This paper deals with the cosmic component of Antun Branko Šimić’s expressionist poetry, more precisely his collection Preobraženja (Metamorphoses). The basic definition of the cosmic stems from the sacralization of the ontological being, which expressionists see beyond our reality, the amorphous and impersonal world beyond expression and spiritual experience. The cosmic in Šimić’s work could be detected in the plans of the concept of art itself, which strives for postulates of abstract expressionism in the “cosmisation” of the human being, where one is perceived as an expressionist neophyte who experiences disintegration, death, and metamorphosis. Furthermore, the cosmic aspect can be found in the astral spaces which Šimić thematizes, in which one encounters the gynocratic principle of lunarity and stellarity, and, accordingly, the aquatic symbolism. Šimić’s expressionist musicality discusses the universalism of the striving for individuality that the expressionists seek for art, and the colours they use in an antimimetic manner express the transcendency of the human body and the being outside the framework set by the technocratic world and mimesis. The whole “cosmic” consciousness in Šimić’s poetry arises from the Nietzschean fall, which is not a possibility, but a certainty, followed by transformation.
