In a new catalogue raisonné, scholar Christof Metzger argues that The Painter’s Father (1497), a painting in the collection of London’s National Gallery, is in fact an authentic work by Albrecht Dürer.

The Painter’s Father, gifted to King Charles I of England in 1636, has long been thought to be a copy made decades after Dürer’s death in 1528, based on a lost original. But in the new publication Albrecht Dürer: The Complete Paintings, Metzger—a Dürer expert and curator of German art at Vienna’s Albertina Museum—contends that the face is “preserved so well that the painting’s formerly outstanding quality is still perceptible.” He told the Art Newspaper that the London work stands apart from at least seven known early copies of the portrait of Dürer’s father for its “experienced brushwork and masterful glazing technique.”
