At the time when I first put this view forward, I was unable to offer any concrete proof of the existence of such a standard on Greek soil before the introduction of coined money, although the literary evidence was of the strongest kind. Since then I have been enabled to obtain some data of considerable importance. I have already (Chap. II.) described the rings and spirals of gold and silver found at Mycenae, and shewn that they were not improbably made on a standard of 135 grs. We have thus found some definite evidence of the existence of a gold and possibly a silver standard, corresponding to the standard used for both metals in after ages under the name of the Euboic or Attic. It may of course be argued that though found on Greek soil, they are not really Greek in origin. For instance there may be certain indications of Egyptian art and influence in these pre-historic remains, such as the frieze discovered in the Palace at Tiryns of alabaster inlaid with blue glass which according to Lepsius and Helbig[290] is the mock _lapis lazuli_ which the Egyptians were so fond of making in imitation of the rare and costly real stone which had to be brought from Tartary. Granting then for the sake of argument that the Homeric _Talent_ was a standard introduced into Greece from Egypt at a very early period, it by no means follows that this standard has had a scientific origin. The Greeks it will be noticed found it necessary in taking over this standard to equate it to their primitive barter system. If then the process of human development is such that the Greeks, who above all people shewed the most extraordinary power of acquiring civilization, found it necessary even when presented with a ready made standard for metallic currency, to bring it into harmony with their immemorial system of appraising values by means of the cow, there is certainly a strong presumption that the people from whom they derived that metallic standard had not themselves obtained it by any mathematical process.
