ANGLO-DUTCH SCHOOL, CIRCA 1665 PORTRAIT OF A YOUNG WOMAN Miniature with transformations Oil on copper and 16 painted micas In its oval embossed leather case (accidents to the micas, wear to the case). Anglo-Dutch school, ca 1665, Portait of woman, transformable miniature, oil on copper and 16 painted micas, embossed leather case, damage to the micas, wear to the case 8,60 x 7 CM - 3,4 x 2,8 IN. A rare "miniature with transformations", with 16 transparent mica plates that can be superimposed to dress the portrait in different costumes (for a masked ball, in a black lace mantilla, in an evening coat), to disguise it (as a nun, a beguine, a peasant girl with a fichu, a sultana) or to disguise it as a man with moustaches and a feathered hat or a tsar's hat. This portrait could evoke Henriette of England, Duchess of Orléans, known as Madame (Exeter, 1644- Château de St Cloud, 1670), daughter of King Charles I of England and Henriette of France, themselves painted on several occasions for miniatures with transformations. A very similar portrait with minor variations in hairstyle, and also 16 painted mica, is in the Colonial Williamsburg Museum in Virginia (the model unidentified). Very few of these sets, executed for a very high-ranking clientele in the second half of the 17th century, are known today. Two others were sold by Tajan: a young brown woman in a pink dress and 11 micas on 24 April 2020 (no. 36), and a young woman identified on the inside as Henriette de France and 22 micas on 20 June 2001 (no. 2).
