this paper is the second part of our recent paper 'Historical and Epistemological Reflections on the Culture of machines around the renaissance: How science and technique Work' (Pisano & Bussotti 2014a). In the first paper-which discussed some aspects of the relations between science and technology from Antiquity to the Renaissance-we highlighted the differences between the Aristotelian/Euclidean tradition and the Archimedean tradition. We also pointed out the way in which the two traditions were perceived around the renaissance. the Archimedean tradition is connected with machines: its relationship with science and construction of machines should be made clear. it is enough to think that Archimedes mainly dealt with three machines: lever, pulley and screw (and a correlated principle of mechanical advantage). As underlined in the first part, our thesis is that many machines were constructed by people who ignored theory, even though, in other cases, the knowledge of the Archimedean tradition was a precious help in order to build machines. Hence, an a priori idea as to the relations between the Archimedean tradition and construction of machines cannot exist. in this second part we offer some examples of functioning machines constructed by people who ignored any physical theory, whereas, in other cases, the
