Joseph, the dream interpreter.

Explanation:

The Alchemist's  book is a novel by Paulo Coelho. This novel got a good reception by  the public but it had bad critics and deeping analysis due to the sentences or parallelism in some texts with texts of the bible.

In fact some preachers have commented as introduction of theirs sermons.

(This is a another subject to discuss).  

Certainly the comments of the old man ( center of chieftains) for Santiago ( The young pastor) was about a man who believed in dreams and was sold as slave (For inference this is Joseph the son of Jacob).

- "d.)  describe the iroquois belief of how the earth was created. for the iroquois, there was no reason to explain the importance of rituals. also, as animists, they didn't need a special elaboration as to why animals are important or why they had a crucial role in the earth's creation. this is just an authentic myth that explains the creation of the earth. every culture has produced creation myths."
