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 a New Testament verse (John 13:36). The verse, in the King James Version, reads as follows, "Simon Peter said unto him, Lord, whither goest thou? Jesus answered him, Whither I go, thou canst not follow me now; but thou shalt follow me afterwards."
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.
Sienkiewicz studied the Roman Empire extensively prior to writing the novel, with the aim of getting historical details correct. As such, several historical figures appear in the book. As a whole, the novel carries a powerful pro-Christian message.
Published in installments in three Polish dailies in 1895, it came out in book form in 1896 and has since been translated into more than 50 languages. This novel contributed to Sienkiewicz's Nobel Prize for literature in 1905.

Henryk Adam Aleksander Pius Sienkiewicz also known by the pseudonym Litwos, was a Polish writer, novelist, journalist and Nobel Prize laureate. He is best remembered for his historical novels, especially for his internationally known best-seller Quo Vadis (1896).

Born into an impoverished Polish noble family in Russian-ruled Congress Poland, in the late 1860s he began publishing journalistic and literary pieces. In the late 1870s he traveled to the United States, sending back travel essays that won him popularity with Polish readers. In the 1880s he began serializing novels that further increased his popularity. He soon became one of the most popular Polish writers of the turn of the 19th and 20th centuries, and numerous translations gained him international renown, culminating in his receipt of the 1905 Nobel Prize in Literature for his "outstanding merits as an epic writer."

Many of his novels remain in print. In Poland he is best known for his "Trilogy" of historical novels, With Fire and Sword, The Deluge, and Sir Michael, set in the 17th-century Polish-Lithuanian Commonwealth; internationally he is best known for Quo Vadis, set in Nero's Rome. The Trilogy and Quo Vadis have been filmed, the latter several times, with Hollywood's 1951 version receiving the most international recognition.
