- At different times in Chinese history, Confucius (trad. 551–479 BCE) has been portrayed as a teacher, advisor, editor, philosopher, reformer, and prophet. The name Confucius, a Latinized combination of the surname Kong 孔 with an honorific suffix “Master” (fuzi 夫子), has also come to be used as a global metonym for different aspects of traditional East Asian society. This association of Confucius with many of the foundational concepts and cultural practices in East Asia, and his casting as a progenitor of “Eastern” thought in Early Modern Europe, make him arguably the most significant thinker in East Asian history.

Lead is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.
