Very few portraits of Johan Ernst van Nassau Siegen, who died young as a general in the Uskok War fighting to defend the Venetian Republic, are known: one bust-length likeness, in which he wears a flat collar and different armour, attributed to the workshop of Ravesteyn, is in the Rijksmuseum, Amsterdam,1
while another, three-quarter-length portrait, in which he wears a more comparable ruff and sash, is recorded by the RKD at auction in Munich, Rudolf Neumeister, 17 February 1995, lot 657, as (after?) Jan van Ravesteyn. The present portrait follows the type used by Mierevelt in his so-called Orange Series of portraits, including those of William, Philip William, Maurice, and Frederick Henry of Orange, now in Museum Prinsenhof in Delft.
We are grateful to Anita Jansen for endorsing the attribution to Mierevelt on the basis of first-hand inspection of the painting.
