Abolhassan Atabaki said the inscription is written next to one of the three-domed castles on a rock, he noted, adding that each of the castles has a long history, ILNA reported.
Atabaki explained that the reason for writing Sa’adi’s poems on rocks is the undeniable influence of the poet on the Persian language and his simple writing style.
Najmeh Ebrahimi, a historian, said that many centuries after the death of the poet, his poems were considered precious by princes and the nobility, such as Ibrahim of the Ottoman Empire and Amir Timur Gurkani.
