This is a good facsimile copy of a drawing formerly in the collection of Prof. Van Regteren Altena, Amsterdam. Another copy of the Amsterdam drawing is in the British Royal Collection, Windsor Castle.
The Prado copy has a distinct flavor of Agostino Carracci about it, and the copyist could have been from within the Carracci circle.
