The Angel Departing from the Family of Tobias, Rembrandt van Rijn, 1641
Tobias wanted to give half of the riches he had brought along to his travelling companion, who then revealed that he was the Archangel Raphael, sent by God, whereupon everybody bowed down in shock. When they looked up, the angel was gone. Rembrandt derived the idea of showing only the legs of the departing angel from a 16th-century woodcut by Maarten van Heemskerk.
