The cauldron's authenticity as an Iron Age object is not in question; the debate is over origin. Silver is rare in Celtic metalwork but common in the Lower Danube, and the repousse technique and much of the ornament match Thracian and Dacian silver, while the subject matter, torcs, a wheel-god, a horned figure, war-trumpets, is Celtic. The consensus places its manufacture in the Lower Danube, in Thrace or Dacia, in the second or first century BC, made either to Celtic taste or for a Celtic patron. As the specialists Julia Farley and Fraser Hunter put it, the cauldron is not Celtic, or at least not only Celtic. The horned figure's frequent identification with the god Cernunnos is plausible but not certain.
Where the cauldron was actually made remains genuinely disputed among specialists: its imagery and iconographic style are widely read as Celtic or La Tene, yet its silverworking technique has been argued by some scholars to point instead to a Thracian workshop tradition from the Lower Danube region, in what is now Bulgaria or Romania, a debate that has not been resolved to general scholarly agreement. What is not disputed is that the cauldron was not made in Denmark, where it was found; it was deposited there, likely after having travelled a considerable distance, whether as loot, trade goods or a diplomatic gift, from wherever its actual workshop of origin lay.
