Love has been one of the most important topics in the history of Persian literature, and Nizami lit a light in this field that brought many imitators in his wake. In the meantime, Taskin Shirazi followed his path in composing Falaknaznameh, and his work with the theme of reflecting a love story, at least in the south of Iran, became famous. Based on this, in this research, it has been assumed that the main topic of this work can be analyzed with Sternberg's love triangle theory. The research method is analytical-descriptive. And the research question was, according to Sternberg's theory, what components does love have in this work and what are the strengths and weaknesses of the characters' lovemaking from this perspective? This research showed that the two loves of "Falknaz-Cervu" and "Khorshid-Afarin-Gol" are complete in the early stages of the story and the heroes' performance is in accordance with all three sides of the triangle; including intimacy, passion and commitment, but these two main loves have suffered from a lack of commitment in the continuation of the story. In contrast, the heroes are anti-heroes who use power and wealth as a pretext to reach their beloved and have been unsuccessful. During this research, ten different loves were briefly examined, matched with theory, and conclusions were drawn.
