[1] The Adoration of the Shepherds shows a nocturnal scene with Mary bending over the Child in prayer.
Joseph is standing over them holding a candle, but the main light source is coming from the crib.
The Child lies on a bed of hay that matches his Mother's halo, surrounded by winged cherubs.
In his work translating the bible and spreading his message, he hired Cranach to make illustrations and a candle featured in many of them.
This same scene in a simplified form was even featured in one of Cranach's woodcuts for Luther's Passional Christi und Antichristi: This painting was once in the collection of Richard von Kaufmann and was purchased by the museum from his estate in 1917.
