Final answer:
Dante Gabriel Rossetti continued the legacy of the Pre-Raphaelite Brotherhood by evolving their style from naturalistic medievalism to romantic symbolism, particularly through his depictions of women after the group had disbanded.
Step-by-step explanation:
Dante Gabriel Rossetti was a founding member of the Pre-Raphaelite Brotherhood (PRB), a group that sought to reform art by returning to the styles that existed before the artist Raphael. They focused on medieval themes and emphasized nature and romanticism. After the disbanding of the PRB in the late 19th century, Rossetti continued to influence the movement, albeit in a modified style. He concentrated on creating romanticized images of women, as seen in his work 'Proserpine', using models such as Jane Morris. These paintings retained the Pre-Raphaelites' characteristic lushness of detail and brilliant color but departed from the fine-grained naturalism showcased in the group's earlier works. Rossetti personified a link between the brotherhood's initial nature-inspired realism and its later medievalist romance, marking the movement's evolution from its realist roots to a more symbolic, aesthetic style.
Despite Rossetti's lesser commitment to the PRB's original tenets, his fusion of their early ideas with his distinct interpretation helped extend the legacy of the Pre-Raphaelites, maintaining their spirit of artistic and spiritual idealism in the face of industrialized England's more materialistic art forms. As such, Rossetti's work represents a continuation and transformation of the Pre-Raphaelite mission into the fin de siècle.
