The title of the painting: Adoration of the Shepherds

The Adoration of the Shepherds can be considered a relief sculpture because it bears and combines essential symbols, and it depends on its surface. Here, Baciccio made very much use of the power of lighting and shadowing effects. In the drawing, the only source of light is exuding from the baby, illuminating the faces of the crowd around him and casting dark shadows of the shepherds.

This technique of creating pictures wherein light pierces darkness is dubbed as the Art of Nocturnal Light. In this art, the source of the light is something divine, artificial, natural, or has held figurative relations beyond its common role. The nocturnal light – which can be candlelight to add intimacy, fire to symbolize power, or moonlight for landscapes – is intended to enhance the drama of the spiritual sight. (www.getty.edu)
