There are two ways to think about time: as a circle and as a line.
The ancient Greeks—like other cultures that relied on farming for food—saw time as a circle, as cyclical. They planted in the Spring;, they weeded and pruned in the Summer; they harvested in the Autumn; they waited through the Winter for the cycle to start over again.
Let me tell you the Greek myth of Persephone. Persephone was the beautiful daughter of Demeter, the goddess of fertility and harvest. Demeter made the seeds take root, the flowers blossom & the fruit ripen. Demeter loved Persephone and everything was literally sunshine and daffodils all year long. At least it was until Hades, the dark god of the Underworld, saw the beautiful Persephone and decided to steal her away to be his wife. Demeter was heartbroken—and while Persephone was gone, Demeter neglected her goddess-duties until the world became cold and barren. Frosty wind killed all the crops; fruit withered on the vine. No grain to harvest meant no pita bread for gyros. No cucumbers for tzatziki sauce. No falafel. The situation became desperate! Finally Zeus stepped in and made them strike a deal: Hades would keep Persephone only half of each year and let Persephone spend the other half with her mom. So while Persephone lives in the Underworld, it’s winter. When Persephone is reunited above-ground with Demeter, there is planting and growth and harvest.
This is an example of thinking of time as a cycle.
