Forget Champion the Wonder Horse, Black Beauty or Roy Roger’s Trigger — PEGASUS is the real horse hero. The wings help.
Thereupon ZEUS blew up the horse’s nostrils, gave him a sugar lump dipped in Ambrosia and tamed him for pulling the best chariot when the King of the Gods wanted to do sky wheelies.
Eventually PEGASUS settled down with a wife and kids and spent the rest of his mortal life inspiring the MUSES.
Pegasus Fun Factoid: SF maestro Robert Heinlein once cast doubt upon the veracity of those famous wings, claiming that Pegasus’s wingspan ratio was all wrong. Apparently only a flying horse the size of a small dog is permitted by the laws of physics. Which can only mean one thing — ancient Greek Mythology was populated entirely by midgets.
