John Mark, later known simply as Mark, was a Jew by birth. He was the son of that Mary who was proprietress of the Cenacle or "upper room" which served as the meeting place for the first Christians in Jerusalem (Acts 12:12). He was still a youth at the time of the Savior's death. In his description of the young man who was present when Jesus was seized and who fled from the rabble leaving behind his "linen cloth," the second Evangelist might possibly have stamped the mark of his own identity.Hat Tip: A Catholic View
During the years that followed, the rapidly maturing youth witnessed the growth of the infant Church in his mother's Upper Room and became acquainted with its traditions. This knowledge he put to excellent use when compiling his Gospel. Later, we find Mark acting as a companion to his cousin Barnabas and Saul on their return journey to Antioch and on their first missionary journey. But Mark was too immature for the hardships of this type of work and therefore left them at Perge in Pamphylia to return home.
As the two apostles were preparing for their second missionary journey, Barnabas wanted to take his cousin with him. Paul, however, objected. Thereupon the two cousins undertook a missionary journey to Cyprus. Time healed the strained relations between Paul and Mark, and during the former's first Roman captivity (61-63), Mark rendered Paul valuable service (Col. 4:10; Philem. 24), and the Apostle learned to appreciate him. When in chains the second time Paul requested Mark's presence (2 Tim. 4:11).
An intimate friendship existed between Mark and Peter; he played the role of Peter's companion, disciple, and interpreter. According to the common patristic opinion, Mark was present at Peter's preaching in Rome and wrote his Gospel under the influence of the prince of the apostles. This explains why incidents which involve Peter are described with telling detail (e.g., the great day at Capharnaum, 1:14f)). Little is known of Mark's later life. It is certain that he died a martyr's death as bishop of Alexandria in Egypt. His relics were transferred from Alexandria to Venice, where a worthy tomb was erected in St. Mark's Cathedral.
The Gospel of St. Mark, the shortest of the four, is, above all, a Roman Gospel. It originated in Rome and is addressed to Roman, or shall we say, to Western Christianity. Another high merit is its chronological presentation of the life of Christ. For we should be deeply interested in the historical sequence of the events in our blessed Savior's life.
Furthermore, Mark was a skilled painter of word pictures. With one stroke he frequently enhances a familiar scene, shedding upon it new light. His Gospel is the "Gospel of Peter," for he wrote it under the direction and with the aid of the prince of the apostles. "The Evangelist Mark is represented as a lion because he begins his Gospel in the wilderness, `The voice of one crying in the desert: Make ready the way of the Lord,' or because he presents the Lord as the unconquered King."

Most of what we know about Mark comes directly from the New Testament. He is usually identified with the Mark of Acts 12:12. (When Peter escaped from prison, he went to the home of Mark's mother.)
Paul and Barnabas took him along on the first missionary journey, but for some reason Mark returned alone to Jerusalem. It is evident, from Paul's refusal to let Mark accompany him on the second journey despite Barnabas's insistence, that Mark had displeased Paul. Later, Paul asks Mark to visit him in prison so we may assume the trouble did not last long.
The oldest and the shortest of the four Gospels, the Gospel of Mark emphasizes Jesus' rejection by humanity while being God's triumphant envoy. Probably written for Gentile converts in Rome—after the death of Peter and Paul sometime between A.D. 60 and 70—Mark's Gospel is the gradual manifestation of a "scandal": a crucified Messiah.
Evidently a friend of Mark (Peter called him "my son"), Peter is only one of the Gospel sources, others being the Church in Jerusalem (Jewish roots) and the Church at Antioch (largely Gentile).
Like one other Gospel writer, Luke, Mark was not one of the 12 apostles. We cannot be certain whether he knew Jesus personally. Some scholars feel that the evangelist is speaking of himself when describing the arrest of Jesus in Gethsemane: "Now a young man followed him wearing nothing but a linen cloth about his body. They seized him, but he left the cloth behind and ran off naked" (Mark 14:51-52).
Others hold Mark to be the first bishop of Alexandria, Egypt. Venice, famous for the Piazza San Marco, claims Mark as its patron saint; the large basilica there is believed to contain his remains.
A winged lion is Mark's symbol. The lion derives from Mark's description of John the Baptist as a "voice of one crying out in the desert" (Mark 1:3), which artists compared to a roaring lion. The wings come from the application of Ezekiel's vision of four winged creatures (Ezekiel, chapter one) to the evangelists.
