Analysis of information sources in references of the Wikipedia article "Vix Grave" in English language version.
The present treatment draws on Piggott's (1975:186–187) suggestion that this individual [the Lady of Vix], as a member of an 'heroic' social order stretching back to the second millennium BC, could be a representative of a priestly class in existence by the late Hallstatt period. Piggott sees these individuals as the forerunners of the Druids of the later Iron Age.
Various authors have suggested that the lady who was buried at Vix could have exercised a role as a priestess during her lifetime; among other indications, the silver phiale for libations found on her grave is interpreted as evidence for this hypothesis. Such a religious function would in no way have been incompatible with her simultaneous role as 'queen'.
