researches

there are alot of people who are now linking old celtic mythology and
religion to vedic . you can find many web postings of this sort. was
caelleach kali? who knows.

most of the pages seem unsatisfying to me. few seem to be able to
read a celtic language.

of course i want to know details about prehistory that will likely
never be known
