The Gospel According to Mark does not name its author. A tradition evident in the 2nd century ascribes it to Mark the Evangelist (also known as John Mark), the companion of Peter, on whose memories it is supposedly based. However, according to the majority view the author is unknown, the author's use of varied sources telling against the traditional account. The gospel was written in Greek, probably around AD 60-70, possibly in Syria.
According to Papias of Hierapolis, writing in the early 2nd century, this gospel was by "Mark, (who) having become the interpreter of Peter, wrote down accurately, though not in order, whatsoever he remembered of the things said or done by Christ." Other early writers such as Irenaeus agree with this. "No early church tradition and no church father ascribes the Gospel to anyone other than Mark." Some modern scholars believe that the gospel was written in Syria by an unknown Christian no earlier than AD 70, using various sources including a passion narrative (probably written), collections of miracles stories (oral or written), apocalyptic traditions (probably written), and disputations and didactic sayings (some possibly written). Some of the material in Mark, however, goes back a very long way, representing an important source for historical information about Jesus.
Mark wrote primarily for an audience of gentile Greek-speaking residents of the Roman Empire: Jewish traditions are explained, clearly for the benefit of non-Jews (e.g. Mark 7:1–4; 14:12; 15:42), and Aramaic words and phrases are expanded upon by the author, e.g. ταλιθα κουμ (talitha koum, Mark 5:41); κορβαν (Corban, Mark 7:11); αββα (abba, Mark 14:36). When Mark makes use of the Old Testament he does so in the form in which it had been translated into Greek, the Septuagint, for instance Mark 1:2; 2:23–28; 10:48b; 12:18–27; also compare 2:10 with Daniel 7:13–14.
