Smaller kongs in past

These Kongs, the Storyteller explained, were some eighteen or twenty feet tall when standing erect — very much shorter than King Kong, but he had been born perhaps ten thousand years after the first settlement of the island by humans–I have no way of really knowing, for the islanders did not keep count of the years as we do. Calamitous events and their fallout made that impossible. For that matter, I do not know whether the Storyteller truly cares about that kind of exactness, since her preoccupation is always what moral or spiritual lesson may be gleaned. What matters here is that like the dinosaurs, the Kongs had been changed by Skull Island itself.

“The Kongs helped built the Wall, I know,” Ishara said. “You’ve told me that. But how did humans control the Kongs? They are huge, people say — as large as a dinosaur, and even more fierce.
“They were not always. Much larger than a man, three times as tall, but not as big or strong as they grew in later times. It has been long since anyone on this island has even seen a Kong.”
