Olmec, Mixtec, Toltec and Aztec all feared the feathered snake god, Quetzalcoatl. He was handed down to the Mayans as Kukulkán. He slithers each equinox down his pyramid at Chichen Itza and becomes ramrod straight at the proper hour. This could be him, but it's not. To gaze upon his true visage would turn you to a toadstool, so I've substituted an Incan icon of unknown origin. You're welcome.
