Translingual

Alternative forms

(alchemy): 🜱 (for regulus of antimony / antimony metal)

Etymology

(Christianity, astronomy): A globus cruciger (the globe surmounted by a Christian cross), representing Christ's or the Church's rule over the redeemed world. Alchemical extension to newly-discovered antimony, motivated by an attempt to retain an association between the basic metals and the known planets. Astronomical use is reinforced by the graphic similarity to the symbol ⟨♀⟩ for Venus, which is the planet that is most similar to Earth.
