automata since Antiquity: automata have often been related to the idea of creation, suggesting that man could build another being, though artificial, by means of his competence and knowledge, forcing or imitating natural laws. Human interest about automata however seems not to be constant along the centuries: we witness an increase in the number of studies, and quotations, mainly in periods in which big and rapid technological development is in action, while in technological stagnation periods, references inevitably decrease. This study covers the part of the automata history that ranges from the Antiquity to the Renaissance, due to the strong interdependence of design and content, recurring during the considered centuries, as it will be more widely discussed in 1.2.3. 1.1 Literature Review A main question must firstly be faced, related to the word used to refer to automata. The etymology of the term passes through the Latin automatus, transliteration of the Greek adjective αὐηφκαηνο, coming from the determinative adjective αὐηὸο (self) and the verbal adjective καηὸο (having in mind, acting) 1. It was at first used to refer to any event or human behaviour that was spontaneous, without external intervention; only later, during the Hellenism, its use was extended to those mechanical devices, which perform, after a user‘s input, a finite number of default actions, typically, but not necessarily in a periodic sequence. It follows that in classical literature we find the words automatus / αὐηφκαηνο (and derived) used in contexts where no automata are involved (Homer, Ilias, II 408; Hesiod, Works and Days, 102-105; Aristophanes, Acharnians 976; Petronius, Satyricon, L and CXL), and, on the other side, we have descriptions of automata, where the term is not present (Homer, Ilias, XVIII 468-473; Odyssey,
