He had first attracted attention on St. Lucia with a book of poems that he published himself as a teenager. Early on, he showed a remarkable ear for the music of English — heard in the poets whose work he absorbed in his Anglocentric education and on the lips of his fellow St. Lucians — and a painter’s eye for the particulars of the local landscape: its beaches and clouds; its turtles, crabs and tropical fish; the sparkling expanse of the Caribbean.

In the poem “Islands,” from the collection “In a Green Night,” he wrote:

I seek,

As climate seeks its style, to write

Verse crisp as sand, clear as sunlight,

Cold as the curled wave, ordinary

As a tumbler of island water.

He told The Economist in 1990: “The sea is always present. It’s always visible. All the roads lead to it. I consider the sound of the sea to be part of my body. And if you say in patois, ‘The boats are coming back,’ the beat of that line, its metrical space, has to do with the sound and rhythm of the sea itself.”

There was nothing shy about Mr. Walcott’s poetic voice. It demanded to be heard, in all its sensuous immediacy and historical complexity.

“I come from a place that likes grandeur; it likes large gestures; it is not inhibited by flourish; it is a rhetorical society; it is a society of physical performance; it is a society of style,” he told The Paris Review in 1985. “I grew up in a place in which if you learned poetry, you shouted it out. Boys would scream it out and perform it and do it and flourish it. If you wanted to approximate that thunder or that power of speech, it couldn’t be done by a little modest voice in which you muttered something to someone else.”
