Philip Hoare at The New Statesman:
Was Billy Budd, the Handsome Sailor at the heart of the book, black? Scholars such as John Bryant believe that there is internal evidence in the manuscript of the book – found in a bread tin after Melville’s death in 1891 and not published until 1924 – that the author had played with the idea of making his hero a man of African heritage. Billy is loved by all the crew and is described as blond and blue-eyed later in the story. Yet the sensuous descriptions of the Liverpool sailor and the Greenwich veteran elide to create a counterfactual version in which Billy becomes a black star at the centre of his constellation of shipmates.
Indeed, some critics – most notably, Cassandra Pybus at the University of Sydney – have suggested that another 19th-century anti-hero was a person of colour. In Wuthering Heights, published in 1847, two years before Melville’s visit, Heathcliff is described as a “regular black”, an orphan found in the Liverpool docks – an intriguing notion explored in Andrea Arnold’s brilliant 2011 film adaptation.
Melville witnessed great changes in the fortunes of black Americans. Moby-Dick is an allegory of the struggle against slavery in the run-up to the American Civil War; the Melville scholar Robert K Wallace believes that the writer heard the fugitive slave-turned-emancipationist Frederick Douglass speak in the 1840s and that they may have even met.
