Calileo Galilei was the foremost scientist of his day. Though he never left Italy, his inventions and discovereis were heralded around the world. His telescopes allowed him to reveal the heavens and enforce the astounding argument that the earth moves around the sun. For this belief, he was brought before the Holy Office of the Inquisition, accused of heresy, and forced to spend his last years under house arrest. Galileo's oldest child was thirteen when he placed her in a convent near him in Florence, where she took the most appropriate name of Suor Maria Celeste. Her support was her father's greatest source of strength. Dramatically recolors the personality and accomplishment of a mythic figure whose seventeenth-century clash with Catholic doctrine continues to define the schism between science and religion. Moving between Galileo's public life and Maria Celeste's sequestered world.
