The "prince of Lavau" was discovered in 2014, lying buried in a tumulus near the outskirts of Troyes. The skeleton and its rich surroundings pointed towards a male Celt from somewhere around the fifth century B.C., who had been a person of considerable importance and wealth.

The documentary compares this recent find to earlier finds, not only in the area but also in neighbouring countries, and concludes that the Celts were canny traders who made excellent use of a whole network of roads and waterways. The documentary also concludes that the Celts - or at least those Celts who were rich and well-connected - had access to gems and riches from all over Europe, including giant drinking vessels from Greece and Italy (parrrty !) and amber pendants from the Baltic. These same Celtic peoples seem to have occupied a considerable territory, which both invited and necessitated busy mutual contacts across a variety of borders.

It's a well-made and interesting documentary, which tries to cast a light on the long-lost world of the Celts, at least during a specific era in time. Much is discussed : the building of settlements and fortifications, the organisation of society, the obsession with aristocratic generosity and prestige, the importance of trade and commerce, the funeral rites.

In other words : a must-see for anyone interested in the early history of Europe, and an eye-opener for those who believe that globalization is a purely modern phenomenon.
