As artists get older, they are supposed to mature, and commentators begin to look for the demarcations of their three periods, a nice bequest from Beethoven. One vitiating side effect of this is to misplace freshness in their art. Judging the vital middle period works, and bowing before the sublimity of the late, the critic bestows a nostalgic glance over his shoulder to the early output – ah, what freshness, what morning glory there! It may be true of Beethoven, but the experience of most of us lesser creatures is more often the opposite. We start a bit grey and elderly: only later, after much experience, do we throw off ponderousness, embrace wit and light-spiritedness and appear verdant for the public gaze. I hope Chris Wallace-Crabbe will not object to my including him in this (to me) honourable company: those who write, after thirty years on the job, with twice the élan they had at the beginning.

I have sat on these books longer than is reasonable for a review, yet have to confess that I am not satisfied with the readiness of what follows. I got the Porter first, but receiving the Johnston thought that they in some ways offered similar difficulties, perhaps similar rewards, to the reader, and that it might be neat to review them together.

It is a brave thing to publish your Collected Poems in your early fifties, braver when you are an Australian resident in England publishing there, and a loading might be put on for additional hazard when, like Peter Porter, you are poetry editor both for Oxford and for The Observer. For, when it comes to Collected Poems, it is your very influence that makes you vulnerable.
