PEGASOS ,or Pegasus
was an immortal, winged horse which sprang forth from the neck of Medousa when she was beheaded by the hero Perseus. Pegasos was tamed by Bellerophon, a Korinthian hero, who rode him into battle against the fire-breathing Khimaira. Later, after the hero attempted to fly to heaven, the gods caused the horse to buck, throwing him back down to earth. Pegasos continued to wing its way to heaven where it took a place in the stables of Zeus.
The horse was also placed amongst the stars as a constellation, whose rising marked the arrival of the warmer weather of spring and seasonal rainstorms. As such he was often named thunderbolt-bearer of Zeus. In the constellation myths, Pegasos “Springing Forth” may have represented the blooming of spring whilst Khimaira “Frosty Air” or perhaps “winter-rising Capricorn” was the cold chill of winter.
