The Eternal Savage by Edgar Rice Burroughs, Fiction, Fantasy

Nu, the son of Nu, his mighty muscles rolling beneath his smooth bronzed skin, moved silently through the jungle primeval. His handsome head with its shock of black hair, roughly cropped between sharpened stones, was high held, the delicate nostrils questioning each vagrant breeze for word of Oo, hunter of men. Now his trained senses catch the familiar odor of Ta, the great woolly rhinoceros, directly in his path, but Nu, the son of Nu, does not hunt Ta this day. Does not the hide of Ta's brother already hang before the entrance of Nu's cave? No, today Nu hunts the gigantic cat, the fierce saber-toothed tiger, Oo, for Nat-ul, wondrous daughter of old Tha, will mate with none but the mightiest of hunters. Only so recently as the last darkness, as, beneath the great, equatorial moon, the two had walked hand in hand beside the restless sea she had made it quite plain to Nu, the son of Nu, that not even he, son of the chief of chiefs, could claim her unless there hung at the thong of his loin cloth the fangs of Oo. "Nat-ul," she had said to him, "wishes her man to be greater than other men. She loves Nu now better than her very life, but if Love is to walk at her side during a long life Pride and Respect must walk with it." Her slender hand reached up to stroke the young giant's black hair. "I am very proud of my Nu even now," she continued, "for among all the young men of the tribe there is no greater hunter, or no mightier fighter than Nu, the son of Nu. Should you, single-handed, slay Oo before a grown man's beard has darkened your cheek there will be none greater in all the world than Nat-ul's mate, Nu, the son of Nu."
