  The history of Swedish iron and steel industry The Swedish iron and steel industry has a long history beginning in the Middle Ages. The Period of Osmund It was merchants from Lübeck who, in the Middle Ages, began to interest the kings of Sweden in the export of iron on a large scale. It was also at that time that German mine owners and merchants acquired the rights to run their own operations in Sweden's miningareas and trading communities. Mining and foreign trade thereby paved the way for the integration of Sweden into the mainstream of European civilisation. The consequence was a new economic structure and the emergence of a broader society in the formerly agrarian Sweden. The Swedish iron exports during the Middle Ages comprised so-called osmunds– a standardised format of high-grade forged iron with a weight of just 3 hectograms.The osmund was an accepted object of barter both in Sweden and abroad and was also used as a form of payment with its value being determined by the C...

太平天国干王洪仁玕绝命诗二首

  其一: 春秋大义别华夷,时至于今昧不知。 北狄迷伊真本性,纲常文物倒颠之。 志在攘夷愿未酬,七旬苗格德难侔。 足根跟踏破山云路,眼底空悬海月秋。 意马不辞天地阔,心猿常与古今愁。 世间谁是英雄辈,徒使企予叹白头。 其二: 英雄吞吐气如虹,慨古悲今怒满胸。 狁侵周屡代恨,五胡乱晋苦予衷。 汉唐突厥单于犯,明宋辽元鞑靼凶。 中国世仇难并立,免教流毒秽苍穹。 北狄原非我一家,钱粮兵勇尽中华。 诳吾兄弟相残杀,豪士常兴万古嗟。
