According to Greek Mythology, Persephone, the queen of the underworld, was the daughter of Zeus and Demeter, the goddess of harvest and fertility.

Hades, the god of the Underworld abducted Persephone. Her distraught mother wandered the earth looking for her daughter, abandoning her duties as the goddess of harvest and fertility, with devastating consequences. The earth began to dry up, harvests failed, plants lost their fruitfulness, and famine spread the Earth. The cries of the people who were suffering reached Olympus, compelling her father Zeus to intervene.

Hearing of this, Hades tricked his reluctant bride, into eating a few seeds of the pomegranate fruit. This was the food of the Underworld and every time someone ate even a few seeds of this, they would always return.

Zeus intervened, decreeing that Persephone would spend six months with her husband in Hades and six months with her mother on Olympus.

During the six months that Persephone spent in the Underworld, her mother was sad, leaving the Earth to decline.

Whenever Persephone went to Olympus, Demeter would shine from happiness and the land would become fertile and fruitful again. These were the months of Spring and Summer.

This myth is an allegory for the eternal cycle of the nature and humanity's death and rebirth.
