Jan Porcellis (Ghent 1583/5-1632 Zoeterwoude)

We are grateful to Dr Jeroen Giltaij of Museum Boymans van Beuningen, Rotterdam and Dr Jan Kelch formerly of the Staatliche Museen, Berlin for confirming the attribution on the basis of a photograph (written communication, 4 and 19 March 2008, respectively). Dr Kelch points out that this is probably a late work by Porcellis dating from the late 1620s. He compares it to Shipping in an estuary by stormy weather in Museum Boymans van Beuningen, Rotterdam (inv. no. 1675).
