"Artistic Cultures - the Ecstatic culture

This is a general term suggested for situations in which some type of artistic creation - though it is usually more than merely artistic - occurs in the midst of a mediumistic trance performed for mystical or magical purposes, as a consequence of a mystical experience, or even as an element of prophecy. Art arises from emotionally intense experiences, 'divine madnesses', which are perceived to have high symbolic significance."
