Longinus is the name given in medieval and some modern Christian traditions to the Roman soldier who pierced Jesus in his side with a lance, the "Holy Lance" (lancea, in the Latin Vulgate) while he was on the Cross. The figure is unnamed in the gospels. The Longinus legend further identifies this soldier as the centurion present at the Crucifixion, who testified, "In truth this man was son of God." Longinus' legend grew over the years to the point that he was said to have converted to Christianity after the Crucifixion, and he is traditionally venerated as a saint in the Catholic Church, Eastern Orthodox Church, and several other Christian communions.

No name for this soldier is given in the Gospels; the name Longinus is found in the pseudepigraphal Gospel of Nicodemus that was appended to the apocryphal Acts of Pilate. Longinus did not start out as a saint. An early tradition, found in the 4th-century pseudepigraphal "Letter of Herod to Pilate," claims that Longinus suffered for having pierced Jesus, and that he was condemned to a cave where every night a lion came and mauled him until dawn, after which his body healed back to normal, in a pattern that would repeat till the end of time. Later traditions turned him into a Christian convert, but as Sabine Baring-Gould observed, "The name of Longinus was not known to the Greeks previous to the patriarch Germanus, in 715. It was introduced amongst the Westerns from the Apocryphal Gospel of Nicodemus. There is no reliable authority for the Acts and martyrdom of this saint." However, there is an old tradition linking the birthplace of Longinus with the small village of Lanciano, Samnite territory, in today's Abruzzo region of Central Italy.

The Greek is a fictional character on the HBO drama The Wire, played by actor Bill Raymond. The Greek is the head of an international criminal organization involved in narcotics and human trafficking. The Greek is a mysterious figure involved in numerous criminal activities. His given name is never mentioned on the show, and though he is known only as "The Greek", he has stated (in the episode Port in a Storm) that he is not actually Greek. A quiet and unassuming man, the Greek prefers to keep a low profile, operating all of his business through his lieutenant Spiros "Vondas" Vondopoulos. His smuggling organization operated from a small diner in Baltimore for years, and while Vondas would conduct business the Greek would listen in quietly at the counter. Nick Sobotka, upon seeing the Greek identify himself, was amazed that the shadowy figure had been in plain sight the entire time.

Despite his calm appearance, the Greek is cunning and ruthless, and only interested in facts that make him more money. Series creator David Simon has said that The Greek is an embodiment of raw unencumbered capitalism. Anyone interfering in this process is eliminated immediately, and he prefers to leave victims headless and handless to hinder identification.
