Early tradition says Mark wrote in Italy5and in Rome.6
This external testimony finds support in the internal evidence of the Gospel itself. Many indications in the text point to Mark's having written for Gentile readers originally, particularly Romans. He explained Jewish customs that would have been strange to Gentile readers (e.g., 7:2-4; 15:42). He translated Aramaic words that would have been unfamiliar to Gentiles (3:17; 5:41; 7:11, 34; 15:22). Compared to Matthew and Luke he used many Latinisms and Latin loan words indicating Roman influence. He showed special interest in persecution and martyrdom that would have been of special interest to Roman readers when he wrote (e.g., 8:34-38; 13:9-13). Christians were suffering persecution in Rome and throughout the empire then. Finally the early circulation and widespread acceptance of this Gospel among Christians suggest that it originated from and went to a powerful and influential church.7
