Burne-Jones’s daughter Margaret modeled for this painting. The Latin title refers to the Vestal Virgins of Rome, who tended the perpetual fire on the altar of the goddess Vesta. Begun before Margaret’s marriage in 1888, the painting aligns her with these chaste women, suggesting her innocence and purity. "Flamma Vestalis" remained in England until 1922, when it was purchased by New York–based collector Grenville Winthrop and given a distinctly American frame. This style of frame was designed in the 1880s by eminent architect Stanford White. The design was known as a “U-shaped grille frame” because of the shape of its ornament. Evoking gilded lattice or lace, the grille catches and refracts light so that the painting and frame seem to shimmer. "Flamma Vestalis" is unique in this gallery: it is a British painting in a famously American frame, evidence of the collector’s preference rather than that of the artist.
