• Ƶ

The Greek letter Zeta with an abbreviation stroke, for Ζεύς (Zeús), the Greek equivalent to the Roman god Jupiter.^[1] The form changed from Classical and early Medieval ⟨Ƶ⟩ to one with a more salient cross, ⟨♃⟩, in the 15th–16th century, at about the time that Christian crosses were added to ⟨☿⟩, ⟨♀⟩ and ⟨♄⟩, and so may have had a similar motivation.

   • May 18 Ideam solutionis perfeci Nempe æqualia duo salia elevant ♄ Dein hic elevat lapidem, nec non cum Iove malleabili conjunctus fit 🝏 idque in tali proportione ut ♃ sceptrum apprehendat. Tunc aquila ♃em attollet., Isaac Newton, Cambridge, Portsmouth Add. MS. 3975 (alchemical notebook):

     (please add the primary text of this quotation)

     May 18 I came up with an idea of the solution, namely, two equal salts elevate Saturn, then this elevates the stone, and also conjoined with malleable Jove it becomes the scepter of Jove and this in such a proportion that Jupiter seizes the scepter. Then the eagle raises up Jupiter.
