About this source

What it is

Published in Boston in 1870, this book was compiled mainly from Galileo's correspondence and that of his eldest daughter, Sister Maria Celeste, a nun at a Franciscan convent in Arcetri. It draws on the collected works of Galileo edited in the mid-1800s. The copy here is a scanned library book.

Why it matters

This compilation offers a more personal, domestic picture of Galileo through his family letters, rather than focusing only on his scientific discoveries or his trial. It also highlights the life of his daughter, who remained close to him from within her convent.

Look closer

  • Why might letters between family members reveal a different side of Galileo than his scientific writings?
  • What might be lost or changed when a compiler selects and arranges someone else's letters into a book?
  • What does the involvement of his daughter, a nun, suggest about Galileo's family and its relationship with the Church?
