A symbol of the Philadelphia Museum of Art is once again looking radiant in bright shiny gold after a yearlong restoration. It’s the 13-foot-tall sculpture of the Roman goddess Diana in an archer’s pose, ready to fire her arrow. The work by American sculptor Augustus Saint-Gaudens originally crowned an early venue for New York’s Madison Square Garden, where it served as a weather vane starting in 1893. The museum acquired it in 1932. Museum officials said that 180 square feet of gold leaf was applied over the 700-pound work.
