In 1912 he and his brother, along with their friend Mikhail Le-Dantyu, became enthusiastic about the Tbilisi painter Niko Pirosmanashvili; Ilya's article about him, "Khudozhnik-samorodok" ("A natural-born artist"), his first publication, appeared in the February 13, 1913, issue of Zakavkazskaia Rech'.
During World War I Zdanevich returned to the Caucasus as a newspaper correspondent,[2] and from 1917 to 1919 he lived in Tbilisi, where he published several collections of poetry in the zaum style (Yanko Krul Albansky, Ostraf Paskhi, and Zga Yakaby).
In 1923 he began his novel Parizhachi, about four couples who agree to dine together in the Bois de Boulogne; in the course of two and a half hours (each chapter has an exact time for a title, from 11.51 to 14.09) they all manage to betray each other, and the novel itself breaks all manner of orthographic, punctuational, and compositional rules.
Set in a mythical Georgia among mountaineers, on the surface a crime novel, it is actually a fictionalized history of the Russian avant-garde, full of allusions to world literature; it could be said to anticipate magic realism.
"[5] Zdanevich's 1923 poster for his and Tristan Tzara's Soirée du coeur à barbe [Evening of the bearded heart] is a widely known example of avant-garde typography and graphic design.
