 In 1623 , Galileo published The Assayer — Il Saggiatore , which attacked theories based on Aristotle 's authority and promoted experimentation and the mathematical formulation of scientific ideas . The book was highly successful and even found support among the higher echelons of the Christian church . Following the success of The Assayer , Galileo published the Dialogue Concerning the Two Chief World Systems ( Dialogo sopra i due massimi sistemi del mondo ) in 1632 . Despite taking care to adhere to the Inquisition 's 1616 instructions , the claims in the book favouring Copernican theory and a non Geocentric model of the solar system led to Galileo being tried and banned on publication . Despite the publication ban , Galileo published his Discourses and Mathematical Demonstrations Relating to Two New Sciences ( Discorsi e Dimostrazioni Matematiche , intorno a due nuove scienze ) in 1638 in Holland , outside the jurisdiction of the Inquisition .
