According to many critics of Puerto Rican literature, the great foursome of mid-twentieth-century Puerto Rican poetry is composed by Evaristo Ribera Chevremont, Luis Llorens Torres, Luis Palés Matos, and Julia de Burgos. Ribera Chevremont is also considered to be one of the greatest poets of the Antilles, and mid-twentieth century critics such as Federico de Onís and Concha Meléndez even considered him as one of the most important poets of the Spanish language. Ribera Chevremont traveled to Spain several times and established friendly ties with several writers' circles. He was much admired for his prolific poetic gift, and several of his works were published in that country, as well as in Puerto Rico. He mastered several modern poetic techniques, such as Hispanoamerican Modernism, European “Ultraismo” and "Suprarrealismo". He wrote in free verse as well as in traditional forms, specifically, sonnets, which he mastered fully, as seen in Sonetos del Mar, del Amor, de la Soledad, de la Muerte, de Dios, among others. His last book to reach the public, Sonetos a Galicia, a book dedicated to the land of his father, was published posthumously in 1994 by the poet's widow, María Luisa Méndez de Chevremont and his daughter Iris Ribera-Chevremont Méndez, through the Xunta de Galicia in Spain.

Ribera Chevremont published his first volume of verse, Desfile Romántico, in 1914 at the age of eighteen. In 1974, the poet published El Caos de los Sueños, a book of poems in free verse of a profound, lyrical and universal nature. In 1980, the University of Puerto Rico Press published a complete anthology of his poems in two large volumes, Evaristo Ribera Chevremont: Obra poetica Vol I & II. Besides that comprehensive collection, several poetry books have been posthumously published, such as Jinetes de la inmortalidad, El Libro de las Apologías, and Sonetos a Galicia.
