Risposta di Gio: Alfonso Borelli ... alle considerazioni fatte sopra alcuni luoghi del suo libro della forza della percossa del R.P.F. Stefano di gl'Angeli ..
A 1668 polemical reply in Italian, printed in Messina without a named publisher, by mathematician Giovanni Alfonso Borelli against Stefano degli Angeli's objections to his work on the force of percussion, aimed at natural philosophers and mathematicians. The pictures are plain geometric diagrams of a pendulum-like cone, a right-triangle lever setup and a rotating cone on a pivot, plus a woodcut initial showing a figure wrestling a man on the ground; a designer could draw on their clean line-drawn schematics and the expressive historiated letter.
