We shall be able to judge better if we look at the actions of Nordics in later times. At the downfall of the Roman empire it was not unusual for quite small bands of Nordics to become masters of even large territories; some of the Norsemen made themselves, single-handed, kings of the cities in South Russia. Later Rollo, with but a handful of men, became Duke of Normandy and defied the power of the Carolingian monarch; later still small groups of Normans conquered Sicily, and set up their rule in many places in the Mediterranean region. Lastly, how often have Englishmen, sometimes quite alone, gained great influence in large communities of aliens, and been in a position to make themselves kings had they not preferred to annex the community to the British Empire? Thus has much of the Empire been built up. But by far the best parallel is the case of the first Rajah of Sarawak. When such events have taken place in historical times, even in our own day, we cannot consider it as impossible that wandering Nordic heroes from the Danube basin, accompanied perhaps by a faithful henchman, should have found it possible to establish themselves as kings over the trading cities of Mycenean Greece. But let us glance for a moment at these trading cities and their inhabitants. The original people of the Greek mainland, like the bulk of the present population, seem to have been of that eastern Alpine or Dinaric type, scarcely distinguishable from the bulk of the population of Asia Minor. These are tall dark people, with small but broad heads, which are very high and somewhat conical at the top, though sometimes the excessively flattened occiput gives the impression that the head has been sliced from the top of the forehead to the back of the neck. As far as one can judge from the available evidence, these were the only inhabitants of the bulk of the peninsula, until coastal settlements were made by the Cretans, some in the second Middle Minoan period, but most of them at the beginning of the Late Minoan.[362] The original inhabitants of Crete seem to have been typical members of the Mediterranean race, but during Early Minoan times we find a few broad-headed people arriving in the east of the island, and gradually spreading over the eastern half.[363] It has been taken for granted, quite naturally, that this broad-headed infusion came from Asia Minor, the population of which at that time must have been exclusively broad-headed. But about the time that these broad-heads appear in Crete we find evidence in the island of the development of the copper mines at Gournia,[364] and of the accumulation of gold ornaments, such as the treasure of Mochlos.[365] There are also signs of the existence of an oversea commerce and of a trade in olive oil with Egypt.[366]
