The Historisch Museum Den Briel has turned up a portrait of William of Orange, which was painted by Michiel Janszn after his death (1584). van Mierevelt, probably in 1617. It was in the home of a private individual.
It is an oil on panel measuring 30 by 24.5 centimetres. William of Orange wears black armor with gilded decoration on the painting. A Dutch art dealer bought the work a few years ago from a private collection in Spain and sold it on to a Dutch collector in the Delft area.
The panel will be exhibited this summer at the exhibition Het Huis Oranje-Nassau in Brielle and at Voorne-Putten in the Historical Museum Den Briel. According to the museum, it has never been exhibited before.
