• The carbuncle as a Christological symbol of atmosphere in Nicholas of Cusa - with reference to the late antique and medieval gemstone allegory. In his De non aliud, Nicholas of Cusa applies the carbuncle as a Christological aenigma, which can be understood as an exemplary object of atmosphere due to its dual nature of light substance and mineral substance. The article will show that the meaning of the carbuncle image as the epistemological method is so closely linked to the character and form of thought in De non alud that an examination of the meaning of the carbuncle in its historical allegory contributes to the question of image theory in Cusanus. By that the question is answered to which extent this far-reaching meaning of the carbuncle can shed light on the anagogic dimension of the perception of atmosphere.
