H.J. Holtzmann's Die synoptischen Evangelien(1863) is not only regarded as having established Markan priority and the basic contours of the Two Source hypothesis; it also offered a sketch of the life of Jesus based on a Mark-like source that represents a starting point for the so-called ‘Liberal Lives of Jesus’ which prevailed from 1863 until the early 1900s. Holtzmann's ‘Life’ portrayed Jesus as an exemplary personality, and posited psychological development in seven stages in the career of Jesus. This essay discusses the intellectual context leading to Holtzmann's book and then offers an annotated English translation of Holtzmann's ‘Life of Jesus’. This is Part 1 of a two-part essay.
