The writing describes the arrival of Thetis at the workshop of the god Hephaistos where she fi nds him busy fi nishing a set of twenty wheeled tripods on which cauldrons have been mounted. The mobile cauldrons are to be placed around the walls of the gods’ banqueting hall and will be of assistance in serving the fare. Of particular interest is that these devices are self-controlling (l. 376, “αυτοματοι”, i. e. “automatic”).
