Black and white photograph. For Use at Will. Getting older and more evil as the years go by is Livia (Sian Phillips), Mother of Rome, and the power behind several thrones in "I, Claudius," the Masterpiece Theatre series seen Sunday evenings at 9 (ET)**. From the time she's first seen as a young woman (left) through middle and old age, she lusts for power at any price—including murder—in the Mobil-funded PBS series based on Robert Graves' best-sellers about a family whose business was ruling the world. **Please check local PBS listings.
