I like Patti Smith's lyrics, and sometimes think I could be influenced by them. But she has a kind of cool that's beyond me.

When I was 16, I was taught by a wonderful teacher who let me ignore the Greek syllabus and just read Homer.

If you put a real leaf and a silk leaf side by side, you'll see something of the difference between Homer's poetry and anyone else's. There seem to be real leaves still alive in the 'Iliad,' real animals, real people, real light attending everything.

I think it's often assumed that the role of poetry is to comfort, but for me, poetry is the great unsettler. It questions the established order of the mind. It is radical, by which I don't mean that it is either leftwing or rightwing, but that it works at the roots of thinking.

Stripped of its plot, the 'Iliad' is a scattering of names and biographies of ordinary soldiers: men who trip over their shields, lose their courage or miss their wives. In addition to these, there is a cast of anonymous people: the farmers, walkers, mothers, neighbours who inhabit its similes.
