Sucre studied at the National College of Kumana from where he obtained a degree in philosophy at the age of 20. He wanted to continue his studies at the Central University of Venezuela, however, an epidemic that broke out in the city of Caracas forced him to stop studying for 2 years. During this time he used it for writing and then published his first works, poems and stories in magazines of the time. He continued his studies in Caracas from 1912 and received a degree in Law, Letters and Languages (including ancient and modern Greek ).
The author, despite his withdrawn character, constantly produced texts of various kinds and soon gained a great reputation; the influence of philosophy in his work is remarkable, as well as the love for languages in his brilliant translations. The elements that compose his work are the poetic prose, the short essay and the narration.
In 1929 he was offered the post of consul of Venezuela in Switzerland. At that time, the insomnia that always had been tormented him became unbearable. He went to hospitals and psychiatric clinics to find a solution but to no avail. Weakened by health problems caused by lack of sleep, in a moment of despair, a few days after he turned 40, on June 13, 1930, he took an overdose of barbiturates and ended his life and the pain.
Sucre had maintained throughout his life close ties with the authoritarian regime of Juan Vicente Gomez, with whom he had a personal relationship, and for that reason, his work had been discredited, but over time, the power of his poetry were unfolded, restoring him as one of the most gifted and important poets of his country.
