Duduk is the patron of rain in Talysh folk religion, a benevolent power who sends the seasonal downpours that sustain the humid, forested agriculture of the Talysh mountains and bestows grace and abundance upon the land. His figure belongs to the oldest, nature-cult layer of the Talysh worldview, in which weather, fertility and the well-being of the community are governed by named powers rather than impersonal forces. Sources preserve him chiefly through rain-invocation practice and folk song rather than through a developed narrative cycle.
