Some critics consider art/craftsmanship associated with the Celtic tradition to be inferior to more “advanced” civilizations. However the surviving Celtic artifacts belie the criticism. Celtic art/craftsmanship was equal to or superior to those of any comparable society.
All one needs to do to confirm this observation is to examine the surviving artifacts. The designs created by the early Celts are extremely intricate, detailed and interesting. Were they not of quality, these designs would not be used in numerous applications today (in jewelry, on tee shirts, in tapestries, on swords, and so forth).
In my view, it is absurd to find fault with Celtic craftsmanship/artistic talent when the evidence of their talent is obvious in the artifacts that survive from early Celtic times. I have only provided visuals of one such artifact of early Celtic art in the accompanying graphic but it seems sufficient to make the point. These images are of the Gundestrup Cauldron, which is indisputably of Celtic origin. It depicts various aspects of Celtic belief in extremely well crafted reliefs requiring considerable artistic talent. I urge you to look at other Celtic artifacts and judge for yourself whether the work is “of quality”.
