(Jan 14, 2023) The same 3 types of mitochondrial genes show a different pattern during the late Bronze Age. Druid culture people are no longer in Malta, Crete (Minoan), and most of central Europe as a result of the Indo-European invasions. But for some reason they survived along the Rhine-Danube trade route linking Britain with the Black Sea with greatest survival rate being around the salt mine areas around Salzburg.
Organized salt mining began around Hallstatt (Salzkammergut region) in the Bronze Age starting around 1600 BCE. Before then water was boiled from salt springs to get the salt. This Central Celtic culture is different from the Eastern Celtic culture of pre-Roman Britain although an early connection does seem to exist.
