The moment
In 1616 the Inquisition's consultors judged the claim that the Sun stands still at the centre of the world to be heretical, Copernicus's book was suspended, and Cardinal Bellarmine warned Galileo not to hold or defend the idea. After Galileo published his Dialogue in 1632 he was summoned to Rome, and in June 1633 the Holy Office declared him 'vehemently suspected of heresy'. He knelt to abjure, the Dialogue was banned, and he spent the rest of his life under house arrest, from December 1633 at his villa at Arcetri, near Florence.
