p.39 "… (2000)… The Aryans left the shores of the Caspian and swarmed in every direction. They made their way into Turkestan, Iran, and India, and one tribe, the Mitanni, made a salient across the Tigris and Euphrates. The whole East felt the repercussions of this drive. The accession of the Xllth Dynasty (2000) was distinguished by hard struggles for the defence of Egypt, Canaan was born to a new life, shortly afterwards Troy II, the "Burnt City" was buried under two yards of debris, on which a simple village then arose, and in 1926 the Hittites subdued Babylonia. In Europe, too, it seems almost certain that peoples of Aryan origin arrived at this time. While the Proto-Latins were making their way towards Italy a race related to the Illyrians, the Hellenic race, made its appearance in the Balkan Peninsula. Soon the Achaians entered Thessaly, drove the old Pelasgian population into the surrounding hills, and installed themselves in the central region which was to keep their name."
p.53-54
"By dispersing themselves the Achaians had grown dangerously weak. In going off to every shore of the Mediterranean they left many gaps behind them. Gradually bands of the same race, speaking a dialect of the same language, came out of Illyria and made their way across Pindos, ever pressing further towards the South. The Dorians were coming into history."
p.64
"The Mycenaeans, however, did not always reject Minoan fashions. At Tiryns, on the frescoes of the First Palace, the men wear their hair at half-length, and have their faces shaven. Elsewhere bearded Mycenaeans are to be seen with their heads framed in curls; these are the "long-haired" Achaians of the Iliad ... In their turn the Dorians were to earn the epithet of men with "floating manes" and their descendants, the Spartiates of Thermopylai, still prepare for battle by combing their long hair."
"Jonathan having thus gotten a glorious victory, and slain two thousand of the enemy, returned to Jerusalem. So when he saw that all his affairs prospered according to his mind, by the providence of God, he sent ambassadors to the Romans, being desirous of renewing that friendship which their nation had with them formerly. He enjoined the same ambassadors, that, as they came back, they should go to the Spartans, and put them in mind of their friendship and kindred."
