Risky

Following the encouraging response to my poetry thread, here's another question:-

How come there are next to no seriously good works of art in the fields of, for example:-

Painting,
Sculpture,
Music,
Poetry,
Architecture,
Drama,

that have been created by women?

I accept that some women seem to have got the hang of the novel, and much pleasure have they given me. But otherwise, they are all second-raters, aren't they?
