Galileo replied to Castelli with a long letter laying out his position on the relation between science and Scripture. By 1615, with the controversy over the Earth's motion becoming more widespread and increasingly dangerous, Galileo revised this letter and greatly expanded it; this became the Letter to the Grand Duchess Christina .

In 1612 Galileo formally set out his views on this topic in his Discourse on Floating Bodies [note 7] and Delle Colombe swiftly replied with Discorso Apologetico [note 8] Galileo did not reply immediately, and indeed when his reply was published, it was over the name of his friend Benedetto Castelli.
