Everyone remembers that wig and the way it echoes the shape of those sumptuous skirts, which are draped over a support structure known as a guardainfante. She is the teenage queen immortalized in Diego Velázquez’s magisterial portrait Queen Mariana of Austria (circa 1652–53). Mariana lived from 1634 to 1696, and while she can’t be called a beauty, her self-presentation is elegant. Note how the red bows at her wrists set off the sterling severity of her black dress (the courturier Cristóbal Balenciaga certainly did). And the way her handkerchief cascades from her hand like a surrender, even as her coral-colored lips and cheeks form a row with the coral florets in her hairpiece, creating a horizontal line that brooks no dissent. The painting has come to the West Coast of America for the first time and will be shown among works by artists that the Habsburg court collected (among them, Nicolas Poussin, Guido Reni, and Peter Paul Rubens). The exhibition seeks to show how art helped shape Mariana’s approach to her political role. —Laura Jacobs
