Agree -- the most revealing thing this article exposes is the author's ignorance of classical history. Peoples migrated just as far then as they do now, and there are many references to Gauls in Anatolia in ancient history.
Ah well, it was an interesting read, worth checking out.
Agreed. There is a powerful tendency for historians, archeologists and anthropologists to isolate peoples by space, as well as time, and assume they never traveled farther than the horizon. That way its easier to make silly assumptions which justify ridiculous conclusions about what they did, and thought, and traveled, etc.
In fact, while travel has never been as easy as it is today, traders and warriors and others from many cultures have always traveled widely.
