User blog comment:Ariel Saeba/Mythology and Character Origins in DxD/@comment-3151468-20160402061151

Well, I'm not very skilled at finding mythological reference to many of the issues already said in DxD.

but one thing I will not forget me is that Tiamat qualifies for the divine class, meaning that she is a goddess, she belongs to the Mesopotamian mythology, a creative goddess who was the mother of many gods with her husband Abzu / Apsu, which in time was designated as a dragon as it was tiamat although the latter its role as a queen dragon is more tremendous as it gave birth to a lot of dragons and monsters.

Here is the direct link above tiamat.

is not it crazy as a dragon is a god, I have noticed many gods in various mythologies dragons, with famous being Ryujin, Abzu and Quetzalcoatl

or others who are not as well known as Zirnitra, Xiuhcoatl, Fei-lian and others not even be.

I say this only to note those who read it.
