The article is a study on presence and functionality of objects in a Cosmicomics collection of short stories written by Italo Calvino. These philosophical fantasy stories, presents a very individual vision of our galactic before life formation on Earth. Objects, ubiquitous in our life environment, place matter in order and are a testimony of homo faber's activity. They receive symbolic meanings and also serve as evidence of ‘possession over existence' supremacy. Objects in Calvino's cosmic universe function as fictional, stylistic, identifying, reconnaissance, metaphorical and ideological ones. Typology of their functionality - illustrated with examples - and defining these objects meaning both allow us to conclude on a vision of a human being and the world but also the specific fictional world poetics in the work of this Italian writer.
