Textual criticism (or lower criticism) is a branch of literary criticism that is concerned with the identification and removal of transcription errors in the texts of manuscripts. Ancient scribes made errors or alterations when copying manuscripts by hand. Given a manuscript copy, several or many copies, but not the original document, the textual critic seeks to reconstruct the original text (the archetype or autograph) as closely as possible. The same processes can be used to attempt to reconstruct intermediate editions, or recensions, of a document's transcription history. The ultimate objective of the textual critic's work is the production of a "critical edition" containing a text most closely approximating the original.

There are three fundamental approaches to textual criticism: eclecticism, stemmatics, and copy-text editing. Techniques from the biological discipline of cladistics are currently also being used to determine the relationships between manuscripts.

The phrase lower criticism is used to describe the contrast between textual criticism and "higher" criticism, which is the endeavor to establish the authorship, date, and place of composition of the original text.

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.
