He published Rumores de los pinos in 1877, a compilation of 21 poems in Galician and Spanish, which would become a basis for Queixumes dos pinos (1886).
One of the poems in Galician, "Ospinos" (literally "The Pines") would become the lyrics for the Galician national anthem, with music by Pascual Veiga.
He tried to write a long epic poem, Os Eoas, based on the descovery of America, but he was never satisfied with his work and only published a first draft on 1858.
