刺桐

Medieval Arab traders called the great port of southern China Zaytūn, probably from the Chinese Cìtóng, the name of the erythrina tree that lined the city's streets. The city is now Quanzhou, in Fujian province, and in the 13th century it was the largest port in the world. Ibn Battuta, visiting in 1345, wrote that it was 'the largest harbour in the world -- I am wrong: in the whole world.' Ships carrying silk, porcelain, and spices departed from Zaytun for Arabia, India, and East Africa.

The smooth, glossy silk fabric produced in and shipped from Zaytun became known in Arabic as zaytūnī, 'of Zaytun.' The word passed into Old French as satin by the 1300s. No one in medieval Europe knew where Zaytun was; the name was just a label on luxury goods arriving from the East. For centuries, European scholars debated whether Zaytun was Canton, Hangzhou, or an imaginary place. It was not conclusively identified as Quanzhou until the 20th century.

The satin weave technique -- where warp threads float over multiple weft threads to create an unbroken, reflective surface -- may or may not have originated in Quanzhou. The technique was certainly Chinese, but it traveled the Silk Road in all directions. What is certain is that the name stuck: satin, from Zaytun, from a tree-lined port that Europeans visited for centuries without knowing its real name.

Satin today is woven from silk, polyester, nylon, or rayon. It lines caskets and lingerie, drapes across theater stages, and wraps chocolates. The word has become a synonym for smoothness itself -- 'satin finish,' 'satin skin,' 'satin sheets.' Quanzhou, meanwhile, was recognized as a UNESCO World Heritage Site in 2021, honored at last for the maritime trade that gave the English language one of its most sensuous words.
