The Apostle and Evangelist Mark (also called John Mark) is the author of the Gospel of Mark. According to Church tradition, he was the young man who was seized by soldiers in the Garden of Gethsemane and fled away naked (Mark 14:51-52). He was a companion of the Apostles Peter, Paul, and Barnabas his uncle. After the death of Peter, Mark traveled to Egypt and established the Church of Alexandria, baptizing many pagans and ordaining clergy to lead the people.
In the year 63, he was seized while serving the Divine Liturgy, dragged through the streets, and imprisoned. He was killed the following day, and when the pagans went to cremate his body, there was a violent earthquake. The Christians then took his body and gave him a proper Christian burial. A church was built on the site, but when the Moslems took control of Egypt, his relics were transferred to Venice.
His feast is universally celebrated on April 25, and again on January 4 with the Seventy Apostles. In the Church's iconographic tradition, he is sometimes represented by a lion after Ezekiel's vision of four creatures, which represent the four Evangelists.
