The Pipes of Pan, by Lester del Rey (epub/Kindle)

Pan recognized the lazy retreat to nature that had replaced his strong worship of old. He moved carefully through the tangled growth that made way for him, his cloven hoofs clicking sharply on the stones. It was a thin and saddened god that approached the house and gazed in through a hole that served as a window.

Inside, Frank Emmet lay on a rude pallet on the floor, a bag of his possessions beside him. Across from him was a stone fireplace, and between the two, nothing. A weak hand moved listlessly, brushing aside the vermin that knew his sickness; perhaps they sensed that the man was dying, and their time was short. He gave up and reached for a broken crock that contained water, but the effort was too great.

“Pan!” The man’s voice reached out, and the god stepped away from the window and through the warped doorway. He moved to the pallet and leaned over his follower. The man looked up.
