The specific character of unification of taditional folk culture of utilitarianism and aestheticism in the worldview and everyday life of people, indivisibility of life and existence, perceived well by Rostyslav Rybalchenko (1932 – 2019), the outstanding local historian of Slobozhanshchyna, creator of his own skansen and author of a number of books with the detailed description of material world of rural people of Ukraine in the 20th century, are analyzed in the article. Pragmatic and aesthetic unity of rural everyday tasks is described on the specific examples from the book Rostyslav Rybalchenko and His Rural World. For example, white-washing in a Ukrainian house even in the second half of the 20th century has been not only a forced sanitary-hygienic procedure but also a sacral action with a spiritual context. It has been done at least three times a year: before the Feast Day of the Protection of the Mother of God, Christmas and Easter. In such a way the routine task has become the festive one as a holiday starts psychologically not on the very day of the holiday but from the preparation for it. Besides, tidiness inside the house is not only useful, but also beautiful from the aesthetic point of view. Moreover, it has been filled with religious sense and become the equivalent of the Christian’s state of soul before celebrating-commemorating the most significant evangelical events. In the 1950s it has been easy to do the white-washing because there is little furniture in the houses. According to Rybalchenko’s accurate observation, “the fact that the chamber is not cluttered” has also the following sense: “<…> nothing superfluous can press the consciousness, nothing steals the space”, which is usually scarce as poor people’s houses are rather small. The house is the mirror of the soul, which should not be cluttered. The yard, the orchard, the vegetable garden are all space signs which require a special sense in traditional folk culture of Ukrainians. According to R. Rybalchenko, in peasants’ opinion the homestead space has to be clean, tidy, beautiful as well as uncluttered not because otherwise neighbours would gossip but because of the inner necessity of the majority of the owners. Some attributes of the rural space and domestic equipment, the pragmatics of which is inseparable from the aesthetic component, especially those connected with water: the well, the beam, the anchor, etc., are also analyzed in the article.
