Marco Polo left Europe in 1271 accompanied by his father and an uncle, and is one of the earliest European travellers who claimed to have visited China. Interestingly, his name has come to be associated with a Yuan Dynasty (1279-1368) ceramic that has long resided in the Treasury of San Marco in Venice.
A recent analysis of the piece published in 2017 by Cambridge University Press confirms that the ceramic does appear to date to the 13th century. It was Oscar Raphael who visited the Basilica of San Marco in Venice in 1932 who suggested that the jar housed in its Treasury could have been brought to Europe by Marco Polo from China, as he rightly identified it as qingbai.
Such wares from the Dehua and other Fujian provincial kilns were widely exported during this period, and it is possible that Marco Polo or another traveller found, bought or was gifted the vase.
But it’s just as likely it came to end up in the Venice treasury as part of the spoils of the Fourth Crusade of 1204, which was the origin of a significant number of other items that form the basilica’s collection. “Following the conquest of the Byzantine capital, crusaders brought many ornate objects back to Venice, including incense holders, chalices, bowls, ewers, cruets, and reliquary caskets” [reference]…and perhaps even the qingbai vase that today carries Marco Polo’s name.
