The biblical scholar Johann David Michaelis (1717–1791) advocated the use of other Semitic languages in addition to Hebrew to understand the Old Testament, and in 1750, wrote the first modern critical introduction to the New Testament. Instead of interpreting the Bible historically, Johann Gottfried Eichhorn (1752–1827), Johann Philipp Gabler (1753–1826), and Georg Lorenz Bauer (1755–1806) used the concept of myth as a tool for interpreting the Bible. Rudolf Bultmann later used this approach, and it became particularly influential in the early twentieth century.
