In the first century B.C., the Celts were famed throughout the ancient world for their savagery, reputed to be cannibals and headhunters. A young Greek philosopher called Posidonius decided to discover the truth about the Celts for himself and embarked on one of the great adventures of his age. Journeying deep into Gaul, decades before Caesar conquered Gaul, Posidonius discovered the Celts to be a sophisticated people who studied astronomy, composed poetry and gave their women a greater degree of freedom than any other society at the time. Posidonius was to record Celtic civilisation in its final decades, when druids held the central role in its society, before its destruction by Rome.
