Prehistoric archæologists have found in Europe many specimens of ornamental sculpture and engraving belonging to the Paleolithic age, but the cross is not known in any form, Swastika or other. In the Neolithic age, which spread itself over nearly the entire world, with many geometric forms of decoration, no form of the cross appears in times of high antiquity as a symbol or as indicating any other than an ornamental purpose. In the age of bronze, however, the Swastika appears, intentionally used, as a symbol as well as an ornament. Whether its first appearance was in the Orient, and its spread thence throughout prehistoric Europe, or whether the reverse was true, may not now be determined with certainty. It is believed by some to be involved in that other warmly disputed and much-discussed question as to the locality of origin and the mode and routes of dispersion of Aryan peoples. There is evidence to show that it belongs to an earlier epoch than this, and relates to the similar problem concerning the locality of origin and the mode and routes of the dispersion of bronze. Was bronze discovered in eastern Asia and was its migration westward through Europe, or was it discovered on the Mediterranean, and its spread thence? The Swastika spread through the same countries as did the bronze, and there is every reason to believe them to have proceeded contemporaneously--whether at their beginning or not, is undeterminable. The first appearance of the Swastika was apparently in the Orient, precisely in what country it is impossible to say, but probably in central and southeastern Asia among the forerunners or predecessors of the Bramins and Buddhists. At all events, a religious and symbolic signification was attributed to it by the earliest known peoples of these localities. M. Michael Zmigrodzki, a Polish scholar, public librarian at Sucha, near Cracow, prepared and sent to the World's Columbian Exposition at Chicago a manuscript chart in French, showing his opinion of the migration of the Swastika, which was displayed in the Woman's Building. It was arranged in groups: The prehistoric (or Pagan) and Christian. These were divided geographically and with an attempt at chronology, as follows: I. Prehistoric: 1. India and Bactria. 2. Cyprus, Rhodes. 3. North Europe. 4. Central Europe. 5. South Europe. 6. Asia Minor. 7. Greek and Roman epoch--Numismatics. II. Christian: 8. Gaul--Numismatics. 9. Byzantine. 10. Merovingian and Carlovingian. 11. Germany. 12. Poland and Sweden. 13. Great Britain.
