Latin commerce assumed a different direction. Rarely as we have opportunity of instituting comparisons between the Romans and the Etruscans as regards the reception of Hellenic elements, the cases in which such comparisons can be instituted exhibit the two nations as completely independent of each other. This is most clearly apparent in the case of the alphabet. The Greek alphabet brought to the Etruscans from the Chalcidico-Doric colonies in Sicily or Campania varies not immaterially from that which the Latins derived from the same quarter, so that, although both peoples have drawn from the same source, they have done so at different times and different places. The same phenomenon appears in particular words: the Roman Pollux and the Tuscan Pultuke are independent corruptions of the Greek Polydeukes; the Tuscan Utuze or Uthuze is formed from Odysseus, the Roman Ulixes is an exact reproduction of the form of the name usual in Sicily; in like manner the Tuscan Aivas corresponds to the old Greek form of this name, the Roman Aiax to a secondary form that was probably also Sicilian; the Roman Aperta or Apello and the Samnite Appellun have sprung from the Doric Apellon, the Tuscan Apulu from Apollon. Thus the language and writing of Latium indicate that the direction of Latin commerce was exclusively towards the Cumaeans and Siceliots. Every other trace which has survived from so remote an age leads to the same conclusion: such as, the coin of Posidonia found in Latium; the purchase of grain, when a failure of the harvest occurred in Rome, from the Volscians, Cumaeans, and Siceliots (and, as was natural, from the Etruscans as well); above all, the relations subsisting between the Latin and Sicilian monetary systems. As the local Dorico-Chalcidian designation of silver coin --nomos--, and the Sicilian measure --eimina--, were transferred with the same meaning to Latium as -nummus- and -hemina-, so conversely the Italian designations of weight, -libra-, -triens-, -quadrans-, -sextans-, -uncia-, which arose in Latium for the measurement of the copper which was used by weight instead of money, had found their way into the common speech of Sicily in the third century of the city under the corrupt and hybrid forms, --litra--, --trias--, --tetras--, --exas--, --ougkia--. Indeed, among all the Greek systems of weights and moneys, the Sicilian alone was brought into a determinate relation to the Italian copper-system; not only was the value of silver set down conventionally and perhaps legally as two hundred and fifty times that of copper, but the equivalent on this computation of a Sicilian pound of copper (1/120th of the Attic talent, 2/3 of the Roman pound) was in very early times struck, especially at Syracuse, as a silver coin (--litra argurion--, i.e. "copper-pound in silver"). Accordingly it cannot be doubted that Italian bars of copper circulated also in Sicily instead of money; and this exactly
