In the 'Game of Thrones' universe, Tyrion Lannister is often seen as a wise character. Despite his physical disadvantages, he uses his intelligence and wit to navigate the complex political landscape and make shrewd decisions.
Mercy Watson is the main character, a lovable pig. And of course, her owners are also important characters in the story.
Well, without actually reading the novel, it's hard to say for sure. But likely, the main characters would be the wise women themselves. There could be one or more women who are the central focus of the story, perhaps with different personalities and areas of wisdom.
The main character is Hazel Motes. He's a complex figure, full of contradictions. Another important character is Asa Hawks, who is a sort of false prophet. Then there's Sabbath Lily Hawks, who has her own motives and is involved in the strange relationships in the story.
Based on the title, it seems that Brown and Watson are likely to be the main characters.
There are the four wise men, of course. Each of them has their own characteristics. And there might be other characters that they meet during their journeys, like the people in the villages they pass through or the ones who offer them shelter or advice along the way.
Obviously, there is the wise old crow. There might also be other animals like the fox which often appears in such fables as a character that tries to trick the crow.
The main characters in the 'little wise hen story' are the little wise hen herself and some other animals. Usually, there are animals like the cat, the dog, and the pig. These other animals are the ones who refuse to help the hen with her work.
Since I don't know the exact 'the wise girl story', it's difficult to say. But surely the wise girl herself is a main character. There could also be her family members, like her parents or siblings, or perhaps friends or a mentor who helps her develop her wisdom.
I don't know for sure without reading the story. But I would assume the 'wise children' are the main characters.
There are the fourth wise man himself, and presumably there were other people he met along his journey like the sick, the poor, and the oppressed. And of course, the other three wise men are also part of the story's context.
