Planetary Magic: Seven Metals, Seven Days, and the Stars That Shaped Ritual

In Western magic, the seven classical planets — Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon — aren't just celestial bodies. They're fundamental forces that structure reality. Every day of the week, every metal, every color, every gemstone, every tarot card, every Hebrew letter, every Sefirah on the Tree of Life is connected to one of these seven. The system of correspondences is the operating manual of Western ceremonial magic.

The seven planets were all that pre-telescopic astronomy could see moving across the sky — the "wandering stars." They were named after gods, and the gods' attributes were mapped onto their cosmic influence. The system was formalized in Hellenistic astrology, inherited by Arabic astrology, and codified in European occultism by Cornelius Agrippa in his Three Books of Occult Philosophy (1533).

The seven planets and their correspondences

*Jupiter and Venus share Friday in some systems, but Friday is traditionally Venus's day. Jupiter's day is Thursday in the standard system. The order from highest to lowest sphere is: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon.

How the system works

The planetary system operates on a principle of sympathy — the idea that things connected by correspondence influence each other. If you want to work with Venusian energy (love, beauty, harmony), you'd choose Friday, use copper or emerald, work with the color green or pink, and invoke Venus's divine names. The ritual elements reinforce each other through their shared connection to the planet.

Agrippa's Three Books of Occult Philosophy organized this into a massive table of "occult signatures" — every plant, animal, mineral, gemstone, star constellation, and even body parts were assigned to planets. This created a searchable database of correspondences that practitioners could consult when designing rituals.

Planetary hours

Planetary hours are a timing system that assigns each hour of every day to one of the seven planets. The system works like this:

• Divide daylight (sunrise to sunset) into 12 equal "hours" — these are variable-length, not clock hours
• Divide nighttime (sunset to sunrise) into 12 equal "hours" the same way
• Assign the first hour of each day to the ruling planet of that day (Sunday = Sun, Monday = Moon, etc.)
• Count backward through the planetary order (Moon → Mercury → Venus → Sun → Mars → Jupiter → Saturn) to assign each subsequent hour

This means each planet rules four hours on every day, plus the entire day that bears its name. A Venus ritual should ideally be performed during a Venus hour on a Friday — the most Venus-dominant time possible. Planetary hour calculators are widely available online.

Talisman making

A planetary talisman is a physical object — typically a metal disc — inscribed with symbols corresponding to a specific planet, created during that planet's hour and day. The basic procedure from the Key of Solomon:

1. Choose the planet based on your goal (e.g., Jupiter for abundance and protection)
2. Cast or prepare the metal disc from the corresponding metal (tin for Jupiter)
3. Draw the planetary sigil, astrological glyph, associated zodiac sign, and divine names on the disc
4. Purify yourself and the workspace
5. Perform the invocation during the planetary hour
6. "Charge" the talisman by focusing intention and invoking the planet's force

The Golden Dawn system refined this by mapping each planet to specific Sefirot, paths, and elemental forces. Mars rules the path between Geburah and Netzach on the Tree of Life, for instance. The talisman becomes a microcosm of the entire planetary sphere.

The Golden Dawn's planetary system

The Golden Dawn went further than medieval planetary magic by integrating planets into their complete system of correspondences. Each planet was linked to:

• A specific grade in the order's curriculum
• Specific Major Arcana tarot cards (e.g., The Sun for the Sun)
• Elemental angels and governing spirits
• Specific incenses, candles, and vestment colors
• A planetary invocation ritual

The planetary invocation ritual involves calling the planetary intelligence, presenting the talisman, and asking for specific assistance. Israel Regardie's The Golden Dawn (1937) documents the complete ritual text.

Modern practice

Planetary magic remains one of the most accessible entry points into Western ceremonial practice. You don't need a temple or decades of training. You need a planetary hour calculator, some basic materials (metal, symbols, incense), and the Key of Solomon or Regardie's texts for the ritual structure.

The results — like all magic — depend on your interpretation. Practitioners report measurable effects: improved mood during Venus rituals, increased focus during Mercury work, heightened courage during Mars operations. Whether these come from planetary forces, focused intention, or the placebo effect is the perennial debate. Most serious practitioners conclude that the distinction doesn't matter if the results are consistent.
