This drawing is a preparatory study of the same size and in the reverse direction for an etching by the artist that is signed with his monogram. A similar ox skull appears in a "vanitas" still life in a painting by Rosa of 1650, "Democritus in Meditation", in the Statens Museum for Kunst in Copenhagen, and in a print after the painting dated 1662.
