Thank you to Lynne for asking this question about Michael (Michel) Sittow’s portrait of a woman said to be Catherine of Aragon. The portrait of Katherine of Aragon painted by Michael Sittow on her marriage to Arthur shows Katherine with a halo around her headdress, and I read that the halo was painted on at a later date. I always thought that it was part of Katherine’s headdress, am I wrong?”

The painting by Michael Sittow, shown here, is beautiful. We don’t actually know for certain who it is and there has been controversy surrounding it in recent years because the Kunsthistorisches Museum in Vienna relabelled the portrait as being of Mary Tudor, sister of Henry VIII, based on “Henry VIII’s Favourite Sister? Michel Sittow’s Portrait of a Lady in Vienna”, an article by Paul G. Matthews. You can read more about this in Katherine of Aragon or Mary Tudor? – The Re-identification of Michel Sittow’s Portrait of a Young Woman by Nasim Tadghighi. For me, it makes more sense that it is Catherine.
