Lead

Origin

The etymological origin is the decisive canonical vocabulary of Latin 'plumbum (lead)' — the decisive canon becoming the etymology of element symbol 'Pb' — and Greek 'mólybdos (μόλυβδος mólybdos, lead)' and English 'lead' deriving from Germanic 'lauda'. The decisive natural history canon is the decisive canon of the Roman Pliny the Elder's (Pliny the Elder, 23-79) Natural History (Naturalis Historia) Book 34 chapters 156-164 of the 1st century — 'plumbum nigrum (dark lead, real lead) and plumbum candidum (white lead, tin) distinguished as two kinds', and the decisive seven metals canon is the decisive canon of the Hellenistic seven metals (gold = sun, silver = moon, copper = Venus, iron = Mars, tin = Jupiter, mercury = Mercury, lead = Saturn). The decisive archaeological canon is the decisive canon of the lead beads of Çatalhöyük (Çatalhöyük) of Turkey of c. 7000 BCE. The decisive Roman canon is the decisive canon of the use of lead water pipes (plumbarius) in Rome of the 1st century — the decisive canon of the etymology of 'plumbing'. The decisive Bible canon is the decisive canon of 'Pharaoh's army sank like lead' in Exodus 15:10. The decisive alchemical canon is the decisive canon of the medieval transmutation of Saturn's lead into gold — the decisive canon of the primal heavy matter (prima materia).

Cultural Significance

Lead is not merely a metal icon but the canonical iconographic figure of the decisive Mesopotamian-Greco-Roman-Christian-alchemical canon, traversing the lead beads of Çatalhöyük of c. 7000 BCE, Exodus 15:10 of the Old Testament, the metal of Saturn (Saturn planet) of the Hellenistic seven metals, Pliny the Elder's Natural History Book 34 chapters 156-164 of the 1st century, the plumbarius water pipes of Rome of the 1st century, the primal heavy matter of medieval alchemy, the addition of tetraethyl lead in 1922, and the introduction of unleaded gasoline in 1976.
