Pigs have historically been significant in various cultures, often symbolizing wealth, fertility, and abundance. In Greek mythology, pigs were associated with the followers of Dionysus, while in Norse mythology, wild boars represented strength. The association of pigs with grounded, earthly qualities may have contributed to the absurdity of the idea that they could fly, thereby reinforcing the idiom's meaning of impossibility.
