This paper aiming to contribute to the panel on “Semiotic and Artistic Realities (Małgorzata Gamrat)” will introduce the participants of the IASS/AIS World Congress 2024 in Warsaw, devoted to “Signs and Realities”.This paper will present a systematic analysis of signs and the reality of nature in the works of Marina Tsvetaeva. The semiotic reality of nature in Tsvetaeva's work developed as a reaction to the representations of the natural world by the Symbolists, under whose influence her creativity was shaped. Unlike their disdain for nature, marked by "diabolical skepticism," Tsvetaeva proposed her own vision. She regarded nature as one of the "most beloved things in the world," believed that "everything can be understood through nature," and called it her teacher; she equated the laws of nature with the laws of art. According to Tsvetaeva, the goal of art is to use the reality of nature (and the visible world more broadly) as a source of symbols connecting the physical and metaphysical worlds. Nature became both an object of the poet's special reflection and a means of characterizing the reality of life and the reality of death. She used signs of nature to describe actions, characteristics of loved ones and relationships, herself, and in reflection on creativity, which allowed her - through nature - to engage with the realm beyond reality, the metaphysical sphere.
