Original Format: photograph: negative
Description: After his condemnation by the Church, Galileo, though under house arrest, devoted himself to what would later be hailed as his greatest scientific work. He drew together in a systematic way his studies of dynamics, from which a whole new science of mechanics would grow. The last of his works to be published during his lifetime, the book was issued in Leiden and widely disseminated. It contained no mention of the Copernican system.
