Galileo Galilei
Galileo later discussed the question in his most famous work, Dialogue Concerning the Two Chief World Systems, published in 1632 by permission of the Inquisition. His scientific writing was usually in Latin for hundreds of scientists around Europe, but this was one of the books he wrote in Italian so thousands of Italians could read it. The book was in the form of conversations between three men. The man representing the Church's point of view was called 'Simplicio'.
