1The whole Celtic race has been regarded as descended from Gomer, though history suggests modern Celts are descended from both Gomer and Magog. Archaeologists and ethnologists agree that the first Indo-European group to spread across Europe were Celts. The Irish Celts claim to be to the descendants of Magog, while the Welsh Celts claim to be to the descendants of Gomer. Irish chronicles, genealogies, plus an extensive number of manuscripts which have survived from ancient times, reveal their roots. The Irish were descendants of Scythians, also known as Magogians, which is strongly supported by etymological evidence. Archaeological evidence shows that both the Celts (from Gomer) and Scythians (from Magog) freely shared and mingled cultures at their earliest stages. Russian and eastern European excavations plainly reveal the blending of these two groups. Their geographical locations (what is now eastern Europe, southern Russia and Asia Minor) were referred to by the Greeks under the name of Celto-Scythae, which was populated by the Celts to the south and west, and the Scythians to the north. The ancient Greeks first called the northern peoples by the general name of Scythae; but when they became acquainted with the nations in the west, they began to call them by the different names of Celts, including the Celto-Scythae. Celts and Scythians were considered essentially the same peoples, based on geography, though many independent tribes of Celts and Scythians existed. The Latins called them "Galli," and the Romans referred to them as "Gauls." Later names used by Greeks were the Galatai or Galatae, Getae, Celtae and Keltoi. In the third century before Christ (about 280 B.C.), the Gauls invaded Rome and were ultimately repelled into Greece, where they migrated into the north-central part of Asia Minor (Anatolia). Known as fiercely independent peoples, they conquered the indigenous peoples of that region and established their own independent kingdom. The land became known as Galatia. The Apostle Paul wrote his famous epistle to their descendants, the Galatians. Jewish historian Flavius Josephus wrote that the Galatians or Gauls of his day (93 A.D.) were previously called Gomerites.

Early Celtic tribes (from Gomer) settled much of the European theater, including present-day Spain, France, England and Germany, prior to contact with Scythians. For many centuries France was called Gaul, after the Celtic descendants of Gomer, whom ceded the territory to Romans and Germanic/Teutonic Franks (whence France) in the 4th century A.D. Northwest Spain is called Galicia to this day. Some of the Gomerites migrated further to what is now called Wales. The Welsh claim their ancestors "first landed on the Isle of Britain from France, about three hundred years after the flood." The Celtic language survives intact today mainly in the two variants of Welsh and Irish/Scottish Gaelic. The Welsh call their language Gomeraeg (after Gomer). The Celts of today are descendants of Gomer, and of the blended tribes of Magog and Gomer.
