The landscape of mountains at night from the collection of Borys Voznytskyi Lviv National Art Gallery is a characteristic work of Vasyl Poliovyi from the early 1970s, with their inherent technical experiments. This has influenced the image's colouring scheme and optical qualities, which are visible only when viewing the original artwork from different lighting angles. Based on the specific shape of the depicted mountains and the probable viewpoint from which the sketch was made, this mountain range belongs to the Skole Beskids. To achieve a unique complex colour scheme, the artist used tempera-like paints and original emulsions with metallic paints of bronze shades. This suggests that the artist drew inspiration from historical examples of capturing special lighting during the dark hours, particularly in intense moonlight. Among the significant characteristics of the painting is the skilful execution of a "night" landscape with a particular colour temperature and, in addition, the formation of an emotionally intense and mystical atmosphere. The artwork reveals a monumental and almost epic approach to the narrative, with an anthropic dimension present exclusively from the author's perspective. The viewer is presented with a situation where the ability to co-create is a primary quality and allows the perception of the work to be derived from their own visual experience, as well as emotional and intellectual characteristics.
