During the Renaissance, use of the term diverged to refer to gnostic knowledge that offers the individual enlightenment and salvation through a knowledge of the bonds that are believed to unite her or him to the world of divine or intermediary spirits. Christian theosophy arose in Germany in the 16th century. Inspired to a considerable extent by the works of Paracelsus (1493–1541). The term had not yet reached a settled meaning, however, as the mid-16th century "Theosophia" by Johannes Arboreus provided a lengthy exposition that included no mention of esotericism.
