Gunner firing a cannon, 1561. The path of the projectile is shown according to Aristotelian physics. Since he believed that no body could undertake more than one motion at a time, the path had to consist of two separate motions in a straight line. From Problematum Astronomicorum by Daniele Santbech. (Basel, 1561).
