In the Scandaglio, Galileo’s friends tried to refute Grassi’s Astronomical Balance. This obscure and mysterious work appeared under the name of the brother of the better-known Francesco Stelluti, one of the founders of the Academy of the Lynx and friend of Galileo and Prince Cesi. It was published in a small town near Cesi’s estate in Acquasparta. At this time, Cesi was helping Galileo prepare The Assayer, his definitive response to Grassi, which contains large sections of material copied directly from the Scandaglio.
