The title of The Empusium, the newly translated work by Polish writer Olga Tokarczuk, winner of the Nobel Prize in Literature, is an invention. It is a portmanteau that fuses masculine and feminine literary allusions: first, Plato’s Symposium, which tells of a drunken Athenian banquet in which great statesmen give speeches on the nature of love; second, the empusa, a shape-shifting female demon who, according to Greek mythology, had the sirenic ability to lure and prey upon young men.
