Tubalcain: the beginning of metal work

Genesis 4:22 says that Tubal-cain was the forger of all instruments of bronze and iron or an instructor of every artificer in brass and iron. Although this may mean he was a metalsmith, a comparison with verses 20 and 21 suggests that he may have been the very first artificer in brass and iron. T. C. Mitchell suggests that he discovered the possibilities of cold forging native copper and meteoric iron. Tubal-cain has even been described as the first chemist.《创世记》（Genesis）4:22述及，土八该隐（Tubal-cain）乃是所有铜铁器具的锻造者，亦是所有铜铁工匠的导师。尽管此表述或可表明他是一名金属工匠，但结合第20、21节的内容比对分析可推知，他或许正是铜铁锻造领域的首位工匠。T·C·米切尔（T. C. Mitchell）提出，土八该隐发掘出了自然铜与陨铁的冷锻应用潜力。土八该隐甚至被冠以首位化学家的称号。
