The Danubians were Andonites, farmers and herders who had entered Europe through the Balkan peninsula and were moving slowly northward by way of the Danube valley. They made pottery and tilled the land, preferring to live in the valleys. [1] Greeks imported Danubians as slaves. [2] The most northerly settlement of the Danubians was at Liege in Belgium. [3] The Danubians became mother worshipers as the result of the work of the missionaries from Crete. [4]
