"Sarpi was a friend and benefactor of Galileo. He first acquainted his friend with the reports from the Netherlands about devices for seeing faraway (telescopes) and facilitated Galileo's offer of an eight-powered spyglass to the Venetian government (and the reward) in 1609. Galileo and Sarpi discussed and corresponded about various other subjects, including magnets, the tides, and the law of falling bodies." (Source: Website Galileo Galilei Project)."
