Mark the Deacon (Latin: Marcus Diaconus) was a monk in the Egyptian desert of Scetes who became the biographer of Saint Porphyrius in the 5th century. He was, at a later date, made deacon of his church. To effect the sale of the property still owned by Porphyrius in his native city, Mark set out for Thessalonica and, upon his return, the proceeds were distributed among the monasteries of Egypt and among the necessitous in and around Jerusalem. His masterpiece, the "Vita S. Porphyrii" ("Life of St. Porphyrius), formerly known only in a Latin translation, was published in 1874 by M. Haupt in its original Greek text. A new edition was issued in 1895 by the Bonn Philological Society.

Avon Barksdale was the head of the Barksdale organization in season one. He comes from the projects, lives in the projects and plans to stay in the projects. For most of season 1 he is the target of a homicide detective Jimmy McNulty who seems to be the only authoritative figure aware of his presence or his empire that spans the most sought after territory in Baltimore for drug dealers. Avon is uniformly feared by all other drug dealing criminal organizations in Baltimore due to his ferocity but due to his 'West Side' mentality is no threat to 'East Side' gangs. Together with his closest friend Russell "Stringer" Bell, Avon and their enforcers hold a monopoly on the drug trade in West Baltimore through intimidation and murder.
