Miscellaneous Symbols

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.

Symbol

  1. (astronomy) the planet Earth.
  2. (Christianity) the redeemed world (a symbol that was carried by depictions of Jesus and medieval Christian kings).
  3. (cartography) marks a church.
  4. (alchemy) stibnite (antimony ore, Sb2S3).
  5. (astrology, rare) the fictitious planet Proserpina, which one Polish school of astrology identifies as the dwarf planet Eris.

Usage notes

In contemporary astronomy, ⟨♁⟩ is particularly common in German-language sources. 🜨 is the usual symbol in English-language sources, but ⟨♁⟩ also occurs.[1]
