Gog and Magog. (first acceptable image)

"The names are mentioned together in Ezekiel chapter 38, where Gog is an individual and Magog is his land."

But the inspiration doesn't came from this... but from an old french cartoon named "Les mondes engloutis" ( The sunken worlds ). I think some episodes are influenced by Lovecraft's work, like this particular episode named "Gog and Magog": "In this country, people sing to endure the horrible sound of the wind.” A white phoenix convinces Arkana that Arkadia is behind a door closed by the vibration of the two branches of a tuning fork. Above the tuning fork floats a black stone... the fall of which would stop this tuning fork and open this door. But behind this door are the terrible armies of Gog and Magog...
