Some curious uses of "the"

Posted by Sphinx on January 14, 2004

Why there are "the"s here?
1.Dolly the sheep
2.Alexander the Great
Do you have other examples of this kind?

3.In "Rain Music", there is a sentence saying:
"His soft, black curls rest against the white of the pillow..."
"the white of the pillow?" Why not use "the white pillow"?
