Frequently we come across conceptual procedures in his work, but an important role was played by playfulness and sensitivity connecting rationality with gestures. For his work are typical series or rounds, to which he often returned. It was the square that was an important object of investigation for Chatrný. He expressed his admiration for Kazimir Malevich and Alexander Rodchenko in "tributes" on paper. Like many of our artists in the sixties, he built on the foundations of constructivism and the contributions of the Russian avant-garde. The exhibited work comes from the peak period of Chatrný creation. In the collections of the Vysočina Regional Gallery in Jihlava are stored twenty works by Dalibor Chatrný mainly from the 1950s, from which it is possible to follow the gradual transformation of the artist's handwriting and its acceleration in the 1960s. Unlike the older works, which arrived in Jihlava thanks to the transfer from the National Gallery, Cryptograms of points I–III. were acquired by the Vysočina Regional Gallery by purchase in the early 1970s, together with the remarkable Hnízdo (Nest) object.
