Largely because the processes of transmission have been unkind, the religious hymns sung by the Greeks during worship of a god on a public or private occasion have received less than their due attention from modern scholars. Our sources frequently mention in passing that hymns were sung on the way to Eleusis, for example, or at the well Kallichoron on arrival at Eleusis, or by the deputations to Delos for the Delia, but they usually fail to record the texts or contents of these hymns. Until the fourth century BC temple authorities did not normally have the texts of cult songs inscribed; and the works themselves were by a diversity of authors, some well-known, some obscure, making the collection of their ‘hymns’ a difficult task for the Alexandrian compilers. Some such hymns were traditional—Olen's at Delos, for example — handed down orally from generation to generation; others were taught to a chorus for a specific occasion and then forgotten. Nor do the surviving corpora of ‘hymns’ — I refer to the Homeric Hymns, Callimachus' six hymns, and the Orphic Hymns—go very far to satisfy our curiosity as to the nature of this ubiquitous hieratic poetry. The Homeric Hymns would seem to have been preludes (προοίμια) to the recitation of epic poetry; they are in the same metre and style as epic, and the singer usually announces that he is about to commence another poem on finishing the hymn. Their content may give us authentic material about a god and his attendant myths, but the context of their performance seems distinct from worship proper. The Homeric Hymns provided the basic model for Callimachus' hymns although it is clear that he adapted the model to permit innovations such as the mimetic mode of hymns 2, 5 and 6, which present an eye-witness account of religious ritual. Some find Callimachus' hymns lacking in true religious feeling; few seriously maintain that they were intended, or could have been used, for performance in cult.
