The Philadelphia Museum of Art honours Irish-born American painter and sculptor Sean Scully with a retrospective. The exhibition 'The Shape of Ideas' offers a comprehensive overview of the last fifty years of his artistic creation, including paintings as well as works on paper. It explores the artist's distinctive stripes and reflects his bold experimentation with scale and composition. The works on display – from the intimate to the monumental – reveal Scully's tireless dedication to the expressive power of painting.
