"As regards the narrative, it certainly seems to refer to some real event amongst the aboriginal tribes: namely, the quarrel between an elder and younger brother for the possession of a Ráj; and the subsequent alliance of Ráma with the younger brother. It is somewhat remarkable that Ráma appears to have formed an alliance with the wrong party, for the right of Báli was evidently superior to that of Sugríva; and it is especially worthy of note that Ráma compassed the death of Báli by an act contrary to all the laws of fair fighting. Again, Ráma seems to have tacitly sanctioned the transfer of Tárá from Báli to Sugríva, which was directly opposed to modern rule, although in conformity with the rude customs of a barbarous age; and it is remarkable that to this day the marriage of both widows and divorced women is practised by the Marawars, or aborigines of the southern Carnatic, contrary to the deeply-rooted prejudice which exists against such unions amongst the Hindús at large."
