Alchemical symbol

Alchemical symbols in Torbern Bergman's 1775 Dissertation on Elective Affinities

Alchemical symbols, originally devised as part of alchemy, were used to denote some elements and some compounds until the 18th century. Note that while notation like this was mostly standardized, style and symbol varied between alchemists, so this page lists the most common.

Three primes

According to Paracelsus (1493-1591), the three primes or tria prima are[1][2]

  • Salt (base matter)
  • Sulfur (omnipresent spirit of life)
  • Mercury (fluid connection between the High and the Low)

Four basic elements

Western alchemy makes use of the Hellenic elements. The symbols used for these are:[1]

Seven planetary metals

Seven metals are associated with the seven classical planets, and seven deities, all figuring heavily in alchemical symbolism. Although the metals occasionally have a glyph of their own, the planet's symbol is used most often, and the symbolic and mythological septenary is consistent with Western astrology. The planetary symbolism is limited to the seven wandering stars visible to the naked eye, and the extra-Saturnarian planets such as Neptune are not used.

The Monas Hieroglyphica is an alchemical symbol devised by John Dee as a combination of the planetary metal glyphs.

Mundane elements

"Squaring the circle": an alchemical glyph (17th century) of the creation of the philosopher's stone

Alchemical compounds

Alchemical processes

An extract and symbol key from Kenelm Digby's A Choice Collection of Rare Secrets, 1682

The alchemical magnum opus was sometimes expressed as a series of chemical operations. In cases where these numbered twelve, each could be assigned one of the Zodiac signs as a form of cryptography. The following example can be found in Pernety's 1758 Mytho-Hermetic Dictionary:[3]
