Adena Religion
Although the mounds are beautiful artistic pieces themselves, Adena artists created smaller, more personal pieces of art. Many pieces of art seemed to revolve around shamanic beliefs.Also the transformation of humans into animals (particularly birds, wolves, bears and deer) and back to human form. Deer antlers, both real and constructed of copper, wolf, deer and mountain lion jawbones, and many other objects were fashioned into costumes, necklaces and other forms by the Adena. This concludes that there may be a chance the Adena practiced Shamanism.
Art
The Adena carved tables, made pottery, and made artworks based on their religion. The Adena carved small stone tablets, usually 4 or 5 inches by 3 or 4 inches by .5 inches thick. Paint has been found on some Adena tablets, leading archaeologists to conclude that these stone tablets were probably used to stamp designs on cloth, animal hides, or onto their own bodies for tattooing. Unlike in other cultures, Adena pottery was not buried with the dead or the remains of the cremated, as were other pieces. Usually with grit or crushed limestone, it was largely plain, cord-marked or fabric marked. The vessel shapes were flat-bottomed jars, sometimes with small foot-like supports
