 It also contains quatrains from writers and poets who are not known for their quatrains such as Asadi Tusi, Nizami Ganjavi, Fakhruddin As'ad Gurgani and Qabus.Some quatrains are even narrated from statements and rulers such as Fariboz III Shirvanshah, the Seljuq Sultan Tugrul and Shams ad-Din Juvayni.The most significant merit of Nozhat al-Majales, as regards to the history of Persian literature, is that it embraces the works of some 115 poets from the northwestern Iran and Eastern Transcaucasia (Arran, Sharvan, Azerbaijan; including 24 poets from Ganja alone), where, due to the change of language, the heritage of Persian literature in that region has almost entirely vanished.
