In arguing that there have been a few offerings that have been correctly the look after of specialists, Galileo used to be protecting a brand new kind of authority. Galileo then needed to conquer an important of all arguments: the argument that the Bible couldn't be flawed whilst it stated that the sunlight strikes. This used to be the most goal of his (undated) letter to the grand duchess Christina of Lorraine. it truly is worthy stressing that there's no facts that this letter used to be ever despatched to Christina, or that it was once truly meant for her. Galileo later wrote a letter to Ingoli which was once circulated generally among his supporters yet most likely by no means proven to Ingoli, and his ultimate letter on sunspots, although addressed to Welser, used to be on its manner throughout the press and into print earlier than Cesi prompt it'd be well mannered to ship Welser a duplicate. we all know that the letter to Christina was once initially addressed to another person, simply because we have now an early draft within which the meant recipient is a clergyman.
