Correspondences of Mercury

the classical correspondences of Mercury: day, metal, colour, incense, angel and deva

What the tradition reads

The grimoire tradition gives Mercury Wednesday as its day, the day the Heptameron's own working text assigns to this planet's operations, and quicksilver as its metal, correspondences Agrippa's Scale of the Number Seven records. Agrippa's separate chapter on planetary colours gives Mercury no colour of its own, grouping it instead with Venus and the Moon under one shared set, all white, fair, curious, green and ruddy, between saffron and purple, while his chapter on planetary fumes gives Mercury a suffumigation of mastick, frankincense, cloves and the herb cinquefoil, with the stone achates, none of it a poisonous substance. Agrippa's own Scale of the Number Seven gives Mercury the angel Michael, while the Heptameron's working text names a different angel, Raphael, for Wednesday, a mirror image of the very disagreement this corpus already records for the Sun, where Agrippa's Scale gives Raphael and the Heptameron gives Michael to Sunday instead, the same two names simply swapped between the two offices. The Vedic tradition names its own significator for the same planet, Budha, a graha the tradition reads as gentle, quick witted and mild, governing speech, trade, wit and travel, whose colour is green and whose own day, Wednesday, called Budhavara, matches the Western tradition's day for this planet exactly.

The story

Mercury's correspondences descend through the same sixteenth century synthesis as every other planet's, Agrippa's Three Books of Occult Philosophy and its Scale of the Number Seven, drawing older astrological material into one systematic table. The planet's Roman name preserves the god Mercury, messenger of the gods and patron of trade, travel and eloquence, an office the Greek tradition gave to Hermes, and the astrological planet keeps that quickness and versatility directly in its correspondences, quicksilver a metal that flows and will not hold one shape, fitting a planet the tradition reads as changeable by nature, taking on the character of whatever planet stands nearest it. The Heptameron's working text names Raphael as Wednesday's angel where Agrippa's Scale names Michael instead, an inversion of the Sun's own pairing of these same two names that later occultists, recording both grimoire lineages faithfully, generally kept rather than resolved. Budha's own Vedic myth gives the planet a more troubled origin: Wikipedia's account of the deity names Budha's father as Chandra, the Moon, and his mother as Tara, a parentage the wider mythology treats as a genuinely difficult one rather than smoothing it into a simple lineage.
