Known as pterippi (pteros in Greek means "winged" and hippos means horse). Pegasus is a pterippus, and a magnificent one at that. The symbolic meaning of the horse is pretty intense with themes of power and mobility. The horse alone also carries archetypal themes of unifying grounded stability (four feet on the ground) with higher ideals (from speed and mobility). This theme really comes to life when we add wings to the horse. The pterippus, or winged horse, is a symbol of aspiring to the greatest heights of accomplishment. These beasts embody the concept of harnessing magic in the material plane. That's right, altering the physical matter via nonphysical methods. These kinds of feats are accomplished by swallowing whole the reality of our physical presence and balancing that with our (mostly) nonphysical nature/essence.

That's heavy. To help grasp those implications, Pegasus offers great analogy because of the dichotomy it offers. Grounded by the stability of its body, yet in flight by the ephemeral power of its wings. High and low (mind and body). Pegasus (white in color) stands for clarity of mind, and how clean mental focus combined with stable footing can transform our lives in magical ways. There's scads more about Pegasus to chat about, but this page is on the meaning of wings, not Pegasus.
