This type of representation of a Bactrian camel denotes important foreign influences during the Tang era thanks to the Silk Road, which resulted in a keen interest in foreignreligions at the Court and among the elite, but also for foreignphilosophies, music, and all the arts from the West or the East.
With the long caravans, the Chinese discovered these astonishing animals led by "barbarians". They did not mount them themselves, although some bred them and hired the services of western grooms, an essential element in transport to the cities of Lanzhou, Chang’an and Luoyang. Carrying all kinds of exotic products, the camel was a living symbol of prosperity.
