Writer’s “Voice” and Writer’s “Muse”: Why is the explanation of Writer’s Genius—but not other kinds of genius—often Personified?

In Greek mythology, there are Muses for all kinds of arts and sciences. And geniuses outside of literature often do talk of the importance of inspiration and imagination.

But do Thomas Edison, Albert Einstein, and most other non-literary geniuses attribute their creativity to anything as personified as “voice” or “muse”? Most don’t. (Any that do invoke “voice” or “muse” may have the same explanation as literary geniuses.)

So why is literary genius often explained, in part, by something as personified as “voice” or “muse”?
