In 1530, at the Veste Coburg, Martin Luther wrote his Sendbrief vom Dolmetschen, an open letter on translating. He wrote that he and his helpers had very often searched and asked for fourteen days, or three or four weeks, for one single word. In modern spelling the line reads: Und es ist uns sehr oft begegnet, dass wir vierzehn Tage, drei, vier Wochen ein einziges Wort gesucht und erfragt haben.
