The Day of Saint George passed back in April, and there are still images and articles about it going around on Facebook and cultural news websites. But one thing I have noticed since becoming a Hellenic Polytheist that probably most Greek Christians and other Christians around the world have not, is that he is copied from the ancient Greek Hero Bellerophon.
As you can see in the pictures above, Bellerophon from the 4th Century BCE and St. George from the Common Era, the two are basically identical. This was probably done by the emerging Christian church to get the Greeks to convert more easily to Christianity. Of course, when that didn't work, the church used force, but that's not really the topic of this post.
Bellerophon was sent to destroy the Chimera, a vicious fire breathing monster that ravaged the countryside of Lycia, an area in Asia Minor (keep in mind that dragons also breathe fire, which was the monster that St. George battled).
After being given the winged horse Pegasos by Athena, Bellerophon was able to attack the monster from the sky with His lance, with which He killed the monster, or in some versions, used the lance to shove a clump of led down its throat, which was melted by the monster's hot breath and killed it. Bellerophon was mainly the Patron Hero of Korinth, which was His birth City, although in His lifetime, it was actually called Ephyre.
