Tarot and astrology, mapped.

Tarot and astrology are usually taught as separate disciplines. They are not, in any working sense, separate. Since the Hermetic Order of the Golden Dawn formalised a unified correspondence system in the late 1880s — Mathers, Westcott, and the Cipher Manuscripts — every card in a tarot deck has had a specific astrological assignment. The Major Arcana map to planets and signs. The four suits map to the four elements. The numbered Minor Arcana map to the 36 decans of the zodiac. The court cards map to elemental modalities.

This essay lays out the full correspondence table and then shows what to do with it. The map is not a curiosity — it is the bridge that lets a reader use their natal chart to read a tarot pull and vice versa. The Cosmos Daily tarot engine is built directly on top of this correspondence system; reading the map below is essentially reading the schema.

The 22 Major Arcana and their rulerships

A few notes on this table. Three Majors carry a planet that didn't exist when the original system was set: The Fool (Uranus, discovered 1781), The Hanged Man (Neptune, 1846), and Judgement (Pluto, 1930). In strict Golden Dawn practice these cards were ruled by their element alone (Air, Water, Fire respectively). Most modern readers and decks use the outer-planet rulerships shown above, though both are defensible. The other 19 Majors have stable rulerships dating to the Hermetic tradition.

The four suits and the four elements

The Minor Arcana suits map cleanly:

• Cups = Water. Emotion, relationship, the inner life. Corresponds to the Water signs Cancer, Scorpio, Pisces.
• Pentacles = Earth. Body, money, material reality. Corresponds to the Earth signs Taurus, Virgo, Capricorn.
• Swords = Air. Mind, conflict, decision. Corresponds to the Air signs Gemini, Libra, Aquarius.
• Wands = Fire. Will, action, creative drive. Corresponds to the Fire signs Aries, Leo, Sagittarius.

This is why a tarot reading dominated by one suit reads differently from a balanced reading. A spread heavy in Cups is an emotional reading; a spread heavy in Swords is an analytical or conflictual reading; and so on. The same diagnostic move works in astrology — a chart heavy in Water is a different chart from one heavy in Air.

The 36 minor pip cards and the decans

This is where the correspondence system becomes specific. Each sign of the zodiac is divided into three decans of 10° each. The 12 signs × 3 decans = 36 decans, and the 36 numbered pip cards (Two through Ten in each of the four suits) correspond to them exactly. Each decan is also ruled by one of the seven classical planets in a recurring 7-card cycle through the zodiac, and each pip card inherits that planetary rulership.

Here is a partial example:

The full 36-card table appears in Aleister Crowley's Book of Thoth (1944), in Mathers's T Document from the original Golden Dawn papers, and in most modern tarot textbooks. The practical use is this: if your transiting Sun is at 17° Aries, the Three of Wands is your active pip card today. If a tarot reading turns up the Three of Wands and you are an Aries Sun person, the card is amplified — it is hitting your own decan.

Court cards and modalities

The 16 court cards (Page, Knight, Queen, King × 4 suits) correspond to a combination of element and modality:

• Kings are the cardinal expression of their suit's element — initiating, authoritative, established. King of Wands = Fire of Fire = the boldest form of fire.
• Queens are the fixed expression — sustaining, holding, integrating. Queen of Cups = Water of Water = the deepest still water.
• Knights are the mutable expression — moving, acting, changing. Knight of Swords = Air in motion = the gust that arrives suddenly.
• Pages are the nascent or beginner expression — apprentice, learner, new energy. Page of Pentacles = Earth at its start = the first piece of practical knowledge.

The Golden Dawn system pushed this further by assigning each court card a 30° arc of the zodiac spanning the last decan of one sign and the first two of the next. This is technical enough that most working readers ignore it day-to-day, but it is part of why a single court card can describe both a specific person (a Capricorn–Aquarius cusp person, say) and a more general energy.

What this lets you do

The correspondence map turns tarot and astrology into a single vocabulary. A few of the most useful moves:

Read your transits as tarot. If Saturn is currently transiting your natal Sun, the card of that transit is The World on Sun — Saturn-ruled completion landing on your vitality. The transit is "finishing something solar in your life". The tarot card gives the transit a face.

Read a tarot pull through your chart. If you draw The Tower in a reading and your natal Mars is in Aries, the card is doubly Mars-loaded — your already-Mars-prominent chart is being asked to deal with the archetype of Mars-as-collapse. A weaker-Mars chart drawing the same card reads it differently: the card is bringing in an energy that is otherwise absent.

Use tarot to study an astrological placement. Pulling the Major Arcana card for a planet (Mercury → Magician, Venus → Empress, etc.) and meditating on it is a faster way to feel the planet's archetype than reading three textbooks. The Major Arcana exist partly because the medieval and Renaissance traditions wanted iconographic shorthands for the planetary forces.

Use astrology to interpret a difficult tarot card. If you cannot tell whether the Devil card is showing up as restrictive or as creatively binding in your reading, ask which Capricorn placement in your chart it is naming. Reading the card through your specific Capricorn condition (Sun? Saturn? 10th house?) collapses the ambiguity.

The history in one paragraph

The systematic tarot-astrology correspondence is not ancient. The Egyptian and Hebrew claims made by Court de Gébelin in 1781 and by Éliphas Lévi in the 1850s were retrojective fantasies — they imagined a unified system existed and tried to reconstruct it. The actual unified system was synthesised by the Hermetic Order of the Golden Dawn in London in the 1880s, drawing on Lévi's framework, the Kabbalistic Tree of Life, classical planetary rulerships, and the medieval decan system. The synthesis was first published openly by Aleister Crowley in the 1944 Book of Thoth, though it had been circulating among initiates since the 1890s. The Rider-Waite-Smith deck (1909) embedded the system visually but did not name it on the cards; readers had to learn the correspondences from accompanying texts.

"Each card is a partial map of a single chamber of the same vast palace. Astrology, tarot, the Tree — they are not different traditions but different doors into the same room." — Israel Regardie, The Golden Dawn, 1937

Once you know the map, the two practices stop feeling separate. A tarot reading is an astrological consultation in archetypal language. An astrological transit is a tarot pull you did not have to shuffle. The Cosmos Daily reading engine treats them this way by default: every card we draw for you is cross-referenced against your full natal chart, and every transit you live through has a card you can pull to feel its texture.
