Mary Tudor/Catherine of Aragon, Michael Sittow, circa 1514

This portrait of an unknown noblewoman from the early 16th century was identified as a young catherine of aragon, c. 1500-1505, by max jakob friedländer in 1915, based on comparisons with other paintings by sittow. (max j. Friedländer, “gemäldegalerie. Ein neu erworbenes madonnenbild im kaiser-friedrich-museum”, amtliche berichte aus den königlichen kunstammlungen, 36, 9 (1915), pp. 1-4. ) this was subsequently challenged by matthews (paul g. Matthews, “henry viii’s favourite sister? michel sittow’s portrait of a lady in vienna”, jahrbuch der kunsthistorischen museums wien 10 (2008), pp. 140-149. ), who argued it was mary tudor, henry viii's sister, painted in 1514. The website of the kunsthistorisches museum (where the portrait is located) describes this painting as both "portrait of a princess (infanta catharine of aragon (1485-1536), queen of england?)" (https://www. Khm. At/objektdb/detail/2441) and "mary rose tudor (1496-1533), sister of henry viii of england". In the physical gallery the painting is described as mary rose tudor. (http://www.
