Season Greetings & Happy New Years!
Mythic Santa Concept
Santa + Sleipnir = creepy weirdness. The centaur alternative would be "Sleipnir", the 8-legged Viking horse who could ride the sky. This concept just produced creepy sketches (not shown here :) ). Winged horses might work, but didn't Santa have reindeer?
Deer + wings = "Peryton." Okay, Santa doesn't need wings if his reindeer have them. Thanks go out to Seabury Court Resident Mythologist Erin (a.k.a. daughter) for educating me that winged-deer actually have been classified already.
Sleigh or Chariot? Suitable vehicles for sky riding include chariots, as per Helios, Sun-driver. For starters I tried working with the chariot.
