Galileo, title page from Dialogo...sopra i due Massimi Sistemi del Mondo, Tolemaico, e Copernicano (Dialogue concerning the Two Chief World Systems, the Ptolemaic and the Copernican), Florence, 1632
Galileo's intent with this book was to present the two world systems, the Ptolemaic and the Copernican, in easy to understand, dialogue form. His optimism concerning the acceptance of the Copernican system was misplaced; one year later he was brought to trial and forced to abjure his ideas.
