The recent Munich catalogue (Munich 2013) lists this painting as a collaboration with Rottenhammer. It has previously always been attributed to Van Balen working after a drawing by Rottenhammer (Lemgo; Ertz; Werche) and I feel sure that this was correct. The faces of the figures are quintessential Van Balen.
Werche lists two copies: Dijon, Musee des Beaux-Arts, Inv. #CA 162 (canvas, 20.5 x 28.6) & Sotheby's London May 16, 1984, #56 (panel, 31 x 40.5).
