The name of the Muse of Writing, according to the ancient Greeks, was Calliope. Actually, she was the muse of heroic and epic poetry. Since I write historical fiction, I think that's about as close as I come.
I've been going hammer and tongs at a new project, and she has been with me every step of the way. ...or do I mean that she has obstructed me? Hm. Perhaps that is a better choice of words...
The hard thing is that if you do write, you have to have a muse.
...but do I have to have one that sits on my keyboard?
Now all I need is Terpsichore (muse of dance) to tap-dance on my keyboard. I suspect it's only a matter of time.
