It is not unlikely that the Kizilbash are lineal descendants of the Galatae of Asia Minor. This western people entered the peninsula through the notch cut by the valley of the Sakaria--an avenue also chosen by the Phrygians sung by Homer. Later the Cimmerians also followed the same route. All these invasions from the west brought blondness into Turkey--though not of the pure Nordic type, for the roads leading out of northern Europe had their longest stretches in the brunet territory of central and southern Europe. Nevertheless mingling incurred in the course of migration, as well as after settlement, has not obliterated entirely the fair ancestral type. The strongest argument in favor of the relationship between the Galatae and the Kizilbash lies in the identity of the territory occupied by both peoples. The racial distinction between the two lies in the greater admixture of Tatar blood in the Kizilbash of our times. Gradual change of the Galatian of European provenience into the Kizilbash type of Asiatic affinity was accompanied by the replacement of Celtic by Tatar culture. Galates to the Greeks meant any western barbarian. The term was applied to the foreigners whose coming was always marked by destruction and who, in the third and second centuries B.C., terrorized Thrace before crossing into Asia Minor. Here they introduced Celtic forms of speech which were current in their settlements as late as the fourth century of our era. At that time the language spoken in parts of Anatolia was similar to the dialect of the Traveri, a Celtic tribe on the Moselle whose name has been perpetuated in that of the city of Trèves.[226] Arrian, a native of Bithynia, describing the customs of the Celts gives accounts of usages, such as the worship of the oak, which prevailed in his country and which on investigation are found to have their counterparts in Europe. In religious thought, the Kizilbash may be classed as the most liberal among the Mohammedans of Turkey. Their interpretation of the Koran exempts them from keeping fasts and allows them the use of wine. They permit their women to go about with a freedom which has never been tolerated among Sunnis. Christian rites, such as the custom of praying over bread and wine, are performed among them. Fragmentary survivals of pagan observances likewise form part of their worship.
