For Ancient Beliefs, Muses were Spirits.
They were related to Arts, their Patronesses.
When special inspirations were coming after a contact or a relationship with a special woman, she was then named a Muse.
Dante Alighieri had Beatrice Portinari for example, Crowley had His Scarlet Women, W.B. Yeats had His wife, Dante Gabriel Rossetti His model etc. In the East they are called Shaktis, of a certain kind.
From the respect of feminine powers came a better humanity and wonderful expressions of human geniuses…
Respect and love for all Muses then…
Gabriel de Cool, Poet and Muse
