Mercury from "The Seven Planets with the Signs of the Zodiac", by Sebald Beham, 1539The planet Mercury

The Principles Of Astrological Geomancy

by Franz Hartmann, 1889.

Mercury represents the Intellect, and it may be a good or evil planet according to the conditions under which it acts. If ☿ is under the influence of ♄; that is to say, if the intellect is subservient to selfish and material things, it becomes a source of evil; if combined with ♃ it will produce pride; if united with love ?1 it will become wise, and in this manner “crude mercury” may be transformed into the gold of wisdom.

Mercury without love is said to rule especially those who live by their wits scrientific speculators, sophists, merchants, thieves, intellectual but not necessarily moral persons, men of letters, students, etc. In the mineral kingdom it is represented by quicksilver, in the spiritual realm by the god of trade.

Practical Astrology

by Comte C. de Saint-Germain, 1901.

Mercury is an unclassified planet, a sort of “free lance,” in the Astrological world. It is at times “friendly,” at others decidedly “inimical.” It all depends upon the aspect of the other planets toward it. Those born under Mercury — the Mercurians as they are called — are small in stature, but remarkable for their agility and bodily skill. Mentally, they are endowed with a versatility which renders them apt to undertake almost any study, trade, or pro- fession, and make a success of it. They remain young-looking very late in life and their complexion, rather of a creamy white, is often tinted by blushes. The hair is chestnut-colored and curls at the end; the forehead is high, the eyebrows meet, the eyes themselves are deep-set and penetrating, a little too restless, perhaps; the nose is straight, the upper lip protrudes slightly; the chin is long and pointed.

The Mercurians are active to a degree, fond of money-making and clever in business. Their voice is not strong and yet they are often eloquent, but of an eloquence that does not dazzle; it is of a convincing, not of a showy, style. They are born logicians and, on that account, are excellent mathematicians; they have wit, are quick at repartee and excel in turning a threatening failure into success. They are met most frequently among the professions, the medical particularly; they are successful in society and a Mercurian of the fair sex has always a crowd of fascinated admirers in her train when much handsomer women remain uncourted. In fact, adventurers of both sexes are, eight times out of ten, Mercurians, for they need a great deal of personal magnetism to victimize their dupes. Affected by Saturn, the Mercurian will become extremely dangerous, for he grows secretive, which Mercury is not by nature. Then all these talents for mischief may lead him to crime, such as forgery, perjury, even poisoning.

The defect against which all those born under Mercury ought to guard themselves with a tireless vigilance is a temptation to lie and an irresistible inclination to annex too freely other people’s property by schemes that are called “clever business devices” by the unscrupulous. Then again, they talk too much for the sake of boasting of their various feats of cleverness, and this weakness leads them into all manner of trouble.

Key of Solomon (Clavicula Salomonis)

~15th century; trans. and ed. by S. Liddell MacGregor Mathers, 1889.

  • The days and hours of Mercury are good to operate for eloquence and intelligence; promptitude in business; science and divination; wonders; apparitions; and answers regarding the future. Thou canst also operate under this Planet for thefts; writings; deceit; and merchandise.
  • The hours of Saturn, of Mars, and of the Moon are alike good for communicating and speaking with spirits; as those of Mercury are for recovering thefts by the means of spirits.
  • The hours of Mercury are good for undertaking experiments relating to games, raillery, jests, sports, and the like.
  • Furthermore, if thou wishest to converse with spirits it should be especially on the day of Mercury and in his hour, and let the Moon he in an airy sign2, as well as the Sun.

Bk. II Ch. XLIII Of the Images of Mercury.

From the operations of Mercury,

  • they made an Image at the hour of Mercury, Mercury ascending in Gemini, the form of which was an handsome young man, bearded, having in his left hand a rod in which a serpent is twyned about, in his right carrying a dart, having his feet winged; They report that this Image conferreth knowledge, eloquence, diligence in merchandizing and gain; moreover to beget peace and concord, and to cure feavers;
  • They made another Image of Mercury, Mercury ascending in Virgo, for good will, wit and memory; The form of which was a man sitting upon a chaire, or riding on a Peacock, having Eagles feet, and on his head a crest, and in his left hand holding a cock or fire.
Bk. 2 Ch LVIII Of the names of the Celestials, and their rule over this inferiour world, viz. Man.

The names of Celestiall souls are very many, and diverse according to their manifold power and vertue upon these inferior things, from whence they have received divers names, which the ancients in their hymnes and prayer made use of. Concerning which you must observe, that every one of these souls according to Orpheus’s Divinity, is said to have a double vertue; the one placed in knowing, the other in vivifying, and governing its body. Upon this account in the Celestiall spheres, Orpheus cals the former vertue Bacchus, the other a Muse. Hence he is not inebriated by any Bacchus, who hath not first been coupled to his Muse.

… in the sphere of Mercury, Silenus, and Euterpe

Bk 2 Ch LIX Of the seven governers of the world, the Planets, and of their various names serving to Magicall speeches.

Moreover they did call those governors of the world, (as Hermes calls them) Saturn, Jupiter, Mars, the Sun, Venus, Mercury, and the Moon, by many names, and epithites;

Mercury is called the son of Jupiter, the cryer of the gods, the interpreter of gods, Stilbon, the Serpent-bearer, the rod-bearer, winged on his feet, eloquent, bringer of gain, wise, rationall robust, stout, powerfull in good and evil, the notary of the Sun, the messenger of Jupiter, the messenger betwixt the supernall and infernall gods, male with males, female with females, most fruitfull in both sexes; and Lucan cals him the Arbitrator of the gods. He is also called Hermes i.e. interpreter, bringing to light all obscurity, and opening those things which are most secret.

Fourth Book of Occult Philosophy

trans. by Robert Turner, 1655.

The familiar forms to the Spirits of Mercury

The Spirits of Mercury will appear for the most part in a body of middle stature, cold, liquid and moist, fair, and with an affable speech; in a humane shape and form, like unto a Knight armed; of colour clear and bright. The motion of them is as it were silver-colored clouds. For their signe, they cause and bring horror and fear into him that calls them.

But their particular shapes are, A King riding upon a Bear. A fair Youth. A Woman holding a distaffe. A Dog. A Shee-bear. A Magpie. A Garment of sundry changeable colours. A Rod. A little Staffe.

The Mystical Hymns of Orpheus

by Thomas Taylor, 1824.



HERMES, draw near, and to my prayer incline,
Angel of Jove, and Maia’s son divine;
Studious of contests, ruler of mankind,
With heart almighty, and a prudent mind.
Celestial messenger, of various skill,
Whose powerful arts could watchful Argus kill:5
With winged feet, ‘tis thine through air to course,
O friend of man, and prophet of discourse:
Great life-supporter, to rejoice is thine,
In arts gymnastic, and in fraud divine:
With power endued all language to explain,
Of care the loosener, and the source of gain.
Whose hand contains of blameless peace the rod,
Corucian, blessed, profitable God;
Of various speech, whose aid in works we find,
And in necessities to mortals kind:
Dire weapon of the tongue, which men revere,
Be present, Hermes, and thy suppliant hear;
Assist my works, conclude my life with peace,
Give graceful speech, and me memory’s increase.



HERMES I call, whom Fate decrees to dwell
In the dire path which leads to deepest hell
O Bacchic Hermes, progeny divine
Of Dionysius, parent of the vine,
And of celestial Venus Paphian queen,
Dark eye-lashed Goddess of a lovely mien:
Who constant wanderest through the sacred feats
Where hell’s dread empress, Proserpine, retreats;
To wretched souls the leader of the way
When Fate decrees, to regions void of day:
Thine is the wand which causes sleep to fly,
Or lulls to slumberous rest the weary eye;
For Proserpine through Tartarus dark and wide
Gave thee forever flowing souls to guide.
Come, blessed power the sacrifice attend,
And grant our mystic works a happy end.

  1. A symbol which looks like Mercury’s (☿) but with a circle beneath; almost certainly intended rather to be that of Venus (♀). 

  2. or in an earthy sign, as hath been before said”, Add. MSS. 10862 & Aub. 24
    Later chapter 8 (concerning pentacles, and the manner of constructing them) has The pentacles should then be made in the days and hours of Mercury, when the Moon is in an aerial or terrestrial sign; she should also be in her increase, and in equal number of days with the Sun. This holds true for most of the Solomonic ritual implements. 

  3. A brittle variety of iron pyrite; before ~1845 it usually referred to iron pyrite itself, especially in the context of jewlery. It’s hard to say which is intended as either may have a silver luster. 

  4. The grimoiric wand material of choice, almost always harvested in the day and hour of Mercury (Wednesday at dawn). 

  5. That is, Argus Panoptes doing the dying. To free Io, Zeus had Argus slain by Hermes who, disguised as a shepherd, first put all of Argus’ eyes to sleep with spoken charms, then slew him by hitting him with a stone. Hermes was tried, exonerated, and earned the epithet Argeiphontes, “killer of Argos”.
