Chlorine
Chlorine is element number 17 on the periodic table — a Halogen, atomic weight 35.45. On Matter it is read not only as chemistry but through four interpretive lenses. The science below is cited as science; the symbolic layers are flagged as interactive art.
Discovery
Carl Wilhelm Scheele — produced from HCl + MnO₂; recognized as element by Davy in 1810 · Sweden · 1774
Stellar origin cited science
Supernova explosive oxygen-burning
Built during the violent oxygen-burning shell-flash and released to the interstellar medium when the star explodes.
Musical key interactive art
Periodic Frequency maps atomic number 17 to Camelot seat 12B · E Major. A deterministic, octave-reduced mapping — musically usable, not a literal claim about atomic vibration.
Curiosity
Yellow-green gas that killed soldiers in WWI's Ypres trenches and now keeps swimming pools safe — same chemistry, different dose.
An interpretive reading. The nuclear and stellar science (origins, body composition, discovery) is cited as established science; the symbolic layers — the Camelot musical key and the scriptural shadow — are contemplative art, interpretive readings, not literal claims. Testimony, not prediction.
