Calypso

You are a goddess, eternally young.

A very beautiful nymph, who is a goddess. She has eternal life, so she's forever young.

Calypso would probably be a protagonist. Though she's not the main character of the story, she isn't against the main character either.

Calypso has external struggles. She struggles with letting Odysseus leave. He has to leave because he wants to return home to his wife.

Beautiful- You are a goddess, eternally young

Selfish- She doesn't want Odysseus to return home to his wife.

Egoistic- I don't mind saying she's not my equal in beauty, no matter how you measure it. Mortal beauty cannot compare with immortal.

Calypso is a static character because she remains the same throughout the story.
