The Homeric Hymn to Demeter is considered one of the most important of the Homeric Hymns by modern scholars. It is one widely discussed in scholarly literature due to its important association with the Eleusian Mysteries.
Recent scholarship emphasis connectioon of myth to explication of pre-existing rituals (Burkert) and gender analysis (Foley). Joseph Campbell's JUngian readings, although still havoing some traction in popular culture are too speculative and lacking in empirical support to be part of the scholarly conversaation.
Greek myth, according to leading scholar Walter Burkert, is secondary to ritual, and created to give a credible explication or backstory of existant cultic practices. The Homeric Hymn to Demeter explains (1) the rites of Demeter as corn goddess, including the showing of the ear of corn at the mysteries and (2) the specific culytic foundation at Eleusis, which is explained by Demeter herself who describes the temple she requires and that it should be erected at Eleusis when she reveals her true nature.
