Gustav II Adolf was the son of Carl IX Gustafsson Vasa and his second wife Christina, Duchess of Hollstein-Gottorp. He ascended the Swedish throne in 1611, married Eleonora, Margravine of Brandenburg, in 1620, and was killed near Lützen on 16 November 1632. Van Mierevelt’s lost portrait of Gustav II Adolf is known from a 1633 engraving by his son-in-law Willem Jacobsz Delff.2 The present painting is a rather mediocre copy of either Van Mierevelt’s portrait or Delff’s reproductive engraving. It differs from the engraving in that the decoration on the sash is summarily reproduced and the lace has been left out.
