"In later life I have been sometimes praised, sometimes mocke..." — Robertson Davies quote meaning

In later life I have been sometimes praised, sometimes mocked, for my way of pointing out the mythical elements that seem to me to underlie our apparently ordinary lives. Certainly that cast of mind had some of its origin in our pit, which had much the character of a Protestant Hell. I was probably the most entranced listener to a sermon the Reverend Andrew Bowyer preached about Gehenna, the hateful valley outside the walls of Jerusalem, where outcasts lived, and where their flickering fires, seen from the city walls, may have given rise to the idea of a hell of perpetual burning. He liked to make his hearers jump, now and then, and he said that our gravel pit was much the same sort of place as Gehenna. My elders thought this far-fetched, but I saw no reason then why hell should not have, so to speak, visible branch establishments throughout the earth, and I have visited quite a few of them since.
