Rules Gemini and Virgo · 5 decan cards
mind · speech · skill · trade
Mercury is the messenger, and its trump is The Magician: tools on the table, a hand raised to make thought real. It rules Gemini and Virgo, the airy and the earthy mind. Its decans include the Eight of Wands' swift news, the Three of Cups' good company and the Six of Swords' quiet passage. Where Mercury touches a card, words and skill decide things.

Mercurial cards favour learning, talking, writing and dealing. They also warn of cleverness running ahead of honesty.
Correspondences follow the Golden Dawn system the Rider–Waite–Smith deck was made within (tropical zodiac, dates approximate; they shift by a day in some years). Other traditions assign some cards differently. See the full table for all 78 cards.
