The Muses?

I think that I found the 9 Muses in "The Skin of Our Teeth." I'm not sure but the passage is on page 38 and reads "Up in town there are nine sisters. There are three or four of them here. They're sort of music teachers-- and one of them recites and one of them--" In case anyone is curious, here is a link to the 9 Muses and what they represent.
