The Laboya are one of the many ethnic communities (suku in modern Indonesian terminology) inhabiting the western end of the island of Sumba in Eastern Indonesia. The indigenous religion was a form of ancestor worship. The more distant an ancestor was, the more powerful this ancestor was believed to be. The founding ancestors, called marapu as elsewhere in Sumba, were believed to have had godlike powers. More ordinary spirits of the dead were believed to undergo a series of transformations, eventually becoming clouds and rain.
