Question: Who is credited with presiding over the transition of childrens literature from parables to works that appealed to imagination and emotion?

full_context: Document 1: Aesop: Aesop ( ; Ancient Greek: Αἴσωπος , "Aisōpos "; c. 620 – 564 BCE) was a Greek fabulist and story teller credited with a number of fables now collectively known as "Aesop's Fables".

Many of the tales are characterized by animals and inanimate objects that speak, solve problems, and generally have human characteristics.

Document 4: Religious symbolism: Religious symbolism provides an additional means to communicate the underlying message of a religion via symbols, apart from communication by words. Jesus in Mathew 13:13 says, "The reason I use parables in talking to them is that they look, but do not see, and they listen, but do not hear or understand." Symbolism, like parables, clarifies a message to make its meaning more accessible to the mind. It is the use of symbols, including archetypes, acts, artwork, events, or natural phenomena, by a religion. Religions view religious texts, rituals, and works of art as symbols of compelling ideas or ideals.

Document 11: Cautionary tale: A cautionary tale is a tale told in folklore, to warn its hearer of a danger. There are three essential parts to a cautionary tale, though they can be introduced in a large variety of ways. First, a taboo or prohibition is stated: some act, location, or thing is said to be dangerous. Then, the narrative itself is told: someone disregarded the warning and performed the forbidden act. Finally, the violator comes to an unpleasant fate, which is frequently related in expansive and grisly detail.

Document 14: Jewish folklore: Jewish folklore are legends, music, oral history, proverbs, jokes, popular beliefs, fairy tales, stories, tall tales, and customs that are the traditions of Judaism. Folktales are characterized by the presence of unusual personages (dwarfs, giants, fairies, ghosts, etc.), by the sudden transformation of men into beasts and vice versa, or by other unnatural incidents (flying horses, a hundred years' sleep, and the like). A number of haggadic stories bear folktale characteristics, especially those relating to Og, King of Bashan, which have the same exaggerations as have the "lügenmärchen" of modern German folktales. There are signs that a certain number of fables were adopted by the Rabbis either from Greek or, indirectly, from Persian and Indian sources.
