The main purpose of this article is to identify the reasons which caused the dominance of water as a literary topos in poetry of Krzysztof Kamil Baczyński. For the poet, the images related to water serve to amplify the impression of dynamism of existence, dualistic organization of matter and the mutual contradictions of the principles that influence the world. The author’s interpretation of the liquidity tropes shows the importance of progressivism, mythicization and the principle a recentori for this poetry. Additionally, some emphasis is put on the integration of destruction and rebirth, the issue of uncertainty about acquired knowledge, the idea of reality as a structure full of mirrors and the creation of the literary persona as an ontologically irresolvable one. Crucial for this analysis are the connections between the use of said motifs of water and the notions of variabilism by Heraclitus of Ephesus, the hierophany of Mircea Eliade, apocatastasis and the idea of the unity of opposites.
