What was the first name of the eponymous Ben-Hur?

Ben-Hur is a 1959 American epic historical drama film, directed by William Wyler, produced by Sam Zimbalist for Metro-Goldwyn-Mayer and starring Charlton Heston, Stephen Boyd, Jack Hawkins, Hugh Griffith and Haya Harareet. A remake of the 1925 silent film with the same name, Ben-Hur was adapted from Lew Wallace's 1880 novel Ben-Hur: A Tale of the Christ. The screenplay is credited to Karl Tunberg but includes contributions from Maxwell Anderson, S. N. Behrman, Gore Vidal, and Christopher Fry.

In AD 26, Judah Ben-Hur (Charlton Heston) is a wealthy prince and merchant in Jerusalem, who lives with his mother, Miriam (Martha Scott); his sister, Tirzah (Cathy O'Donnell); their loyal slave, Simonides (Sam Jaffe) and his daughter, Esther (Haya Harareet). Judah's childhood friend, the Roman citizen Messala (Stephen Boyd), is now a tribune. After several years away from Jerusalem, Messala returns as the new commander of the Roman garrison. Messala believes in the glory of Rome and its imperial power, while Judah is devoted to his faith and the freedom of the Jewish people. This difference causes tension between the friends and drives the subsequent plot development.
