129     Ibonia's story, Becker says, underlines vividly the great danger in monogamy--remaining without posterity. The sterility of the mother and the rape of the wife have come close to extinguishing the dynasty. Monogamy is the luxury of a few privileged families who are watched over by pweros above and who can command supernatural forces on earth. The contradictions leads Becker to see in the edicts a moral added too late to be well motivated. The motivation, however, may have been topical. Here, as the bard begins to move his audience out of the fictional world of his tale back to the waking life of the court, the parallels between Ibonia and historical Merina sovereigns become clear. The edicts of Andrianampoinimerina about marriage, well known to a royal audience, are a climactic episoe of the Tantaran'ny Andriana (Callet, Tantaran'ny Andriana, 3:144:-52; Delivre, Histoire des rois d'imerina, 31-33). The immediacy of the concern about marriage across caste lines, at the time Dahle transcribed Ibonia, is clear from the laws regulating matrimonial alliances that were promulgated by Ranavalona II in 1881. Ottino traces th is concern back to India (L'Etrang¸re, 556-78).
