The results of a petrographic and geochemical study carried out on archeological grindstones allow to provide new constraints on protohistoric commercial exchanges over the Mediterranean area. Eleven grindstones, discovered in an archeological site located in Milazzo (Messina, Sicily) and dated from the Early Bronze Age, have been investigated by geochemical and petrographic techniques. The raw materials are mainly volcanic rocks characterized by calc-alkaline and K-alkaline affinities with volcanic arc geochemical signature. Only one sample, made of basalt belonging to the Na-alkaline series, shows an intraplate signature. The comparison with the available literature data for similar rocks allowed constraining the volcanic origin of the exploited lavas. While the intraplate-type raw material came from Mt. Etna Volcano (Sicily), the arc-type volcanic rocks are mostly trachyandesites, basaltic andesites, and one rhyolite. Although most of them come from the Aeolian Arc, a provenance of some samples from the Aegean Arc cannot be excluded. This last region could represent the most probable provenance area for the rhyolite sample. 相似文献

Catherine H. Zuckert 《Perspectives on Political Science》2018,47(1):27-37
Erica Benner and Leo Strauss have recently challenged the reigning consensus that, having concentrated on politics, Machiavelli was not a philosopher. Readers did not always consider Machiavelli's work to be unphilosophical; and whether a commentator considers Machiavelli to be a “philosopher” depends on his or her understanding of what a philosopher is. Neither Benner nor Strauss takes the activities and studies of professors of philosophy in universities today to be definitive. Instead, they look to an older tradition both describe as “Socratic.” Benner rests her argument primarily on Machiavelli's references to Xenophon, Plato, and Plutarch. Unfortunately, Machiavelli's references to the works of Xenophon and Plato do not include those that feature Socrates. Strauss points out the similarities between Socrates and Machiavelli's emphasis on the political and their appeal to the young, but he concludes that, although Machiavelli is a “political philosopher,” his use of philosophy to serve the desires of the demos means that he is not a “Socratic.” 相似文献
