Abstract: The article is devoted to the topic that has never been studied before which is the interior details and development of the interior details in Apollon Grigoriev's fiction. The article is devoted to the peculiarities of the perception and description of the surrounding space by the hero of the memoirs 'My literary and moral wandering' (1862, 1864). Seredina traces back how the interior in Apollon Grigoriev's house and the writer's attitude to the external world (the world of objects) were reflected in the poetics of Grigoriev's early prose of mid 1840s. In addition, the author sets a task to demonstrate the connection between the interior and psychological portraits of the main heroes. The basis for the comparative analysis of Apollon Grigoriev's prose is the first theoretical research of the interior performed by I. Sudoeva. Despite the fact that in the majority of cases the description of the interior in Grigoriev's prose is pointing out individual elements of the interior (lighting, bed and door) and gives an insight into the internal world of the heroes. The universality of the description achieved through the absence of details helps to create the portrait type. The dreaminess of the hero of the memoirs, fed by the evenings spent on a bed without light, in early prose is embodied in the type of hero-dreamers the description of which is accompanied by a bed and the light of a burning candle. The audio perception of space, characteristic of the hero of the memoirs, turns into an aggravated attention to the sounds of wanderers in early prose which helps to expand the space of the room and give an idea of its structure.
