His father, also named Antonio, was a modernist poet who published only one book, Otra más alta vida (Another higher life) in 1919.

He published his first book in 1960, Sublevación inmóvil (Motionless revolt), a work that was a runner-up for the Adonais prize.

The ideological and existential crisis of the poet is felt in his next book Descripción de la mentira (A description of the lie), León 1977, a long poem that marked a shift towards a total maturity.

Later publications are Lápidas (Tombstones) (Madrid, 1987) and Edad (Age), a volume collecting all his poetry until 1987, revised by the author, and that won the National Prize for Literature in Spain.

In 1992, Libro del frío (Book of the cold) was published, making him one of the most important poets in Spanish.

Arden las pérdidas (Losses are burning) was published in 2003, a book that crowns the period started in Descripción de la mentira.

Critical reception to Gamoneda's poetry has always been positive since the poet began to publish: "Gamoneda's word is tight and solid, as emerging from silence to remain within it, to return to it, a word as if detached from the wasteland, from the contemplation of a desolate landscape, born from the cold expansion to leave its melancholy record of stripping ...

"[3] "A voice tested and immersed and submerged in time, in the hallucinogenic unpredictability of the Spanish historical circumstance, turned around the spacious event of a "poetic life" followed by Gamoneda; but a voice that also occupies with authority its own place in the vast field of Spanish literature, and that takes its place, running the conquest of his space and most genuine figure in a quiet strategy whose secret is delay, silence (and some exile), and which is supported by all levels of legitimacy one can think of [...].

Only the events internalized matter - scarce, hurtful - and they offer their stiff-necked recurrence, their metamorphosis, their staying...It is a peculiar sort of autobiographical way, non narrative or directly referential, but woven in the constant images and the center of interest, the elements that became emblematic, the figures and individuals.
