Hello Maria,

I was also thinking of the Beltane Fires when everyone was encouraged to make love at the same time upon the earth to encourage the return of Spring, so very often personified as a young female.

“On May Eve the sexuality of life and the earth is at its peak. Abundant fertility, on all levels, is the central theme. The Maiden goddess has reached her fullness. She is the manifestation of growth and renewal, Flora, the Goddess of Spring, the May Queen, the May Bride. The Young Oak King, as Jack-In-The-Green, as the Green Man, falls in love with her and wins her hand. The union is consummated and the May Queen becomes pregnant. Together the May Queen and the May King are symbols of the Sacred Marriage (or Heiros Gamos), the union of Earth and Sky, and this union has merrily been re-enacted by humans throughout the centuries.”

I think it was called ‘Going A-Maying’.

Hieros gamos or Hierogamy (Greek ἱερὸς γάμος, ἱερογαμία “holy marriage”) is a sacred marriage that plays out between a god and a goddess, especially when enacted in a symbolic ritual where human participants represent the deities.

The White Goddess, by Robert Graves, is a stunning expose, and annotated and wonderfully indexed for a quick reference…almost as good as google.

However, he’s been tackled on some of his research and so is considered ‘out of date’.
