Takht-i-Jahangiri (Black Throne of Jahangir). Prince Salim rebelled against his father Akbar in 1602 and made his seat of official activities at Allahabad. He got this throne made of black touch stone (sang-i-mahak). After his accession Jahangir brought it at Agra and placed it on terrace of Diwan-i-Khas, as is mentioned in Tuzuk-i-Jahangiri by Emperor Jahangir. It was made of touch stone (sang-i-mahak or kasauti) and is very black and shining. This monolithic throne is 3.3 m. long and 2.8 m. broad. Its octagonal pedestals are 39 cm. high. The top of this slab slopes from the centre to the sides like the back of a tortoise. Persian versified inscriptions in Nasta'liq characters, most probably written by Abdullah Mushkin Qalam, are carved in relief against floral background with date A.H. 1011 (AD 1602), mentioning Sultan Salim when Emperor Akbar was still the overlord.
It is interesting to note that there is one specimen of Nastaliq calligraphy in the collection of Rampur Raza Library which contains the date A.H. 1011 (AD 1602) of Abdullah Mushkin Qalam Shah Salimi (i.e. belonging to king Salim Shah) apparently written at Allahabad where his other inscriptions can be seen on the famous monolithic pillar at Allahabad Fort.
When Jahangir brought the throne from Allahabad in 1610 to Agra he got two more inscriptions written by Abdullah Mushkin Qalam carved on the throne mentioning his accession in 1610.
William Hawkins an English traveller noticed this throne at Agra Fort and mentioned in his travelogue.
