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.[citation needed] ./cache/en-wikipedia-org-3784.html ./txt/en-wikipedia-org-3784.txt
