Mahasti Ganjavi, one of the prominent quatrain poets of the 5th and 6th centuries AH, has managed to create beautiful and vivid images of love and the relationship between the lover and the beloved in her quatrains. In her poetry, she expresses the lover-beloved relationship through the use of vivid imagery and the creation of colorful contrasts, to the extent that some scholars believe none of the ancient poets have been able to speak with the same grace and sweetness as she does. Given that Mahasti's poetry has a unique style, the main objective of this research is to highlight the feminine characteristics in her quatrains and to examine her position as a pioneering and innovative poet of her time, as well as to analyze the three main elements of lyrical literature: "love," "the lover," and "the beloved." The significance of this research lies in analyzing the reflection of femininity in Mahasti's poetry and evaluating her role in the development of romantic content in Persian poetry, which can greatly contribute to understanding the social, cultural, and literary conditions of that era. This research has been conducted in a library-based and descriptive manner. By examining the works of Mahasti Ganjavi, we find that she is a modern and courageous poet of the Seljuk era who, through her creative and free-spirited poetry, describes earthly love and diverse beloveds, playing an important role in enriching the romantic content of Persian literature.
