Answer:
The best answer to the question: How is an allegory different from a myth, would be: A: An allegory includes characters that represent moral and ethical qualities, while a myth provides explanation of elements in a culture.
Explanation:
An allegory is technically a literary device, most like a metaphor, whose intention is to present, through symbolism, deeper meanings and concepts that cannot be understood better unless these symbols are used. Maybe one area in which allegory is in religion, where texts are written in such a way that they come out full of symbolisms that represent concepts and ideas that are too deep and too broad to understand using any other means. Usually, allegories will have as a characteristic, characters that become the very representation of the moral and ethical values of a society. Myths, on the other hand, though they may use allegorical techniques, they are, essentially, narratives or stories that represent not only the underlying beliefs of a society regarding their oirigins, but also the justification for their cultural traditions and customs. This is why the best answer from all the ones here, is A.
