Der interessante Hinweis auf Kearney bezieht sich auf dessen Publikation "The Indian Ocean in World History" , dort zum Kapitel "The Earliest Leadership in Indian Ocean Trade". Das angedeutete Zitat verdient eine etwas nähere Betrachtung, weil interessant. Kearney führt folgendes aus: "Sumer’s trade and creativity spreads to the Atlantic and to the Pacific The trade enjoyed by the Sumerians extended to both east and west, following the principal water routes in each direction. Four major new civi- lizations resulted, two to the east (the Indus Valley and Chinese) and two to the west (Egyptian and Iberian – see page 13). Sumerian traders appeared in both Egypt and the Indus Valley, while the trade to China and Spain went through intermediaries... The (land) trade stimulus to Chinese society Sumer’s vitality resulting from its trade routes across the Indian Ocean allowed it also to establish a major land route across Central Asia to China. The Sumerian trade contact helped to stimulate China in the second half of the third millennium BC into creating its own civilization as well. While this development came via overland trade, the Chinese society stirred into life would later come to play a major role in the Indian Ocean trade, and thus world history. This was the period of the legendary ﬁrst dynasty of China, the Xia, based in the Huang Ho (Yellow River) Valley of northern China. The region was called Chung-Kuo (‘Central Land’), which is still the name used by Chinese for their country. This area was the part of China that land trade from Sumer would naturally encounter ﬁrst, by the route across Central Asia and Sinkiang." Leider gibt er dazu keine Basisliteratur an, auf die er sich bezieht. Am Ende des Kapitels werden lediglich allgemeine Literaturvorschläge gemacht, die überdies keinen Bezug zu diesen sehr weitgehenden Aussagen möglich machen. Findet sich das sonst irgendwo in Literaturdiskussionen wieder, ggf. mit archäologischen Nachweisen dieser Kontakte?
