Galileo’s book Two New Sciences is the culmination of a long line of mathematical investigations of motion, extending over 3 centuries up to Galileo’s unification of mathematics and physics.

Picture in Galileo's Discorsi (1638), p. 173. About The Law of Falling Bodies. It's very similar of Nicole Oresme's geometrical demontration of the Mean Speed Theorem
