This picture derives directly from Solimena's painting of the same subject, and identical dimensions, sold at Christie's, 13 Dec. 1996, lot 122.
The subject is taken from Judges IV, 4-9. Deborah, an Israelite prophetess and judge, summoned Barak and instructed him to take three thousand men to the river Kishon, where God would deliver Sisera and his army into his hands. Barak agreed to go on condition that she accompany him, and the Canaanites were routed. Sisera escaped but was murdered by Jaal soon afterwards.
