Betafo ("many roofs) is a village and fokontany in the municipality Arivonimamo II,[2] in the district of Arivonimamo, in the region of Itasy, Madagascar.
The village's inhabitants are said to be divided between descendants of nobles (andriana) and descendants of former slaves (olona mainty, literally "black people"). This aspect was the subject of a study by anthropologist David Graeber.[3] His book, , contains a detailed recounting of the village's oral traditions, full of stories of scandalous murders, magical battles, forbidden romances, and spiteful ancestors sending fires and hailstorms from their tombs.
