Tackling Galileo as astronomer, engineer, and author, David Wootton places him at the center of Renaissance culture. He traces Galileo through his early rebellious years; the beginnings of his scientific career constructing a “new physics”; his move to Florence seeking money, status, and greater freedom to attack intellectual orthodoxies; his trial for heresy and narrow escape from torture; and his house arrest and physical (though not intellectual) decline. Wootton reveals much that is new—from Galileo’s premature Copernicanism to a previously unrecognized illegitimate daughter—and, controversially, rejects the long-established orthodoxy which holds that Galileo was a good Catholic.
