Antun Šoljan, Croatian modern literature novelist, wrote four existentialist novels with serious and difficult topics about generational trauma and anxiety of existence: Traitors (1961.), Short trip (1965.), Harbour (1974.) and Other people on the Moon (1978.). Šoljan is extremely modern novelist because of the inexhaustible inclusion of intertextuality, referentiality and autoreferentiality in his novels. The objective of this work is to show and process Šoljan's second novel, Short trip, and then indicate its importance for the entire Croatian modern literature. In the same department, the other listed novels of Šoljan's theatrology are also elaborated and their interrelation is shown. Short trip is a novel that carries a humane and timeless message about the anguish of existentialism through youthful generation of artists and art historians who are looking for excavations and forgotten frescoes in the Istrian heartland. All of Šoljan’s novels put lost generations in the middle, that is, lonely individuals who are trying to understand the world around them by painstakingly searching for their lost identity.
