The small inscription in the outer border reads: Qazan carpet wa shuraka (and partners). The large inscription reads: Hasb al-amr hazrat-e ashraf asa'd amjad arfa' wala shahanshahzadeh 'azam zell-i sultan wa farmayesh-e jalalatma'ab ajall nasr al-mulk (Commissioned by his excellency the most noble, the most fortunate, the most splendid, the exalted, the elevated, son of the king of kings, the most great Zell-i Sultan, and ordered by the one who has the rank of being great Nasr al-Mulk). Zell-i Sultan was the eldest son of Nasir al-Din Shah. His mother was without appropriate status therefore he was unable to ascend to the throne. He became the Governor of Isfahan 1870-1875, subesquently controlling half of the entire country. Nasrulla Khan, who was given the title of Nasr al-Mulk, was one of Nasir al-Din Shah's entourage on his trip to Europe in 1873-4, although there is no known linked part from this carpet between this holder of the title and Zell-i Sultan.
