This volume comprises the conference proceedings of the international and interdisciplinary meeting held in Leipzig from November 9 to 11, 2015. Scholars from different research areas present masks from Egypt, Israel/Palestine, Syria, Mesopotamia, Phoenicia, Cyprus, and Greece, mainly from the third to the first millennium BCE. The masks are analyzed from archaeological, iconographical, anthropological, philological, and theological perspectives. In many cases, the masks refer to gods, ancestors, spirits, and are used as a means to communicate between human beings and supernatural powers. Masks belong to the human condition and seem to be the international and intercultural answer to one of the most existential questions of human life. In addition, the volume includes an archaeological catalogue of the masks from Israel/Palestine of the Neolithic Age until the Persian Period.
