The last accession which the population of Europe received was accomplished by an irruption similar to that of the Huns, but on a grander scale. In the beginning of the fifteenth century the Osmanli Turks swept across the Hellespont and Bosphorus, and in 1453 established their empire in Europe by the capture of Byzantium. In proportion to its numbers, no race ever gave such a shock to the Western world as this; and, by its very antagonism, it helped to quicken into life the population and kingdoms of central and eastern Europe. It is semi-Caucasian by extraction, but, coming from the northern side of the Caucasus, and pretty far to the east, the original features of the race had a strong dash of the Tartar in them. The portrait of Mahomed II., the conqueror of Byzantium, may be taken as a fair sample of the primitive Turkish type,—indeed a more than average specimen, for among all nations the nobles and princes, as a class, are ever found to possess the most perfect forms and features. The Turkish tribes who still follow their ancient nomadic life, and wander in the cold and dry deserts of Turkistan, still exhibit the Tartar physiognomy—even the Nogays of the Crimea, and some of the roving tribes of Asia Minor, present much of this character. The European Turks, and the upper classes of the race generally, exhibit a greatly superior style of countenance, in consequence of the elevating influences of civilisation, and of their harems having been replenished for four centuries by fair ones from Georgia and Circassia,—a region which, as Chardin long ago remarked, “is assuredly the one where nature produces the most beautiful persons, and a people brave and valiant, as well as lively, _galant_, and loving.” There is hardly a man of quality in Turkey who is not born of a Georgian or Circassian mother,—counting downwards from the Sultan, who is generally Georgian or Circassian by the female side. As this crossing of the two races has been carried on for several centuries, the modern Ottomans in Europe are in truth a _new nation_—and, on the whole, a very handsome one. The general proportion of the face is symmetrical, and the facial angle nearly vertical,—the features thus approaching to the Circassian mould; while the head is remarkable for its excellent globular form, with the forehead broad and the glabella prominent.
