A fascinating biography that gives an intimate look at the life of Galileo through the 124 letters written by his eldest daughter, Virginia, published in translation for the first time from the Italian. Virginia was one of Galileo's three children born out of wedlock. Together with her depressive younger sister, she was placed in the Convent of San Matteo near Galileo's Florence home at the age of 13, where she took the name Suor Maria Celeste, in tribute to her father's work. Galileo recognized in Virginia an "exquisite mind," and she, in turn recognized the depth of her father's faith in Catholicism and proved to be an unwavering source of loyalty, support, comfort, and strength for him when he was brought to trial before the Holy Office of the Inquisition in 1633.
