Portrait of Galileo Galilei, Justus Sustermans

Nearly 400 years ago in April 1633 the Italian astronomer, mathematician and natural philosopher, Galileo Galilei was put on trial by the Roman Inquisition.

The main charge against him centred on his support for the Copernican theory, aka the belief that a mobile Earth orbited a stationary sun. The theory was thought to contradict the Bible and Galileo was placed on trial for heresy.

But what was Galileo’s real crime? Was science really defeated by religion, as legend would have it? These were some of the questions raised by Andrew Campbell from UCL Italian in his lecture Galileo: what was his crime?, organised as part of the UCL Festival of Culture.

I’ve always found the Galileo Affair fascinating and it’s often used as the leading example of the supposed battle between science and religion. Florence’s Galileo Museum proudly displays his mummified middle finger pointing towards the heavens – a definitive display of science triumphing over the Catholic Church.

When Galileo is mentioned today it’s often not in recognition of his scientific work but as the poster child for the war between religion and science. However, is it as simple as this – can you separate science and religion from the politics, and personalities, of the day?

To delve a little deeper into the whole affair Andrew provided a short run through of the events which led up to 1633.
