The two-day international conference will bring together scholars to reflect, from comparative and intercultural perspectives, on the ways in which Caucasian Christianities perceived, represented and made use of the sign of the cross. It will particularly tackle aspects of materiality, performativity and visualisation of the cross in medieval Armenian, Georgian and neighbouring traditions, by focusing on such questions as: the dynamic interaction of cross objects with built and natural spaces; materials of the cross in their practical, symbolic and allegorical dimensions; local, regional and trans-regional cult phenomena associated with crosses; liturgical uses of the cross; cross as expression of individual devotion and its involvement in burial practices, pilgrimage and medicine.
