The only evidence to show that Demeter was worshipped at Metapontum is that a female head on certain of her coins is accompanied by the legend Σωτηρία. It has been inferred that this is an epithet of Demeter, but this is most unlikely, for in that case we should expect Σὼτειρα, as on the coins of Hipponium, Syracuse, Agrigentum, Corcyra, Cyzicus, and Apamea, not Σωτηρία, as the adjective. Thus we always find Ζεὺς Σωτήρ, not Σωτήριος: cf. Σώτειρα Εὐνομία, Pind. Ol. IX. 16, Σώτειρα Τύχα, Ol. XII. 2, Σώτειρα Θέμις, Ol. VIII. 21. Σωτηρία is rather Safety (Lat. Salus), who, as my friend Mr J. G. Frazer points out to me, was worshipped at Patrae and Aegeum, two of the chief towns of Achaea (Pausan. VII. 21. 7; VII. 24. 3). We also find such names of divinities as Ὑγιεία, Ὁμόνοια and Νίκα on the coins of Metapontum. As Metapontum was an Achaean colony, it is likely that Salus was worshipped there also. Besides it was to Apollo, and not to Demeter, that they dedicated their golden ear as a harvest thank-offering. Θέρος is the ear cut from the stalk after the ancient way of reaping, cf. θέρη σταχύων, Plut.
