The work brings together two central figures from Amazonian folklore, Iara and the Boto-cor-de-rosa (Pink River Dolphin), whose legends share the theme of enchantment that seduces and leads to loss. Iara, similar to mermaids in other cultures, appears as a woman of hypnotic beauty who, singing and combing her hair in the moonlight, lures men to the bottom of rivers. The Boto-cor-de-rosa, in turn, transforms into a man on party nights, seduces women and returns to the waters, leaving behind a trail of absence and guilt displaced onto the myth. There is an obvious irony in the encounter between these two entities: both are traditionally narrated as dangerous, seductive and responsible for the tragedies of others. By placing them face to face, the work challenges these narratives and exposes their moralising character, often used to control bodies, desires and behaviours, especially those of women. The myth ceases to be mere fantasy and begins to operate as social criticism, revealing how folklore also reflects inequalities, silencings and symbolic violence present in the history of the Amazon.
