For a number of reasons, Motion's prose memoir far transcends the television version, compelling as that was. As poet-novelist, Motion is primarily a writer, and a highly self-examining one. Indeed one of his most affecting works was the prose memoir of his mother's death in Poetry Review (there are strikingly parallel synergic family memoirs by Michael Longley and Craig Raine). In Motion's Keats voyage we become progressively more distanced from the dying Keats, at least in any way we might have anticipated finding him. Certainly some of the Keats quotations express the book's centre: "Is there another life? Shall I awake and find all this a dream? There must be - we cannot be created for this sort of suffering." And at the end: "O what an account I could give you of the Bay of Naples if I could once more feel myself a Citizen of this world." But Motion can make a Dantesque return to this world, denied to Keats: a distinction of absolute importance.
An early poem of Motion's begins "It was straight out of Conrad but true." The strange strength of this magnificent brief memoir - it takes 54 pages - is that a journey which is described with such unportentous graphicness can also be a progress in imaginative self-abnegation. Art concealing art indeed! For an example of the unportentous, Motion in a fit of deep gloom (characteristically described with neither self-pity nor self-accusation) is greeted by one of the crew who "belches vilely" and cheerfully remarks "Wind!"; the author comments laconically, "I want to stick a marlin spike up his arse and throw him to the shark which has just idled past, its fin slick and alert." Hardly a mystical reflection; yet the Conradian theme traces the highly interior progress of the mystic's visionary boredom. "At some stages it occurs to me that I've never been so bored in my life. But I don't want to be anywhere else, doing anything else. My boredom isn't painful - it's like a trance, a rapture."
This is not the book's conclusion. The dying Keats, alas, was not able to become again a Citizen of the World. Salt Water ends with troubled Conradian awkwardness in the modern poet's attempt to chafe himself back into life. And of course once the lesson that "my life need not always be the one I am living" has been learnt, the book entirely supports a re-entry into life.
Motion's exhilarating gift for tactile description has an integrity which exposes the meretriciousness of such things as Golding's Conradian pastiches. This strength is as much in evidence in the poems as in the memoir, and there is an extraordinarily sustained web of reference across the two forms which contributes to the book's coherence: the tragic merman is echoed both in the young shark thrown back into the sea, and in the crab, "pale green, which lay on its back wriggling, then got booted over the side. What did it think had happened to it, snatched from its mid-Biscay existence for a moment? A glimpse of the afterlife." No prevaricating question mark at the end, notice. The book is full of such passages of dry, elegant, original ordinariness. There are other recurrences: Motion chafes his way back into emotional life, in a haunting paradox, by spending the two hours of a bus journey reliving the pain of his mother's death. But she is also in the body of the book in the harsh materialist tragedy of "The Spoilt Child", and in her brusque dismissal of any attempt to dramatise her death in "Dead March": "I wasn't 'whisked away': I broke my skull."
This conclusively illustrates Motion's greatest and most distinctive gift, which is to look squarely at the world and describe it with a plain and unsentimental eloquence that makes worldly value seem all the more unquestionable. The more you read this book, the more clearly it emerges as a rare masterpiece of feeling and sensual evocation. Perhaps after all this is Keats for our age.
