LTJuozas Petrėnas (1896–1980), savo prozą skelbęs Petro Tarulio vardu, prieškariu garsėjo kaip vienas ryškiausių lietuvių modernistų. Bet menkai težinoma jo pokarinių apysakų knyga, parašyta 1948 m. gyvenant pabėgėlių stovykloje Vokietijoje. „Žirgeliai padebesiais“ ilgam liko tinkamai neperskaityti: nesuvoktas modernistinis sprendimas, neatpažintas jo kodas, neiššifruota tikroji prasmė. O knyga verta rimto dėmesio. Literatūros tyrinėtojos Dalios Striogaitės straipsnyje ji atidžiai interpretuojama ir aptariama kaip novatoriškas to meto lietuvių literatūros faktas, nepraradęs ir šiandien estetinės vertės nei aktualumo.
ENDuring the period before the Second World War, Juozas Petrėnas (1896–1980), writing under the pseudonym Petras Tarulis, was one of the most celebrated Lithuanian authors of the Modernist movement. However, his book of short stories about the postwar period, which was published in 1948 in a refugee camp in West Germany, is hardly known today. "Žirgeliai padebesiais" has not been thoroughly analysed for quite a long time, and it deserves more attention. Its Modernist features were not understood, his code was left undeciphered, and its true meaning was not found. In the article by the literature researcher Dalia Striogaitė, the book is interpreted and described as a very modern phenomenon for its time, which has not lost its importance or its aesthetic value.
