Swiss writer and Dominican monk, whose collection of fables in verse was the first book to be printed in the German language (Bamberg, 1461).

Boner, known to have been of a Bernese family, is mentioned in records between 1324 and 1349. He compiled and translated his collection of fables for Johann von Ringgenberg, his Bernese patron. Known as bîschaft or bîspel (“examples”), each of the tales emphasizes a moral. Written in Middle High German, the collection was probably completed in about 1350 and is titled Der Edelstein (“The Precious Stone”), because precious stones were said to cast a spell, and Boner hoped that his tales would do the same. Although he named only two of his sources— Aesop's Fables and the fables of Flavius Avianus (a 4th-century Latin writer)—he may have drawn on other material. Many manuscripts of the collection existed; its having been one of the first manuscripts to be printed in German is evidence of its popularity.
