In the first four months of 2017 JVDPPP examined a further 30 panel paintings, with seven more to be seen this week. This will bring the total to 81, with around 250 to go. As the investigations continue, so the clues (including a fingerprint!) mount up, and possible patterns begin to emerge. We would like to thank the curators, conservators and owners at the following locations for their considerable kindness and assistance: the Kunsthistorisches Museum, Vienna; Akademie der bildenden Künste, Vienna; Museum of Fine Arts, Budapest; The Courtauld Gallery, London; Rubenshuis, Antwerp; Museum Mayer Van den Bergh, Antwerp; Musei Civici Vicenza; Museo Civico Ala Ponzone, Cremona; Palazzo Rosso, Genoa; Bonnefanten Museum, Maastricht; Private collections, United Kingdom, Germany, France and Belgium.
Below is a detail from the recently examined Philip by Van Dyck in a private collection in Germany, previously known only through a black and white photograph in the 2004 Van Dyck – A Complete Catalogue of the Paintings (I. 65, as ‘whereabouts unknown). On the reverse we were delighted to discover a panel maker’s mark (that currently ascribed to Guilliam Aertssens, active 1612 to 1626 and possibly beyond) and the Antwerp brand of the Guild of Saint Luke.
