Grain and wine therefore have something in the nature of a soul, a specific life principle which makes them appropriate symbols not only of man’s cultural achievements, but also of the seasonally dying and resurgent god who is their life spirit.
Jung argues that grain and wine are polyvalent symbols bearing a ‘fourfold layer of meaning’ — agricultural, cultural, mythological, and sacramental — grounded in a ‘corn spirit’ or vegetation numen whose depth makes simple allegory inadequate.
