Abstract: In her research Seredina considers religious and aesthetic views of Apollon Grigoriev reflected on the poetics of his fiction and epistolary heritage. The focus is on religious ecphrasis, that is, descriptions of icons, images of the Madonna, frescoes, temples and monasteries. An extensive material is drawn such as texts of Grigoriev’s early prose of the mid-1840s, essays and letters of the turn of the 1850s-1860s, as well as the final work of the writer, the memoirs "My Literary and Moral Wanderings". The theoretical basis for the immanent comparative analysis is the works of N.V. Braginskaya, N.G. Morozova, E.V. Yatsenko on ecphrasis. The study found that Appolon Grigoriev put forward different requirements in evaluating a secular work of art and a work claiming to be sacred. The author of the article also traces the peculiarities of interaction between the categories of nationality and sacredness in the concepts of Appolon Grigoriev. In this article Seredina continues her analysis of the theme of ecphrasis in the prosaic heritage of Appolon Grigorieva who had not previously attracted the special attention of literary critics.
