Gospel According to Mark, 1 in the Bible Encyclopedia - ISBE

II. Contents and General Characteristics. 1. Scope: The Gospel begins with the ministry of John the Baptist and ends with the announcement of the Resurrection, if the last 12 verses be not included. These add post-resurrection appearances, the Commission, the Ascension, and a brief summary of apostolic activity. Thus its limits correspond closely with those indicated by Peter in Acts 10:37-43. Nothing is said of the early Judean ministry. The Galilean ministry and Passion Week with the transition from the one to the other (in Acts 10) practically make up the Gospel. 2. Material Peculiar to Mark: Matter peculiar to Mark is found in 4:26-29 (the seed growing secretly); 3:21 (his kindred's fear); 7:32-37 (the deaf and dumb man); 8:22-26 (the blind man); 13:33-37 (the householder and the exhortation to watch); 14:51 (the young man who escaped). But, in addition to this, there are many vivid word-touches with which the common material is lighted up, and in not a few of the common incidents Mark's account is very much fuller; e.g. 6:14-29 (death of John the Baptist); Mk 7:1-23 (on eating with unwashen hands); 9:14-29 (the demoniac boy); 12:28-34 (the questioning scribe). There is enough of this material to show clearly that the author could not have been wholly dependent on the other evangelists. Hawkins reckons the whole amount of peculiar material at about fifty verses (Hor. Syn., 11)...
