Towering over the reflecting pool at the new Barnes Foundation building on the Benjamin Franklin Parkway sits The Barnes Totem a 40-foot bead-blasted steel sculpture. Don’t try to figure out exactly what it is. That’s not the point. Instead, contemporary artist Ellsworth Kelly wants you to stop, look and feel what you feel. This is the first public work by Kelly installed in Philadelphia, and it’s the last in as series of totems that the 88-year-old master of American art has been creating since the 1970s.
