This paper aims to elucidate certain features of Callimachus' Fifth Hymn in ways, which, I hope, will be suggestive for the criticism of all the Hymns. In particular, I am interested in exploring how the mythic and religious dimensions of Callimachus' poetry can be sensibly discussed, while doing justice to the very strong sense of a changed world which the poems evoke; to this end the concluding section of the paper briefly examines related aspects of the Sixth Hymn to Demeter.
