Automata Old and New

This paper surveys the history and mechanics of self-moving figures, tracing accounts from ancient literary and philosophical sources through Hellenistic engineering to modern showpieces. It describes mythic and early mechanical devices, examines technical principles such as siphons, pneumatics, weights, valves, and steam, and presents case studies including animal and human automata and coin-operated machines. The account blends cultural context—temple wonders and public entertainment—with practical explanations and reproductions of notable designs, showing how ingenious mechanisms have been applied to spectacle, ritual, and technological demonstration.
