The difference is the perspective, the rest I will leave to you.
The symbol in the excerpt <em>is the new cloak. </em>
Symbols in literature are used to signify ideas through them, which means that the author can use a symbol with the purpose of giving them symbolic meanings that in fact are completely different from the literal sense. For example, in our daily life, we can say that a white pigeon is a symbol of peace or that the color red is a symbol of love.
Since the excerpt is from the Odyssey, I can deduce that the new cloak represents Odysseus’s change from an exhausted traveler to the returning hero.
The author can show the character development
in many different ways. One of which is that the author must research about the
character's basic facts. For instance, if the character is a doctor, the writer must
read books related books, interview doctors etc. This method will also lead the
author to establish a well-written history of the character. The author must be
creative and make his character like a living person.
