When de Greiff returned to Medellín in 1914, he joined the tertulias that gathered in the local cafés of the city, most prominently the ones that met in the café of the bookstore
El Globo. It was there that he became acquainted with the underground cultural movement of his time and began developing and experimenting the style of poetry that would define him later on.A group of 13 young bohemian artist and writers that formed during that time became known as
los Panidas, named so after the god Pan, and included future prominent figures in the Literature of Colombia such as de Greiff and Fernando González. The panidas were influenced by the modernist movement in literature, which in Latin America became known as
modernismo . This movement aimed to reclaim the already established European standards of art and literature and give it a modern and local character; the panidas thus became the precursors of modernism in Colombia, transforming the foreign and strange into local and tangent. De Greiff often exposed Colombian audiences this way, for example to the mystic land of Vikings and fjords by giving it a familiar
antioqueño feel, a combination of the two worlds that were part of de Greiff’s life He also became known for his eclectic use of the language often using a lexicon so unfamiliar to most Spanish speaking audiences of that time that it would sound as if it were a foreign language, and introduced references to obscure or unknown authors and works of art and literature that were not part of standard curricula. Also present in de Greiff’s and the panida’s work was the influence of symbolism, and more significant that of parnassiastic thought, of creating poetry in its purest form to more closely resemble art. De Greiff described the purpose of the panidas in these words:
We were encouraged, above all, by a purpose of renewal. At that time poetry had become too academic. It seemed a mediocre thing, a thing which we must fight against. It was essentially that generational criterion that we were trying to impose.—León de Greiff
The culmination of this artistic group was the publication of a quincenal literary magazine called
Panida in February 1915. This short lived publication of only ten issues was illustrated by Ricardo Rendón first directed by de Greiff, and later by Félix Mejía Arango. De Greiff had its works published for the first time in this magazine under the nom de plume
Leo le Gris, the first one being his
Ballad of the Mad Owls.
No sooner had the magazine been published than the Roman Catholic Church in Colombia banned it outright for fear of corrupting the youth with its pernicious and extravagant content. The public reception was not welcoming either, the writing style of de Greiff and the other panidas was at the vanguard of its time, but too far-off from what mundane Colombian society was familiar with. It did however earn the praise and support of prominent Medellín literati such as writer Tomás Carrasquilla and journalist Fidel Cano Gutiérrez.
Alas the magazine went off circulation in June mostly due to the dispertion of the panidas, some included de Greiff moved to Bogotá, most went into business leaving their artistic aspirations behind, and some chose the nihilist path of suicide. In 1925, when he published his first book
Tergiversaciones, de Greiff dedicated it to the memory of "The 13 Panidas".
Los Nuevos
In 1925 now in Bogotá, de Greiff was now a regular of the tertulias that gathered in the
Windsor café and part of the publication of a new vanguard magazine called
Los Nuevos (es:The New Ones). Directed by Felipe and Alberto Lleras Camargo, de Greiff worked with other writers such as Jorge Zalamea and Germán Arciniegas among others as regular contributors to the magazine.
Los Nuevos was of political, artistic, literary and social content, and aimed to challenge the remnants of exhausted romanticist writings, regionalist politics, and conservative society. This movement followed the path that the panidas had begun in Medellín and that was a representation of modernismo in Colombia much like the ultraist movement in Spain.
Influenced by Vicente Huidobro, de Greiff followed creacionismos standards of poetry, reinventing himself to make each poem unique, translatable, and truly poetic. His poetry is sometimes criticized as standoffish and intricate, but it is regardless true to the art.
Mamotretos
Starting with his first book
Tergiversaciones in 1925, every one of his published books of poetry that was directed by him were named in order as
mamotretos, which in Spanish loosely refers to a bulky jumbled collection of writings that could be loosely interpreted as a tome. The name was both an example of de Greiff's masterful use of language and his humbleness towards his work and himself. His eighth and last mamotreto would be
Nova et Vetera, published a year before his death, and was a collection of new and old found poems of his from even before Panida.
