Of the eleven jewelled recesses formed around it for cushions, the middle one, intended for the seat of the emperor, cost one million rupees (nearly £100,000). Among the jewels set in this recess was a ruby worth a hundred thousand rupees (about £10,000), which Shah Abbas, the King of Iran, had presented to the late Emperor Jahangir, who sent it to his present Majesty when he accomplished the conquest of the Deccan. On it were engraved the names of Sahib-kiran (Timur), Mir Shah Rukh, and Mirza Ulugh Beg. When it came into the possession of Shah Abbas in course of time, his name was added, and when Jahangir obtained it, he added the name of himself and of his father. Now it received the addition of the name of his most gracious Majesty Shah Jahan. At the command of the emperor, a poem by Haji Mohammad Jan, the final verse of which contained the date, was placed upon the inside of the canopy in letters of green enamel. On his return to Agra, the emperor held a court and sat for the first time upon his throne.*

* This was on March 22nd, 1635, marking the seventh formal anniversary of Shah Jahan’s accession. The home of the throne would later be the Hall of Audience in the Red Fort at Delhi. Agra lies about 137 miles southeast of Delhi.
