The pegasus is a winged monster, a horse with an eagle’s wings grafted to its shoulders. Its association with the Muses of Greek myth makes it a popular charge with poets. As an heraldic charge, it dates from at least 1544, in the arms of Cavalere or Cavalier [Dennys 157].
The pegasus does not seem to have a default posture, so the posture must be blazoned. By Society rulings, a rampant pegasus (as shown in the illustration) may also be blazoned “segreant”, like the dragon, griffin, and other four-legged monsters with wings. For related charges, see horse.
