Bowles hated being grouped in with the beat writers. He had moved to Tangier in 1947, Burroughs didn't arrive until 1953. Burroughs visited socially with Bowles, but even he was 5 years younger than Bowles, and in turn 15 years younger than Ginsberg. Bowles just identified with another earlier generation of writers, like Camus and Sarte. If you have read their works you may find that his use of language spans both camps. The Sheltering Sky was his first novel, published in 1949. The below is a poetic 4-part sentence strung together almost like a quatrain.
"The dark dream would be shattered; the light of terror would be constant; a merciless beam would be turned upon her; the pain would be unendurable and endless."
