This research deals with the movement of time in the Beirut City of the World trilogy by the Lebanese novelist Rabih Jaber. This novel included a present reading of history in which the writer was inspired by the technique of reflexive self-awareness, which is one of the characteristics of the postmodern novel, which led to multiple temporal paths that organize the plot of the novel.The study seeks to shed light on how the novel builds its temporal system, and how the novelist invests this postmodern technique in achieving long-term transitions extending between the nineteenth and twenty-first centuries, as well as focusing on the features of circular time that appeared in the novel, which the study addressed by research and analysis. The study did not ignore the typical temporal paradoxes that control the rhythm of narrative time, such as remembrance and anticipation, as well as descriptive pauses that perform multiple functions, such as disrupting the narrative as well as the aesthetic rhetorical function. .This descriptive, interpretive reading sought to understand the movement of time in this novel, which represented the Arabic novel keeping pace with all the post-modern intellectual developments that appeared in the West.
