Demeter is the Greek goddess of harvest, agriculture, and fertility. She is also associated with the seasons, the cycle of life and death. Symbols include wheat, torch, cornucopia, and pig. She is the middle daughter of Cronus and Rhea. She had intercourse with Iasion in a ploughed furrow in Crete, and she gave birth to a son, Ploutos the god of wealth. Iasion was the son of the nymph Electra and Zeus and brother of Dardanus. In some variations of the Myth, Zeus out of envy promptly killed Iasion with a thunderbolt.

The most famous daughter of goddess Demeter is the virgin daughter Persephone that was abducted to the underworld by the God of Underworld Hades. Demeter searched for her ceaselessly, making her full grief and sadness. The seasons halted and all living things ceased their growth, then began to die. Faced with the extinction of all life on earth, Zeus sent his messenger God Hermes to the underworld to bring Persephone back. Hades agreed to release her if she had eaten nothing while in his realm; but Persephone had eaten a small number of seeds. This bound her to Hades and the underworld for certain months of every year, making her queen of the Underworld.

Furthermore, she has six more children: Despoina, Arion, Philomelus, Eubuleus, Chrysothemis and Amphitheus. Despoina is the goddess of mysteries of Arcadian cults. Arion extremely swift immortal horse which was able to speak. Philomenus was a minor demi-god, that invented the wagon or plough, and supported himself by ploughing his fields and cultivating crops. Eubuleus is a god well known from devotional inscriptions for mystery religions.
