Portrait of Maria Mancini, Duchess of Bouillon, Jacob Ferdinand Voet
In the Rijksmuseum; English language page for the work here. There is a zoom icon under the image. The download link requires a free Rijksstudio account (worth signing up for to my mind). There is also a downloadable version on Wikimedia Commons.
Apparently, cautious historians have encouraged the Rijksmuseum to classify this beautiful portrait as “attributed to” Voet, but if the portrait is in Voet’s style by another hand, surely that hand is of a very good painter.
Despite the composition of the portrait and the style of the sitter’s garments — which are in keeping with the painting’s late 17th century origin — the immediacy and presence of the woman’s face and the wonderfully painterly application of color feel more like something out of the 19th century.
I love the soft edges of the hair as it fades into the background and falls across the woman’s shoulder in delicate wisps.
