♁

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

(Christianity, astronomy): A globus cruciger (the globe surmounted by a Christian cross), representing God'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, the planet most similar to Earth.

♁

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

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