Through these five invasions of Ireland, some questions arise about certain nations of ancient Europe. For example, during his journey through Europe, why did Galam Miledh not come across any Germen or Celts? Historians do not rule out the fact that Germen may be descendants of Scythians. But did they come from the East (the continent) or the West (the British Isles)?
It is remembered that after the last battle between the Nemedians and the Fomoraig, there were thirty survivors. Then, they divided themselves into three groups, specifying that one of the three took the direction of the island of Britain (Great Britain). The Book mentions (twice) the names of the thirty but without specifying their distribution in the three groups. But after mentioning the leader of the first group, Erglan, three names follow. Then after mentioning the leader of the second group, Britan, fifteen names follow. Finally, after naming the leader of the third group, Simeon, there are nine names left. The Book states that each group consisted of ten people but this is not consistent with the way the sequence of leaders and names is presented.
The group we are interested in is the Britan group which will be heading for the island of Britain. In this group, we find a member called German. As the populations of the time used to name themselves after a common ancestor, we can wonder if German is the ancestor of the Germen. In the same vein, the name of the Brittons, an ancient population of the northern coast of the European continent, could be a reference to Britan. These Brittons should not be confused with the Bretons.
Historians know that the Celts are descendants of Cimmerians from the Black Sea. They are also Indo-Europeans, but they did not have relations with the Scythians. The Greek historian Herodotus mentions them in his book at a time in their history when the Scythians were about to overwhelm them (we are around 600 BC). And they make the decision to migrate westwards up the Danube. Herodotus describes the debate among the Cimmerians between those who wanted to stay and those who wanted to leave. Today, historians know that they settled first on the territory of present-day Romania and then on the Danube Plain.
Finally, a third wave of Cimmerians emigrated even further west to the territory between the Paris Basin and the Alps. And these third wave Cimmerians called themselves the Kelti (Celts). It should be remembered that for the Romans, the Celts were one of the three populations of Gaul. The other two were the Belgians and the Aquitanians (Basques).
That said, everything indicates that Galam did not go to the Danube Plain and the German-Polish plain. And that he only went along Gaul. At that time, the population density of the Celts must not have been high. And the Germen were not necessarily deployed in the German-Polish plain. For example, geologists know that this plain was still below sea level 10,000 years ago. And we can assume that it was still swampy 2,500 years ago. Moreover, during Galam’s journey, the Book mentions the great northern ocean, and if it is the North Sea, we could deduce that this sea was larger than today.
