Cochihza, "she awakens the sleeping one", one says about the Cuicuitzcal swallow. Many words from the ancestors' language are derived from the root cochi - to sleep. It expresses both sleep and dream, but also lying down, dinner, subsistance, a cocoon built by caterpillars, eyelashes, leaving, yawning, making love to a woman, sleeping next to her, the place where one sleeps, waking up, pretending to sleep... Ometepe, the volcano island - Nicaragua. A landscape like a sleeping body. The Ancients describe life in two movements : one linear movement, like a walk; and one beat, emerging from the center. Each man adopts his own particular rythm at birth and keeps it for all his life. Within the encounter of the volcano's community and the guardians of its memory, a story of a world unfolds, a relationship to the island comes through.
