Some theorists believe Matus was killed by members of the Conservative party in a political hunt after Zelaya's fall, while other, less-accepted theories believe he committed suicide.

While living in California, he discovered North American poetry and became a great admirer of many of its authors, such as Walt Whitman, Edgar Allan Poe, and Ezra Pound, who he would eventually translate into Spanish.

A fan of the burlesque and a man of a refined sense of humour, in his 20th Coronel published in his most sarcastic tone the poem “Ode to Ruben Dario,” in which he publicly established a break from Modernism.

Furthermore, he provided a philosophical and intellectual foundation to the idea of Somoza ruling Nicaragua forever in a public letter that, years later, he regretted and felt ashamed of.

[4] In 1935, he was elected Congressman, appointed Sub Secretary of Education (Instrucción Pública) in 1938, and Cultural Attache in New York and Spain in 1948 by President Roman Reyes, Somoza's uncle.

He remained retired and writing, only linked to intellectual activities with sporadic visits to the capital cities of Managua, Nicaragua, and San Jose, Costa Rica.

In July 1960, he was among the intellectuals and notables who supported the Society of Jesus in founding the Universidad Centroamericana (UCA), the first private Catholic university in Central America.

“Las Brisas,” his wife's farm (as he used to point out, remarking he had no material wealth), was located out of a smaller stream of the San Juan River and became a popular place for intellectuals' and journalists' meetings and visits.

The area's popularity increased when his nephew, catholic priest Ernesto Cardenal, an influential poet and figure of liberation theology, founded 1965 a religious and cultural community in the nearby Solentiname archipelago.

In 1976, many intellectuals met in Las Brisas for Coronel's 70th birthday, including Argentinian writer Julio Cortazar, who was visiting Cardenal in Solentiname.

In 1974, during one of Coronel's sporadic stays in Managua, prepared by the time of his lectures "Three Conferences to the Private Sector," he was kidnapped by the founder and leader of the Sandinista movement, Carlos Fonseca Amador.

He married Nicaraguan German descendant María Kautz Gross (Groß), to whom he dedicated many of his best poems, such as “The Hunter”, “Short Biography of my Wife,” “Love Song for the Autumn” and “Lumber Moon” among others.

One died of cancer in childhood, Christian, and another, named after his father, mysteriously disappeared during the Cold War while studying at the University of Frankfurt, Germany, in 1961.

Twin Ricardo Coronel Kautz was a member of the anti-Somoza political movement known as “The Group of Twelve,” in Spanish ‘’Los Doce’’, and both were Sub Secretaries of the Agrarian Reform Institute between 1980 and 1989.

On March 19, 1994, José Coronel Urtecho, a man now considered one of the most influential poets of the 20th century in Central America, died of skin cancer.

The work of José Coronel was scattered in journals and newspapers until the author agreed to pick up an anthology in his book Pol-la D’Ananta, Katanta, Paranta, published in 1970, subtitled “Imitations and translations".
