This appears to be one of a set of portraits of ‘court beauties’ two of which are in the Royal Collection (this one and CWLF 142, 402850) and two elsewhere (San Diego Museum of Art and formerly Mathiesen, Berlin). But which court? The costume is certainly Spanish in style and should probably be dated c. 1600, but such dress was also worn at courts in Italy and Flanders with close relations to Spain, such as Brussels, Genoa, Turin, Modena or Mantua. The artist is similarly difficult to place, though probably Flemish perhaps working at one of the foreign courts listed above. Frans Pourbus theYounger is an example of just such an artist working at this date, but the style here does not resemble his work.
