Here's why:
* Pig Sacrifice: Pigs were often sacrificed to Demeter in ancient Greece, particularly during the Thesmophoria festival, a festival dedicated to Demeter and Persephone.
* Fertility Symbol: Pigs were seen as symbols of fertility and abundance due to their prolific breeding habits.
* Agricultural Connection: Pigs were important for agricultural purposes, helping to till the soil and provide food.
While the pig is the most well-known, some sources also mention the snake as a sacred animal associated with Demeter. This connection might stem from the association of snakes with the Earth and its life-giving properties.
However, it's important to note that Demeter is not exclusively linked to any single animal. Her connection to both the pig and the snake reflects her role as a fertility goddess and her strong ties to the natural world.
