Quo Vadis: A Narrative of the Time of Nero (Quo vadis: Powieść z czasów Nerona) is a historical novel written by Henryk Sienkiewicz in Polish. The novel tells the story of a romantic love that develops between Lygia (Ligia in Polish), a Christian woman and barbarian hostage, and Marcus Vinicius, a young Roman patrician. It takes place in the city of Rome under the rule of Roman emperor Nero, from c. AD 64 to AD 68, when he committed suicide.
Sienkiewicz studied the history of the Roman Empire extensively before writing the novel, with the aim of getting historical details correct. Consequently, several historical figures appear in the book. As a whole, the novel carries a pro-Christian message. It was first published in instalments in the Gazeta Polska between 26 March 1895 and 29 February 1896, as well as in two other journals, Czas and Dziennik Poznański, starting two and three days later. It was published in book form in 1896 and has been translated into more than 50 languages. The novel contributed to Sienkiewicz's Nobel Prize in Literature in 1905.
