Ambrogi's narrative was influenced by romance and Spanish American modernism and his stories are chronicles of all aspects of traditional peasant life in El Salvador.

The son of an Italian immigrant, at 16 years old, he met the Nicaraguan poet Rubén Darío.

He received an elite training in literature to the point that he was arguably the best informed of his era in El Salvador.

He never married or had children, although his brother Constantino Ambrogi Acosta settled in Nicaragua where their offspring have continued the literary tradition.

Notable works include "Cuentos y Fantasías" (1895), "Máscaras, Manchas y Sensaciones" (1901), "El Libro del Trópico" (1907), "Sensaciones del Japón y de la China" (1915) and "El Jetón" (1936).
