("many roofs") refers to (1) a town and surrounding district in the Antananarivo Province
, and (b) a village in the district of Arivonimamo, in the same provide. The village's inhabitants are said to be divided between descendants of andriana ("nobles') and descendants of former slaves ("olona mainty"). This aspect was the subject of a study by anthropologist David Graeber. His book, "Lost People: Magic and the Legacy of Slavery in Madagascar" 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.
