Pannochieschi, head of the University of Pisa, defended Columbe, widening the debate over floating bodies and exemplifying the Aristotelian physicists’ reaction to Galileo’s use of Archimedean methods. In response, Galileo published a 2d ed. of his Discourse on Floating Bodies within the same year (1612, not on display), in which he answered Pannochieschi’s criticisms.
