This article reconsiders the historical and typological relation between Greek maturation rituals and Greek mystery religion. Particular attention is given to the word κλεινός (‘illustrious’) and its ritual uses in two roughly contemporary Late Classical sources: an Orphic-Bacchic funerary gold leaf from Hipponion in Magna Graecia and Ephorus’ account of a Cretan pederastic age-transition rite. In both contexts, κλεινός marks an elevated status conferred by initiation. (This usage finds antecedents in Alcman'sPartheneia.) Without positing direct development between puberty rites and mysteries, (...) the article argues on the basis of shared vocabulary and other ritual elements that age-transitions influenced the ideology of mystery cults. It is further claimed that puberty rites and mysteries performed similar functions in their respective social contexts, despite obvious differences of prestige and visibility. Age-transition rites have been analysed in Bourdieu's terms as ‘rites of institution’, in which young elites were publicly affirmed in civic roles: private mysteries can be described in analogous but opposed terms as rites of ‘counter-institution’, in which familiar ritual language and symbols of elite status were used to construct an alternative ‘imagined community’ of mystery initiates.
