Marinette is a fierce and greatly feared lwa of the Petwo rite of Haitian Vodou, associated with the owl, with fire, and with the revolt that founded the Haitian nation, and she is invoked in matters of vengeance and of hard protection. To understand her rightly, it helps to understand the Petwo rite to which she belongs.
Where the Rada lwa are the cool, benevolent, ancestral spirits of West African origin, the Petwo spirits are hot, fierce and quick to act, a family of lwa forged in the New World, in the crucible of enslavement, suffering and resistance, and carrying the anger and the fighting spirit that the condition of slavery demanded. The Petwo lwa are not evil; they are the spirits of force and defence, served when strength, speed and protection against enemies are needed, and they are approached with care and respect for their power. Marinette is among the most powerful and dangerous of them. She is remembered in connection with the ceremony traditionally said to have launched the Haitian Revolution, the great uprising of the enslaved that overthrew slavery and colonial rule, so that her fierceness is bound up with the fight for freedom itself. She is imagined as wild-haired and formidable, linked with the owl and with fire and with the night, and she is served with caution and with respect for the seriousness of what she is called upon to do. Vodou is a living religion, and its Petwo spirits are an essential part of it, born of a real and terrible history; Marinette is one of the fiercest of these spirits of fire and defence, a lwa of vengeance and hard protection whose power is treated with the gravity it demands.
