On July 23, 1927, de Greiff married María Teresa Matilde Bernal Nicholls, a Colombian of English descent whom he met through his sister Leticia.

A group of 13 young bohemian artist and writers that formed during that time became known as los Panidas, named after the god Pan, and included future prominent figures in the Literature of Colombia such as de Greiff and Fernando González.

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.

This short lived publication of only ten issues was illustrated by Ricardo Rendón first directed by de Greiff, and later by Félix Mejía Arango.

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.

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).

[11] 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.

Influenced by Vicente Huidobro, de Greiff followed creacionismos standards of poetry, reinventing himself to make each poem unique, translatable, and truly poetic.

The relationship of his poetry to music has been noted by Stephen C. Mohler in his doctoral thesis (The Poetic Style of León de Greiff, Ann Arbor, Michigan,1969).

That same year on November 21 de Greiff was arrested along with Diego Montaña Cuéllar, Alejandro Vallejo, and Jorge Zalamea for “political reasons” that were never explained.

De Greiff had been victim of the political and violent turmoil that had been engulfing the country known as La Violencia and his left-leaning tendencies and relations made him a target of the newly elected conservative Government.

He was released on December 6; shortly after, he presented his letters of resignation to the Ministry, and steps down as Director of Cultural Promotion and Fine Arts and as Professor at the National University on March and May 1950 respectively.

De Greiff who had not been an open communist was nevertheless of leftist tendencies and fit right in with the crowd, and after the summit he traveled to, at the invitation of the respective governments, the Soviet Union, the People’s Republic of China, East Germany, Austria, the SFR Yugoslavia, and France.

This bohemian and independent quality put him at odds with the appointed ambassador while de Greiff was serving as secretary, especially for his indiscretions regarding a relationship he had with the Chinese Embassy, which he frequented on various occasions at their invitation.

While in Sweden, de Greiff gained fame and popularity and even maintained a friendship with His Majesty King Gustaf VI Adolf, who in 1964 awarded him the Order of the Polar Star in the grade of Knight.

[16] In 1975 in recognition of his diplomatic work de Greiff was awarded the Order of San Carlos in the grade of Grand Officer by the Government of Colombia.

[18] He also received various tributes including one from the Colombo-Argentinian Cultural Institute in 1955, (Instituto Cultural Colombo-Argentino), one from the National College of Journalists in 1961 (Colegio Nacional de Periodistas) presented by Gabriel García Márquez, an honoris causa doctorate in literature from the University of Valle on July 16, 1975, and in that same year another tribute from the National Association of Financial Institutions (Asociación Nacional de Instituciones Financieras, ANIF), presented to him by its then president Belisario Betancur.
