Jurgen by James Branch Cabell

Next the tale tells how three inferior devils made a loud music with bagpipes as Jurgen went into the Black House of Barathum, to talk with Grandfather Satan.

Satan was like a man of sixty, or it might be sixty-two, in all things save that he was covered with gray fur, and had horns like those of a stag. He wore a breechclout of very dark gray, and he sat in a chair of black marble, on a dais: his bushy tail, which was like that of a squirrel, waved restlessly over his head as he looked at Jurgen, without speaking, and without turning his mind from an ancient thought. And his eyes were like light shining upon little pools of ink, for they had no whites to them.
