Bhutanese art is particularly rich in bronzes of different kinds that are collectively known by the name "Kham-so" (made in Kham) even though they are made in Bhutan, because the technique of making them was originally imported from the eastern province of Tibet called Kham. Wall paintings and sculptures, in these regions, are formulated on the principal ageless ideals of Buddhist art forms. Even though their emphasis on detail is derived from Tibetan models, their origins can be discerned easily, despite the profusely embroidered garments and glittering ornaments with which these figures are lavishly covered. In the grotesque world of demons, the artists apparently had greater freedom of action than when modeling images of divine beings.
