This miniature was formerly attributed to Nicholas Hilliard and was said to be a portrait of Mary Tudor (1496–1533), sister of Henry VIII of England, queen of Louis XII of France, and subsequently duchess of Suffolk [see Ref. Reynolds and Baetjer 1996]. It may be compared in style to a miniature portrait of Anna Cernohorská of Boskovice in the Victoria and Albert Museum, London (no. P.168–1910), dated 1589 and attributed to Pieter Pietersz [published in Podává K. Svoboda, "Podobizna Anny Cernohorské z Boskovic v Londýne," Památky archeologické 35 (1926), pp. 464–67, pl. CLXVII].
