Rashiduddin says of Tabriz that there were gathered there under the eyes

of the Padishah of Islam ‘philosophers, astronomers, scholars, historians,
of all religions, of all sects; people of Cathay, of Machin, of India, of
Kashmir, of Tibet, of the Uighr and other Turkish nations, Arabs and
Franks
Rashiduddin says of Tabriz that there were gathered there under the eyes
of the Padishah of Islam ‘philosophers, astronomers, scholars, historians,
of all religions, of all sects; people of Cathay, of Machin, of India, of
Kashmir, of Tibet, of the Uighr and other Turkish nations, Arabs and
Franks.’ Ibn Batuta, ‘I traversed the bazaar of the jewellers, and my eyes
were dazzled by the varieties of precious stones which I beheld. Handsome
slaves, superbly dressed, and girdled with silk, offered their gems for
sale to the Tartar ladies, who bought great numbers. [Odoric (ed. Cordier)
speaks also of the great trade of Tabriz.] Tabriz maintained a large
population and prosperity down to the 17th century, as may be seen in
Chardin. It is now greatly fallen, though still a place of importance.’
