery helped astrologers sort the zodiac into categories. Signs shown as people or human figures could be described as human; signs shown as animals could be called bestial. The categories treated a sign’s picture as a clue to its supposed qualities.
From Animal Form to “Instinct”
The association with instinct followed an old contrast between animal and human nature: animals were imagined as acting from appetite and impulse, while humans were associated with reason. In that symbolic framework, a bestial sign could therefore be linked with instinct rather than deliberation.
This was a system of interpretation, not a claim established by biology or psychology. Its logic is visible in the label itself: the image of a four-legged creature supplied the metaphor, and the metaphor supplied the meaning. That small act of classification shows how traditional astrology turned pictures in the zodiac into a vocabulary for describing human tendencies.
