context_page_description: Johann Geiler von Kaysersberg was a priest, considered one of the greatest of the popular preachers of the 15th century.
context_section_description: Among the many volumes published under his name only two appear to have had the benefit of his revision, namely, Der Seelen Paradies von waren und volkumen Tugenden, and that entitled Das irrig Schaf. Of the rest, probably the best-known is a series of lectures on his friend Sebastian Brant's work, Das Narrenschiff or the Navicula or Speculum fatuorum, of which an edition was published at Strasbourg in 1511 under the following title: Navicula sive speculum fatuorum praestantissimi sacrarumliterarum doctoris Joannis Geiler Keysersbergii.
  The numerous volumes of Geiler's sermons and writings which have been published do not give a complete picture of the characteristic qualities of the preacher. An orator, Geiler sought, without regard to other considerations, was to produce the most powerful effect on his hearers. He prepared himself with great care for the pulpit, writing out his sermons beforehand, as his contemporary Beatus Rhenanus reports; those preparatory compositions were drawn up not in German, but in Latin.
  Only a very small part of the sermons that have been issued under his name are directly his. At a very early date his addresses were taken down by others and published. The best critic of Geiler's works, E. Martin of Strasbourg, attempted, in the Allgemeine deutsche Biographie, to give a summary of Geiler's genuine writings; according to him the authenticated writings number thirty-five.
  It is not certain that any of the extant works give exactly what Geiler said. It is evident from them that the Strasbourg preacher was widely read, not only in theology, but also in the secular literature of the day. This is shown by the sermons having Sebastian Brant's Ship of Fools, which appeared in 1494, for their theme; these sermons attained the greatest popularity. Geiler displayed also facility in using public events to attract and hold the attention of his hearers.
  In originality of speech Geiler is in form, as in time, between Berthold of Ratisbon and Abraham a Sancta Clara. Geiler himself complained bitterly that neither clergy nor laity were willing to join in a common reform. His works are an important source for the history of the civilization of those times. His thoughts were expressed in the language of ordinary life: Geiler's writings are a source for the knowledge of the speech, customs and beliefs of the common people at the beginning of the sixteenth century.
