The Great Red Dragon

"A great sign was seen in heaven; a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars. And being with child, she cried out in labor and in pain to give birth.
And another sign was seen in heaven; behold, a great red dragon, with seven heads and ten horns, and seven diadems upon his heads.
His tail dragged a third of the stars from heaven and threw them to the earth; and the dragon stood before the woman who was ready to give birth, to devour her child as soon as it was born..."
