Agnus Dei (Zurbarán)

Agnus Dei (Latin for Lamb of God) is an oil painting completed between 1635 and 1640 by the Spanish Baroque artist Francisco de Zurbarán. It is housed in the Prado Museum in Madrid, Spain.

The Lamb of God is an allusion to Christ's title as recorded in John's Gospel (John 1: 29) when John the Baptist describes Jesus as "The Lamb of God who takes away the sin of the World".The painting appears in Sarah Phelps' BBC Agatha Christie "quintet", And Then There Were None, The Witness for The Prosecution, Ordeal by Innocence, The ABC Murders, and The Pale Horse. Its repeated use is to symbolise the trussed nature of the guilty character who has put himself on the path to perdition.
