I was thinking Milton and Homer deserved to be included. I read a page of Homer just yesterday, it's the first thing in my copy of Between a Rock and a Hard Place, the Aron Ralston account of his desert odyssey. Blake refers to Milton as one of the "true poets," an interesting concept. Blake regarded some famous artists as virtual imposters, I think.Nobody mentioned Dante Alighieri or Homer yet? FFS...
Not to mention, John Milton.
