But you may never have heard of this one: A lamassu (or alad, or shedu or aladlammu) is a guardian deity from the area we now call Iraq. Different cultures depict them with slightly different iconography and with slightly different purpose, but perhaps the best known version is the one of the Assyrians, who put huge carvings of them at the entrances of their cities.
It is a silly little picture that takes itself entirely too seriously, but I was so pleased with the wings and background that I thought it was worth sharing. Unfortunately I couldn't manage to get the head/neck attachment right. I think if the beard were not a requirement I could work something out with the primary muscles of the neck, but with them obscured there's just not much I can do about it.
