This bust-length portrait is of an unknown, 54-year-old man. Since the painting has no provenance it is not at present possible to identify him. The rather sketchy execution suggests that it is a copy. There is no known original, but on the evidence of the stylistic relationship to the work of the Amsterdam portraitist Cornelis van der Voort it is assumed that it is based on one of his paintings.1 The 1619 date on the present painting would have been copied from the prototype. Dendrochronology, which provides a likely date of execution in or after 1648, indicates that this copy was made some 30 years after the original.2 Gerdien Wuestman, 2007 See Bibliography and Rijksmuseum painting catalogues See Key to abbreviations and Acknowledgements This entry was published in J.
