In his treatises Hero of Alexandria describes a range of devices for producing spectacles and generating wonder that have frequently been treated as marginal by historians of technology and science. In this paper I shall show that these devices and Hero’s emphasis on wonder-making are of central importance to the image that Hero presents of mechanics. Hero uses the concept of wonder to add an intellectual component to the utility of mechanics, to strengthen the epistemological claims of mechanics and to (...) relate mechanical expertise to divine cunning. He is thereby able to present mechanics as a form of knowledge which is epistemically on a par with philosophy, but which still maintains powerful practical consequence.Author Keywords: Hero of Alexandria; Wonder; Automata; Ancient Mechanics; Ancient Science.
