In 1848, seven rebel artists banded together and founded the Pre-Raphaelite Brotherhood. Their goal? To veer away from the stifling conventions of the Victorian age, and bring back the detail and vibrancy of Quattrocento Italian work. Of the seven, the young Dante Gabriel Rossetti was the most celebrated. Rossetti wasn’t known for his technical mastery, but his work was heated and sensual, and his paintings of women bordered on the mythological. This is the first-ever solo exhibition of Rossetti’s portraits. Masterpieces include The Blue Silk Dress and Monna Vanna (on loan from the Tate). —E.C.
