A Rock Song About Faunus

I think I must read The Wind in the Willows, published in 1908. A kindly Pan makes an appearance in Chapter 7, entitled, "The Piper at the Gates of Dawn". Like some of E.M. Forster's work, it's a little bit of a Chronicles of Narnia for classical religions:

Perhaps he would never have dared to raise his eyes, but that, though the piping was now hushed, the call and the summons seemed still dominant and imperious. He might not refuse, were Death himself waiting to strike him instantly, once he had looked with mortal eye on things rightly kept hidden. Trembling he obeyed, and raised his humble head; and then, in that utter clearness of the imminent dawn, while Nature, flushed with fullness of incredible colour, seemed to hold her breath for the event, he looked in the very eyes of the Friend and Helper; saw the backward sweep of the curved horns, gleaming in the growing daylight; saw the stern, hooked nose between the kindly eyes that were looking down on them humourously, while the bearded mouth broke into a half-smile at the corners; saw the rippling muscles on the arm that lay across the broad chest, the long supple hand still holding the pan-pipes only just fallen away from the parted lips; saw the splendid curves of the shaggy limbs disposed in majestic ease on the sward; saw, last of all, nestling between his very hooves, sleeping soundly in entire peace and contentment, the little, round, podgy, childish form of the baby otter. All this he saw, for one moment breathless and intense, vivid on the morning sky; and still, as he looked, he lived; and still, as he lived, he wondered.

'Rat!' he found breath to whisper, shaking. 'Are you afraid?'
'Afraid?' murmured the Rat, his eyes shining with unutterable love. 'Afraid! Of HIM? O, never, never! And yet—and yet—O, Mole, I am afraid!'
Then the two animals, crouching to the earth, bowed their heads and did worship.

Van Morrison wrote a song about it. 

You might object: This isn't classical religion. It's modernism, humanism, romanticism, and writers who were immersed in the classics, such that it naturally came out in their writing. I would disagree. Formative influences are not to be confused with the thing itself, and the reinterpretation of a religious spirit or religious forms under later cultural and historical conditions is what humans do. Think of all the sects of Christianity, from St. Thomas's church in India in the first century to contemporary megachurches with rock bands. Yet, we group the multitude of those sects from all time periods and places within the same broad label. So, to dismiss this too readily as not being classical religion is, in my view, an error.
