>And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
>And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.

Only shows up in the Second Temple period, after the Babylonian captivity, after the rabbis adopted Babylonian paganism. Conspicuously seven headed with fire coming from each head.

Anyone got a deep dive on this? Is it supposed to represent the Dragon? Or maybe the Beast from the Sea? Books/documentaries appreciated
