"When I was 16, I was taught by a wonderful teacher who let me ignore the Greek syllabus and just rea..." — Alice Oswald

At eight, I made a commitment to poetry. Until then, I thought I'd be a policeman. But I went a whole night without sleeping, and the next day the world had changed. It needed a different language.

One of the rules of Greek lament poetry is that it mustn't mention the dead by name in case of invoking a ghost. Maybe the 'Iliad,' crowded with names, is more than a poem. Maybe it's a dangerous piece of the brightness of both this world and the next.

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.
