Quo Vadis: A Narrative of the Time of Nero, commonly known as Quo Vadis, is a historical novel written by Henryk Sienkiewicz. Quo vadis is Latin for "Where are you going?" and alludes to the apocryphal Acts of Peter, in which Peter flees Rome but on his way meets Jesus and asks him why he is going to Rome. Jesus says "I am going back to be crucified again", which makes Peter go back to Rome and accept martyrdom.
The book Quo Vadis tells of a love that develops between a young Christian woman, Ligia (or Lygia), and Marcus Vinicius, a Roman patrician. It takes place in the city of Rome under the rule of emperor Nero around AD 64.
