Fulacht Fiadh Find (Irish Coast)

Fulacht Fiadh (Archaeology Magazine)

This find in Galway is about 1,700 B.C., which is toward the end of Irish Beaker Age (EBA) but still comfortably in it.  Regardless of the periodization, these cists were used at some point in the Neolithic and probably to the modern age.  They were used to boil something, probably not food.

They are generally found in soggy places in the middle of nowhere.  Theories abound: baths, beer, leather working, etc.

Personally, my guess is they were used by furriers and long hunters for processing hides and pelts.
