While his circle of admirers grew, patrons were grudging in their admiration. Ultimately, in 1617 through the influence of the Duke of Lerma, he was appointed honorary chaplain to King Philip III of Spain, but did not enjoy the honor long.
He maintained a long feud with Francisco de Quevedo, who matched him in talent and wit. Both poets composed lots of bitter, satirical pieces attacking one other, with Quevedo criticizing Góngora's penchant for flattery, his large nose, and his passion for gambling; He was also known to be gay. Quevedo even accused his enemy of sodomy, which was a capital crime in XVII century Spain. In his "Contra el mismo (Góngora)", Quevedo writes of Gongora: No altar, garito sí; poco cristiano, / mucho tahúr, no clérigo, sí arpía. Góngora's nose, the subject of Quevedo's "A una nariz", begins with the lines: Érase un hombre a una nariz pegado, / érase una nariz superlativa, / érase una nariz sayón y escriba, / érase un peje espada muy barbado.
This angry feud came to a nasty end for Góngora, when Quevedo bought the house he lived in for the only purpose of ejecting him from it. In 1626 a severe illness, which seriously impaired the poet's memory, forced him to return to Cordoba, where he died the next year. By then he was broke from trying to obtain positions and win lawsuits for all his relatives.
An edition of his poems was published almost immediately after his death by Juan López de Vicuña; the frequently reprinted edition by Hozes did not appear until 1633. The collection consists of numerous sonnets, odes, ballads, songs for guitar, and of some larger poems, such as the Soledades and the Fábula de Polifemo y Galatea (Fable of Polyphemus and Galatea) (1612), the two landmark works of the highly refined style called "culteranismo" or "Gongorism." Miguel de Cervantes, in his Viaje del Parnaso, catalogued the good and bad poets of his time. He considered Góngora to be one of the good ones.
Velázquez painted his portrait, and numerous documents, lawsuits and satires of his rival Quevedo paint a picture of a man jovial, sociable, and talkative, who loved card-playing and bullfights. His bishop accused him of rarely attending choir, and of praying less than fervently when he did go. Gongora's passion for card-playing ultimately contributed to his ruin. Frequent allusions and metaphors associated with card-playing in Góngora's poetry reveal that cards formed part of his daily life. He was often reproached for activities beneath the dignity of a churchman.
The word culteranismo blends culto ("cultivated") and luteranismo ("Lutheranism") and was coined by its opponents to present it as a heresy of "true" poetry. The movement aimed to use as many words as possible to convey little meaning or to conceal meaning. "Góngora's poetry is inclusive rather than exclusive", one scholar has written, "willing to create and incorporate the new, literally in the form of neologisms.
Góngora had a penchant for highly Latinate and Greek neologisms, which his opponents mocked. Quevedo lampooned his rival by writing a sonnet, "Aguja de navegar cultos," which listed words from Gongora's lexicon: "He would like to be a culto poet in just one day, / must the following jargon learn: / Fulgores, arrogar, joven, presiente / candor, construye, métrica, armonía... Quevedo actually mocked Gongora's style in several sonnets, including "Sulquivagante, pretensor de Estolo. This anti-gongorine sonnet mocks the unintelligibility of culteranismo and its widespread use of flowery neologisms, including sulquivagante (he who plies the seas; to travel without a clear destination); speluncas ("caves"); surculos (sprouts, scions). He was also the first to write poems imitating the speech of blacks.
He has been called a man of "unquestioned genius and almost limitless culture, an initiator who enriched his language with the vast power, beauty, and scope of a mighty pen. As far away as Peru, he received the praise of Juan de Espinosa Medrano (ca. 1629—1688), who wrote a piece defending Góngora's poetry from criticism called Apologético en favor de Don Luis de Góngora, Príncipe de los poetas lyricos de España: contra Manuel de Faria y Sousa, Cavallero portugués (1662).
As Dámaso Alonso has pointed out, Gongora's contribution to the Spanish language should not be underestimated, as he picked up what were in his time obscure or little-used words and used them in his poetry again and again, thereby reviving or popularizing them. Most of these words are quite common today, such as "adolescente", "asunto", "brillante", "construir", "eclipse", "emular", "erigir", "fragmento", "frustrar", "joven", "meta", and "porción".
Góngora's poems are usually grouped into two blocks, corresponding more or less to two successive poetic stages. His Fábula de Polifemo y Galatea (Fable of Polyphemus and Galatea) and his Soledades are his best-known compositions and the most studied. The Fábula is written in royal octaves (octavas reales) and his Soledades is written in a variety of metres and strophes, but principally in stanzas and silvas interspersed with choruses.
Góngora's Fábula de Polifemo y Galatea (1612) narrates a mythological episode described in Ovid's Metamorphoses: the love of Polyphemus, one of the Cyclops, for the nymph Galatea, who rejects him. In the poem's end, Acis, enamored with Galatea, is turned into a river.
Góngora's Fábula de Píramo y Tisbe (Fable of Pyramus and Thisbe) (1618) is a complex poem that mocks gossiping and avaricious women. Góngora also wrote sonnets concerning various subjects of an amatory, satirical, moral, philosophical, religious, controversial, laudatory, and funereal nature. As well as the usual topics (carpe diem etc.) the sonnets include autobiographical elements, describing, for example, the increasing decrepitude and advancing age of the author.
He also wrote plays, which include La destrucción de Troya, Las firmezas de Isabela, and the unfinished Doctor Carlino.
Although Góngora did not publish his works (he had attempted to do so in 1623), manuscript copies were circulated and compiled in cancioneros (songbooks), and anthologies published with or without his permission. In 1627, Juan Lopez Vicuña published Verse Works of the Spanish Homer, which is also considered very trustworthy and important in establishing the Gongorine corpus of work. Vicuña's work was appropriated by the Spanish Inquisition and was later surpassed by an edition by Gonzalo de Hozes in 1633.
The Generation of '27 was the first to attempt to self-consciously revise baroque literature. Dámaso Alonso wrote that Góngora's complex language conveyed meaning in that it created a world of pure beauty. Alonso explored his work exhaustively, and called Góngora a "mystic of words. Alonso dispelled the notion that Góngora had two separate styles –"simple" and "difficult" poems- that were also divided chronologically between his early and later years. He argued that Góngora's more complex poems built on stylistic devices that had been created in Góngora's early career as a poet. He also argued that the apparent simplicity of some of Góngora's early poems is often deceptive.
Lorca presented a lecture called "La imagen poética en don Luís de Góngora" at the Ateneo in Seville in 1927. In this lecture, Lorca paid Jean Epstein the compliment of comparing the film director with Góngora as an authority on images.
