Planets in SignsMercury in Aquarius: What It Means in a Birth Chart
Mercury governs thinking, speaking and learning, and Aquarius is an air sign in fixed mode. Here is what the placement does, its shadow, and the real dates Mercury is in Aquarius.

The Six of Swords means leaving, transition, toward better. What it means upright and reversed, the four ways readers handle reversals, and the Mercury in Aquarius attribution behind it.

Pamela Colman Smith drew the Six of Swords as a ferryman poling a flat boat with six swords standing upright in it and two hunched passengers, choppy water behind and still water ahead. That matters more here than in the Majors. Before 1909 the pip cards of almost every deck showed nothing but an arrangement of cups or coins, and you had to have memorised a meaning to read one. She gave all forty of them a scene, and that single decision is why a beginner can read this deck at all.
Leaving, with difficulty, toward somewhere better. Nobody in the boat looks happy and they are all still going.
Swords are the thinking suit, and the most uncomfortable of the four. They are about what is being said, decided or avoided rather than what is being felt. The question the card puts to you: what you are taking with you.
| If the question is about | The Six of Swords upright | What to check |
|---|---|---|
| Love | Moving on, mid-process. | Which other suits are on the table |
| Work | A transition already underway. | Whether the position is past, present or advice |
| Money | A necessary and unglamorous move. | Whether the surrounding cards agree with it |
Being unable to go, or going nowhere different.
Readers disagree about how reversals work, and the disagreement is not minor: the four common methods give four different answers for the same card. Any page that gives you one reversed meaning and does not mention this is simplifying.
| Method | What the reversal means | When it fits best |
|---|---|---|
| Blocked or delayed | The upright meaning, not available yet | The most common method. Works on almost any card |
| The opposite | The reverse of the upright meaning | Cards with a clear opposite, like the Sun or the Ten of Cups |
| Turned inward | The upright meaning, happening privately | The feeling cards, and most of the Cups |
| Too much of it | The upright quality in excess | The strong cards: Strength, the Emperor, the King of Wands |
The Six of Swords is given the second decan of Aquarius, which is the stretch from 10 to 20 degrees of the sign, ruled by Mercury. That is not decoration. The thirty-six pip cards from Two to Ten map onto the thirty-six decans in order, and the ruler of each decan comes from the Chaldean sequence counting forward from the first third of Aries. So the card and the placement are describing the same thing twice: Mercury in Aquarius is the Six of Swords in a birth chart.
| Field | Value |
|---|---|
| Suit | Swords (Air) |
| Decan | second decan of Aquarius |
| Degrees | 10 to 20 degrees of Aquarius |
| Ruled by | Mercury |
| Reads as | Mercury in Aquarius |
This is the part that almost no tarot page prints, and it is the part that makes the deck make sense. The seventy-eight cards are not seventy-eight separate ideas. They are four elements, ten numbers, four court ranks and twenty-two Majors, laid over the zodiac in a fixed order. Once you can see the structure you stop needing to memorise anything.
Swords are the thinking suit, and the most uncomfortable of the four. They are about what is being said, decided or avoided rather than what is being felt. Swords are the Air suit and they govern thought, words, conflict and truth. The suit's three signs are Libra, Aquarius, Gemini, in that order: cardinal, fixed, mutable. The Twos, Threes and Fours sit in the first of those, the Fives, Sixes and Sevens in the second, the Eights, Nines and Tens in the third. That is the whole system for the pip cards.
The Eight of Cups. The Eight is choosing to leave. The Six is the leaving itself.
Worth knowing, because most pages present card meanings as though they were handed down from antiquity. Playing cards reached Europe in the fourteenth century and the earliest surviving tarot decks were painted in northern Italy in the fifteenth, as a card game. For roughly three hundred years that is all they were. Divination with them is first clearly documented in the late eighteenth century, in France.
The meanings in use today in English are almost entirely the Rider deck's. It was published in London in 1909: Arthur Edward Waite wrote the scheme, Pamela Colman Smith drew all seventy-eight cards, and she was paid a flat fee and went uncredited on the box for most of a century. Her decision to give every pip card a scene rather than a plain arrangement of symbols is the single reason modern tarot works the way it does, because a picture can be read by somebody who has memorised nothing.
Both of them were members of the Hermetic Order of the Golden Dawn, which is where the astrological attributions on this page come from. Those are a genuine system with internal logic, and they are a little over a century old rather than ancient. Saying so costs nothing and it is the difference between a page you can trust on the rest of the detail and a page you cannot.
The deck is the same deck for everybody who picks it up, which is both the appeal and the limit. A birth chart is not shared with anybody: it needs your date, your time and your place. If you do not know your birth time, this covers how to find it.
The Six of Swords means leaving, transition, toward better.
Readers use four different methods for reversals: blocked, opposite, turned inward, or too much of it. The article sets out all four, because they give different answers and no single one is the correct reading.
Mercury in Aquarius, in the Golden Dawn system the Rider deck was built on.
No. A card describes a situation and asks a question about it. Nothing in the tradition names a date, and nothing in it should stand in for medical, legal or financial advice.
