A Historical Memoir of Science, Faith, and Love

Inspired by her long fascination with Galileo, and by the remarkable surviving letters of his daughter, which she has translated into English for the first time, Dava Sobel has written a book of great originality and power, a biography unlike any ever written on the man Albert Einstein called “the father of modern physics – indeed of modern science altogether.”

Galileo Galilei (1564-1642) was the foremost scientist of his day. Though he never left italy, his birthplace, his inventions and discoveries were heralded around the world. His telescopes allowed him to reveal a new reality in the heavens and to publicly propound the astounding argument that the Earth actually moves around the Sun. For this belief he was brought before the Holy Office of the Inquisition, accused of heresy, and threatened with torture. In contrast, his daughter Virginia, became a cloistered nun. Born in 1600, she was thirteen when Galileo placed her in a convent near him in Florence, where she took the most appropriate name of Suor Maria Celeste. Galileo later said of her that she had an “exquisite mind,” and her intelligence and loving support proved to be her father’s greatest source of strength through his most difficult years.

“I had two daughters who were nuns and whom I loved dearly, but the eldest in particular, who was a woman of exquisite mind, singular goodness, and most tenderly attached to me.” – Galileo Galilei (July 28, 1634)

Galileo’s Daughter brings Galileo to life as never before—boldly compelled to explain the truths he discovered, human in his frailties and faith, devoted to family and, especially, to his daughter. Her presence graces his life now as it did then. Their voices, and those of others who touched their lives, echo down the centuries through letters and writings, which Sobel masterfully weaves into her narrative, building toward the crescendo of history’s most dramatic collision between science and religion. In the process, she illuminates an entire era, when the flamboyant Medici grand dukes became Galileo’s patrons, when the bubonic plague wreaked its terrible devastation and prayer was the most effective medicine, when the Thirty Years’ War tipped fortunes across Europe, and when one man fought, through his trial and betrayal by his former friend, Pope Urban VIII, to reconcile the Heaven he revered as a good Catholic with the heavens he revealed through his telescope. An unforgettable story, Galileo’s Daughter is a stunning achievement.
