Ceres is the goddess of grain, agriculture, the love a mother bears for her child, of the earth and earthly rootedness, and of the things that grow out of the ground. Ceremony is late-fourteenth-century cerymonye, from Latin caerimonia, holiness, sacredness, awe, reverent rite. It is possibly an Etruscan word or a reference to the ancient rites performed at Caere by the Etruscan priests.
Consider the tangles of love, the rite of the love a mother bears for her child, the rite of the love with which a child mothers her mother.
