|The New Testament mentions Luke briefly a few times, and the Pauline Epistle to the Colossians refers to him as a physician (from Greek for 'one who heals'); thus he is thought to have been both a physician and a disciple of Paul. Since the early years of the faith, Christians have regarded him as a saint. He is believed to have been a martyr, reportedly having been hanged from an olive tree, though some believe otherwise.|

Mark the Evangelist is the traditionally ascribed author of the Gospel of Mark. Mark is said to have founded the Church of Alexandria, one of the most important episcopal sees of early Christianity. His feast day is celebrated on April 25, and his symbol is the winged lion. According to the Coptic tradition, Mark was born in Cyrene, a city in the Pentapolis of North Africa (now Libya). This tradition adds that Mark returned to Pentapolis later in life, after being sent by Paul to Colossae (Colossians 4:10; Philemon 24. Some, however, think these actually refer to Mark the Cousin of Barnabas), and serving with him in Rome (2 Tim 4:11); from Pentapolis he made his way to Alexandria. When Mark returned to Alexandria, the pagans of the city resented his efforts to turn the Alexandrians away from the worship of their traditional gods.In AD 68, they placed a rope around his neck and dragged him through the streets until he was dead.
