The author discusses the archaeological evidence for an Aegean Minoan maritime colonization of southeastern Iberia. The primary causal factor for this was the development of the alloying technology of arsenical copper. The alloy’s hardness and castability made the woodworking tools of the saw, bow drill, and lathe possible. These tools set the stage for the invention of the first efficiently produced planked wooden ships with keels in the Aegean that set out on voyages of exploration early in the 4th Millennia B.C. in search of the prestige metals of gold and silver resulting in the Los Millares culture in southeastern Spain.
