A number of Nativity scenes depict Jesus as the main source of light. This is from a vision of St. Bridget
, who writes that he shone brighter than the sun. In this painting, there are also two lesser sources of light, the angel still shining in the sky over the fields where the shepherds watched their sheep, and even more dimly, the fire of the shepherds. The result is a stark contrast between the things of earth and those of heaven.
