In the wetlands of West Bengal, where rivers braid into the Sunderbans and mist hangs low over shifting marshes, strange lights sometimes appear. Known as Aleya or “marsh ghost lights,” they hover above the swamps at dusk or in the dead of night, glowing pale white or blue. To fishermen navigating the creeks, they are both familiar and unsettling, flickering beacons that seem to beckon, then vanish just as suddenly.
Local folklore tells of wandering spirits, the restless souls of fishermen lost at sea, guiding or deceiving those who follow. Some swear the Aleya lures boats astray, leaving men stranded in the shallows, while others see it as a warning, steering them away from danger. Like their nets and oars, these tales form part of the heritage carried by Bengal’s fishermen.
Science offers a more grounded explanation. The marshlands are rich with decaying vegetation, releasing gases like methane and phosphine. When these rise and ignite, they create fleeting flames, natural, if unpredictable. Similar to will-o’-the-wisps in Europe, the Aleya lights are part of a global folklore of fire in the marsh. Yet in Bengal, their legend feels inseparable from the life of the fishermen, woven into the rhythm of river and tide.
Whether seen as spirit or science, the Aleya lights remain one of nature’s quiet enigmas. In the half-light of the Sunderbans, where mangroves meet the sea, the world still finds ways to glow with mystery.
