Since I haven't read this - here is a review from Science Fiction Review (#13, May 1975) :
Rather than watch the MARY TYLER MOORE SHOW, I will review a pretty damn good Philip Jose Farmer novel, HADON OF ANCIENT OPAR. The star of the book isn't Hadon, a nice kid with athletic and fighting skill; it is the ancient world Phil has created, its peoples, customs, its religions and politics...and above all its critical geography. Phil went to the trouble of writing a history of civilization on the shores of the twin island seas existing in central Africa from 12,000 BC to 10,000 BC. This history is in the back of the book and it enhances your enjoyment of the story if you read the history first and study the maps of the Kemu (northern sea) and the Kemuwopar (southern sea) and Khokarsa island. The novel incorporates the adventures of Hadon, winner of the Great Games (to-the-death Olympics) and his 300-pound warrior relative Kwasin, the beautiful Lalila, the off-stage Shahindar, the man-God who came from the far future and taught the central African peoples key knowledge and attitudes to establish the high bronze-age civilization of the inland seas.

Hadon is a true hero, but it is Kwasin (rapacious, uninhibited, fierce, a liver of life to the hilt) who seems to have had the most fun in life. Maybe one of these days, when the basic anti-sex and anti-pleasure bias of Anglo-Saxon civilization has changed significantly, the Kwasins of fiction will properly be given center stage and the idealistic, over-controlled, self-sacrificing (fools?) like Hadon will be shoved aside as uninteresting and unrealistic. Granted Hadon is not as idealistic or controlled or self-sacrificing as Heroes of a few years ago, but he still is Too Much in my view, given the short, brutal, dirty lives of 99.9% of the peoples of the era. Well, that's neither here not there for this review's purposes. If you like deadly action, a quest, a catastrophe or two, a gripping dungeon escape, a chase, battles and fights galore, coherent exotic religions, customs and behavior, be assured that Phil Farmer does not stiff you in this book; its all there and more.
