Greek mythology records the legend of the birth of Pegasus, when Poerxiusi cut off Medusa's head. In mythology, Poerxiusi tried to clean up Medusa, the gorgon. Everything in Medusa's eyes would turn to stone, so Poerxiusi blocked Medusa's sight with a shield (this shield was given by Athena). And took the opportunity to cut off her head. Just as blood gushed from the neck, a winged white flying horse jumped out.
This is the myth of the birth of Pegasus.
