Professor Thomas DaCosta Kaufmann has confirmed the painting's authenticity on the basis of photographs and dated it most likely to the end of Spranger's stay at Rome or possibly to his first years in Central Europe. He compares the painting and its execution in brownish monochrome with the painting "St. Luke Painting the Virgin" in the collections of the Alte Pinakothek, Munich (inv.-no. 14357).
