Thanks for the link. It is interesting, but like most traditional authors they got the Celtic migrations wrong because their premise was defective. They assumed the Celts somehow magically BEGAN in the region of Hallstadt Austria and LeTennes Switzerland (I have been to both places) and migrated outward from there. In fact, these were only major way stations in the Celtic migration westward and northward from the Caucasus.
"Mass migrations during the Bronze Age scattered many peoples across Europe and Asia ..."
it triggers in me the response, "but these were the CELTS!"
If you start out in the Caucasus with 5 MILLION Lost Tribe/Celts in the year 620 BC and they were last seen headed West, you can have a LOT of these little "mass migrations" happening at the same time, but too many academics can't seem to connect them together. Can't see the forest for all those trees in the way. My contention is that if we look at the similarities of these apparently random groups of people drifting in waves mostly northwestward across the countryside, we may find that they are just different clans or tribes of the same people.
(But academic careers are not made by finding answers, they are made by learning more and more about less and less until one knows everything about nothing. Then one is called wise, and if not rocking any boats along they way by doing truly independent thinking, obtains tenure.)
