"To Melinoe, Fumigation from Aromatics. I call, Melinoe, saffron-veiled, terrene, who from Phersephone dread venerable queen, mixt with Zeus Kronion, arose, near where Kokytos' mournful river flows; when, under Plouton's semblance, Zeus divine deceived with guileful arts dark Phersephone. Hence, partly black thy limbs and partly white, from Plouton dark, from Zeus ethereal bright. Thy coloured members, men by night inspire when seen in spectred forms, with terrors dire; now darkly visible, involved in night, perspicuous now they meet the fearful sight. Khthonion queen, expel wherever found the soul's mad fears to earth's remotest bound; with holy aspect on our incense shine, and bless thy mystics, and the rites divine."
