How could Korean masked plays be used as rainmaking rites?

In the context of Korean performing arts, masked plays—specifically the folk masked dance plays known as sandae—can be performed as rainmaking rites.1

While these performances often feature satire, such as the criticism of corrupt officials or depraved Buddhist monks, the ritual function remains a significant aspect of the tradition. The use of masks in Korea has deep historical roots, dating back to at least the 3rd century CE, when they were employed to impersonate and placate animal spirits. By incorporating elements like singing, dancing, pantomime, and dialogue, these performances serve as a medium to engage with the spiritual realm, with villagers occasionally staging them specifically to invoke rain.12
