In the 16th century, when most grain imports to the British Isles came from Poland, Polish travellers arrived as merchants and diplomats, usually on the Eastland Company trade route from Gdańsk to London. Polish people are mentioned in Shakespeare's "Hamlet" (e.g. "sledded polack"), which Israel Gollancz attributes to influence of the book, "De optimo senatore" (The Accomplished Senator), by Laurentius Grimaldius Goslicius (Wawrzyniec Grzymała Goślicki, a Polish bishop and noble). Gollancz further speculated that the book was also an inspiration for Shakespeare to create the character Polonius, which is Latin for "Polish".
