In this image of Mary as a young mother cradling the baby Jesus, Mary's shape is reminiscent of the crescent moon. She is painted with cool colors, and her halo is a full moon. Baby Jesus, on the other hand, is painted in warm colors, with a sun halo.
The connection of Mary with the moon is nothing new. There are many icons oforiginal Mary standing on a crescent moon. The moon symbolizes femininity and fertility. We often refer to our menstrual cycle as a "moon cycle," and in some Red Tent societies, women go to "moon lodges" when their cycle begins.
Similarly, one symbol of Jesus is the rising sun. Jesus is "the light of the world." The use of the sun to symbolize God is certainly not new. In fact, some believe the ancient Church chose December 25th as the day to celebrate the birth of Jesus because it was the day of a Roman celebration that was widespread at the time: Dies Natalis Solis Invicti, or The Birthday of the Unconquered Sun. The Winter Solstice is a time in which many religions celebrate the birth of the sun. This is the day Isis gives birth to the sun god Horus. The Wiccan horned god is reborn from the Goddess every Yule, an act symbolic of the return of the sun on solstice. Alban Arthurian ("The Light of Arthur") is a celebration of the birth of King Arthur (not a sun god to be sure, but interesting nonetheless).
