David Strauss (1808–1874), at the age of 27 years, pioneered the search for the "Historical Jesus" by rejecting all supernatural events as mythical elaborations. His 1835 work, "Life of Jesus", was one of the first and most influential systematic analyses of the life story of Jesus, aiming to base it on unbiased historical research. Strauss viewed the miraculous accounts of Jesus' life in the gospels in terms of myths which had arisen as a result of the community's imagination as it retold stories and represented natural events as miracles. Albert Schweitzer wrote in "The Quest of the Historical Jesus" (1906; 1910) that Strauss's arguments "filled in the death-certificates of a whole series of explanations which, at first sight, have all the air of being alive, but are not really so". He added that there are two broad periods of academic research in the quest for the historical Jesus, namely, "the period before David Strauss and the period after David Strauss". Among the works that appeared after Strauss, Ernest Renan's book "Vie de Jesus", which combined scholarship with sentimental and novelistic psychological interpretation, was very successful and had eight re-printings in three months. Renan merged gospel narratives with his own psychological interpretations, e.g. that Jesus preached a "sweet theology of love" in Galilee, but turned into a revolutionary once he encountered the establishment in Jerusalem.
