Gunkel Hermann Gunkel 
Folktale in the Old Testament [PDF ebook] 

Gunkel’s classic work of 1917 is a systematic investigation of the Old Testament in the light of the then emerging principles of folktale scholarship; he makes use, for example, not only of the contributions of the Grimm brothers but is aware of the research into classifications of tale types represented by the ground-breaking work of A. Aarne in 1910 and subsequently.
