What did the Earliest Church Fathers teach about the Woman of Revelation 12?

This question is a rephrase of a different question asking if any early church fathers believed that Revelation 12:1-5 is about the Virgin Mary. It may be clearer and easier to find out *what they actually believed*, rather than look for a presumption. >And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars: And she being with child cried, travailing in birth, and pained to be delivered. Revelation 12:1-2 With these first two verses, we may easily dismiss the idea that the woman does refer to the Virgin Mary. It doesn't. The reason is because some teach that she did not experience pain in child birth. Can't have it both ways. If it is about the Virgin Mary, then she experienced pain. >To the woman he said, "I will greatly increase your labor pains; with pain you will give birth to children. You will want to control your husband, but he will dominate you." Gen 3:16 NET As well, as mentioned, at least so far I have not found any early church father teach that the verse is about Mary, the mother of Jesus Christ. There are suggestions about her virginity, but nothing about the Woman clothed with the sun is Mary. So, what did the earliest church fathers teach about Revelation 12 and the Woman?
