Just look at this amazing artwork from ancient Mesopotamia, of the hero/king/god Ninurta fighting a seven-headed dragon! The above image is a clearer rendering of the 5000-year-old carved-shell original piece below.
I found this on fellow blogger Wayne Ferrebee‘s site ferrebeekeeper: Reflections Concerning Art, Nature, and the Affairs of Humankind (also some gardening anecdotes). (His blog looks amazing, so I immediately followed him, and you should too!)
Check out his short post to get the whole story of Ninurta and the dragon here: Sumerian Seven Headed Dragon.
As I’ve mentioned before, my novel series takes place as my protagonists travel across many ancient cultures, and one of them is based on ancient Mesopotamia, which had me trying to find some of the earliest depictions of dragons. I hope you enjoy! Stay creative!
