Book excerpt: Drawing on the early correspondence of Martin Luther, Timothy Dost presents a reassessment of the degree to which humanism influenced the thinking of this key reformation figure. Studying letters written by Luther between 1507 and 1522, he explores the various ways Luther used humanism and humanist techniques in his writings and the effect of these influences on his developing religious beliefs. The letters used in this study, many of which have never before been translated into English, focus on Luther's thoughts, attitudes and application of humanism, uncovering the extent to which he used humanist devices to develop his understanding of the gospel. Although there have been other studies of Luther and humanism, few have been grounded in such a close philological examination of Luther's writings. Combining a sound knowledge of recent historiography with a detailed familiarity with Luther's correspondence, Dost provides a sophisticated contribution to the field of reformation studies.
