Khaghani is one of the greatest Qasida composers in the Persian literature in the sixth century. One of the main stylistic features of this era – which is more seen in the poets of Azarbayejan- is extensive use of the terms and beliefs of different sciences in their time, including astronomy. Khaghani who was a master in astronomy has used the details of this science in creating poetic images. Sometimes he combines astronomical terms and beliefs with mythological and religious beliefs along with different types of semantic and verbal parallels and various figures of speech and thought in a way that astonishes the reader.
