Hadon of Ancient Opar
Philip José Farmer
 The novel deals with the expedition of Hadon, a young Oparian warrior, to the Wild Lands and as far as the mysterious Ringing Sea, which would one day be called the Mediterranean, with the strange woman whom he meets and brings with him, and with the cataclysmic civil war which breaks out on his return and which he partly (and completely unintentionally) helps touch off. The ancient Khokarsan society of which Opar is a part is a matriarchy (a reasonable inference from the culture of the later-day Opar encountered by Tarzan). A delicate balance between the genders is maintained, symbolized by the co-rule of the high priestess and the king (whose main authority is command of the army), which corresponds to some theories of sociologists and historians on the way actual matriarchal societies may have worked. The same scheme is repeated on a smaller scale on the local level, where towns are co-governed by a local priestess and the commander of the local garrison. The current king, Minruth, tries to subvert this immemorial system and establish exclusive male power, which incidentally would force an incestuous relationship upon the current high priestess, Awineth, who happens to be his daughter. Lalila, the foreign "White Witch from the Sea," whom Hadon brings with him and with whom he falls in love, is used as a pawn in King Minruth's power game; the xenophobic suspicions aroused about her are used in an attempt to undermine the position of women in general. Hadon and his male and female friends rally to the high priestess' banner against the king's evil schemes.
