In Greek Mythology, a Muse was any of the nine daughters of Zeus & Mnemosyne. Each one a guardian of a different art or science. Their names are Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, and Urania. I am not sure which is the guardian for a novelist, but I will take whoever wants the job. I need all the help I can get.
A Muse can also be any guiding spirit or source of inspiration. For my first book, believe it or not, my Muse were two tattoo’s I had gotten on my arms to represent my son and daughter. They were a Dragon and a Faerie, and as soon as I decided on those images, it was like the flood gates were opened and the story poured forth.
People will say that’s just being superstitious, but I believe in it. I’m still waiting for the Muse on my current book. I will try and seek it out, but I know in the end, it will be my Muse that finds me.
