GALILEO CASE The celebrated case of Galileo Galilei (1564-1642), Italian physicist and astronomer, whose conflict with ecclesiastical authorities has become part of world history. In 1616 he was brought before the Inquisition on the charge of ignoring the implications of the Copernican(heliocentric) theory, which seemed to contradict the biblical story of the stopping of the sun in the Book of Joshua.
