In trying to ascertain the course of social development among the Greeks, the inquirer is met by an initial difficulty. The Greeks were not one great people like the Israelites, migrating into and settling in a new country, flowing with milk and honey. Their movements were erratic and various, and took place at very different times. Several partial migrations are described in Homer, and others are referred to as having taken place only a few generations back. The continuation of unsettled life must have had the effect of giving cohesion to the individual sections into which the Greeks were divided, in proportion as the process of settlement was protracted and difficult.
