Poppi, Cesare (1980) Kinship and social organization among the Ladins of the Valdi Fassa (northern Italy). Cambridge Anthropology 6(1-2): 60-88.

Poppi, Cesare (1992) Building difference: the political economy of tradition in the Ladin Carnival of the Val di Fassa. In: Revitalizing European Rituals. Jeremy Boissevain (ed.) Pp. 113-136. London : Routledge
