That would be St. Michael the Archangel.

The cherub and the moon were later human additions. One of the wonderful things about the image is that it is a composite image. The underlying image of Mary floats above the coarse fabric of the tilma like a photographic emulsion, and science cannot determine how the image was formed -- i.e., no brush strokes or the like. On the other hand, the stars, the crown, the cherub and other details were added over the years by the Aztecs and Spanish-Americans.

I'm still looking for a site that describes the infrared studies made of the image.
