Moving over large stretches of country the nomad took a wider view of life. He touched on the confines of this settled land and that. He was used to the sight of strange faces. He had to scheme and treat for pasture with competing tribes. He knew more of minerals than the folk upon the plough lands because he went over mountain passes and into rocky places. He may have been a better metallurgist. Possibly bronze and much more probably iron smelting were nomadic discoveries. Some of the earliest implements of iron reduced from its ores have been found in Central Europe far away from the early civilizations.
