Astrologically associated with Libra and the Seventh House
Pegasus types are theorists who aim to achieve in reality what they conceive with the mind. They are perfectionists who strive to produce order from what they regard as the chaos around them. They detest disorder and ugliness and have a particular flair for creating beautiful surroundings in which to live. They can be highly original and possibly eccentric. They are curious and open-minded but will require convincing evidence to back up ideas. They show exceptional organizational ability. Although they are among the least outgoing of the types they are very concerned with promoting social harmony. Their ability to be objective and impartial makes them popular as fair-minded arbiters of disputes. They are extremely independent and can seem emotionally distant.
