W. H. Auden made it clear in his ‘Letter to Lord Byron’ and various prose writings on Byron that what counted for him was the poet’s ‘voice’: ‘I like your muse because she’s gay and witty / […] / I like her voice that does not make me jump’.1 ‘Voice’ was no small matter for Auden, since as he famously declared in ‘September 1, 1939’ it was all he had ‘[t]o undo the folded lie’.2 Addressing Byron in the form of a verse-letter allowed him to find a new voice for himself. Within the context of Letters from Iceland, the format permitted him to talk on public matters while adopting the tone of a private communication; and, in addition, it allowed him to develop a broader conception of poetry’s scope, by finding in it a place for the non-earnest – something, as he saw it, that had been lost along the way in the development of poetry since Byron’s time. It gave a new direction to his own writing, preparing the way for the longer poems of the second half of his career.
