In 1633, the Roman Inquisition condemned Galileo as a suspected heretic for defending Copernicus's hypothesis of the earth's motion and denying the scientific authority of Scripture. This book draws upon Maurice A. Finocchiaro's earlier works, especially The Galileo Affair: A Documentary History (1989), to provide a brief, new documentary history of Galileo's trial that is simultaneously the most user-friendly and inclusive available.
