"The Mysterious Goddess
Isis wears a veil, a symbol of the mysteries of life. Her right hand carries the torch of life-its three flames represent the past, present, and future. Her left hand holds the key of life. An ancient Egyptian goddess and an American President are an unlikely pairing. But it provides a powerful visual link between Hoover's childhood and his life's dedication to the welfare of others."
