The work delves into the principles of buoyancy and the reasons behind the floating and sinking of solid bodies in water, offering a detailed analysis and challenging Aristotelian concepts about gravity and density. The opening of this discourse sets the stage for a rigorous examination of the scientific theories behind the natation (floating) and submersion of bodies in water. Galileo introduces the subject by addressing Don Cosimo II and discusses his previous astronomical observations, before delving into a debate with learned men about the nature of gravity and buoyancy. He posits that the weight of a solid relative to the density of water determines its behavior in water, suggesting that figure or shape does not inherently affect a body's ability to float or sink. Through definitions and axioms, he outlines his intention to provide a logical and mathematical foundation for the observations, framing his discourse as a more effective means of argumentation compared to verbal disputes.
