纪录片《大英博物馆世界简史》 057海德薇玻璃杯（8）（在线收听）

"Acre, which is now in Israel, became the most important commercial port in the eastern Mediterranean, which meant that shipping from the West was bringing out European cloth and bringing back to the West spices. And we have a fascinating list of commodities traded in the port of Acre in the middle of the thirteenth century, with the customs duties that were due on each commodity. And that mentions Muslim pottery. It doesn't actually mention these glass beakers, but it mentions Muslim pottery as one of the main items that would have been taxed. So the appearance or survival of beakers of this sort in Europe has to be seen in the context of the enormous trade between the West and the Levant, and further east to furthest Asia, that was passing through a Crusader port."

位于今以色列境内的阿卡是地中海东岸地区最重要的贸易中心。来自西边的船运来欧洲的布匹，换作香料带回欧洲。我们有一张有趣的清单，罗列了十三世纪时在阿卡港交易过的商品，并附有每种商品的关税额。这份清单并没有列出这些玻璃杯，但提到穆斯林的陶器是会被课税的主要商品。因此，欧洲出现以及留存这种玻璃杯的现象，应当由欧洲与黎凡特之间大规模的贸易背景来解释。以这个十字军港口为中转的贸易甚至延伸到了更为遥远的东方乃至亚洲腹地。
