Mariano Brull Caballero (February 24, 1891 – June 8, 1956) was a Cuban poet usually associated with the French Symbolist movement. Two Symbolists who strongly influenced him were Stéphane Mallarmé and Paul Valéry. Among Cuban poets of the first half of the 20th century he was the most outstanding of those who wrote poetry for poetry's sake, as opposed to poetry that addressed social issues or poetry that was inspired by the culture of Cubans of African descent. Because of his interest in the sounds of words, he is known for a type of poetry called "jitanjáfora" in which the words are virtually meaningless, their sounds all-important. A diplomat by profession, he lived many years in various countries of Europe and the Americas.
