In "By the Waters of Babylon" what does the narrator experience in the "Place of the gods?"
The main events that occur in the Place of the Gods occur when the narrator manages to escape the dogs and finds himself in a building. Here the narrator experiences a vision of what happened to destroy the civilisation of "the Gods". He looks out and he sees "the city as it had been when the gods were alive." And then, as he marvels at the "magic" of the Gods, he sees their fate and how all of the amazing sights he looks at came to be destroyed:
It was fire falling out of the sky and a mist that poisoned. It was the time of the Great Burning and the Destruction. They ran about like ants in the streets of their city - poor gods, poor gods! Then the towers began to fall... I saw it happen, I saw the last of them die. It was darkness over the broken city and I wept.
Lastly, after this vision, John discovers the "dead God" who had obviously watched the destruction of his world. It is these two events that teach and show John that the "gods" were in fact not gods but men like himself, but men who had "wisdom beyond wisdom and knowledge beyond knowledge" and who "ate" that knowledge "too fast", resulting in their destruction and ruin.
