This book is really designed to be used with the Wizards Tarot by Corrine Kenner and John J. Blumen but it doesn't matter too much if you don't have a copy of that deck for three reasons.
1. All the cards are given as black and white illustrations on the relevant pages.
2. While the pictures in the Wizards Tarot deck are informed by the astrological associations that Corrine explains in the book, these associations are also present in many other tarot decks.
3. Corrine gives some very good explanations that help you understand and remember both the pictures and their meanings, so you can carry them over to whatever deck you prefer to use.
The associations themselves are based on the work done by the Golden Dawn to superimpose on medieval tarot cards Egyptian occultism, astrology, Qabalah and the Hebrew alphabet. As Corinne explains in the book, "Deck designers have been borrowing from and building upon each other's work for centuries."
She refers readers to Mystical Origins of the Tarot by Paul Huson but doesn't dwell on the background detail. She keeps her explanations very short and simple, summarising as follows:
"Arthur Edward Waite and Pamela Colman Smith borrowed from classical descriptions of the decans for their work on the Rider-Waite tarot; later, so did Aleister Crowley and Frieda Harris, who developed the Thoth tarot. In fact, both Waite and Crowley specifically designed their Minor Arcana cards to serve as a pictorial key to the astrological meanings of the cards."
That's true but whereas the decks derived from the Rider-Waite one have an intuitive feel, the decks that have sprung from the Thoth tarot stick more closely to the teachings of the Golden Dawn and tend to be more esoteric, which makes their symbolism harder to understand for the uninitiated. In a lot of these Thoth-inspired decks the references are overt but the meanings are obscure. For instance, you might see a card explained as "moon in cancer" (Four of Cups) or "mars rules, sun exalted (The Emperor)."
If you pick up a copy of The Book of Thoth by Aleister Crowley you will see cryptic sentences like this: "The background of this card shows the power of the planet Mars in his own sign Aries, the first of the Signs." That's for the Two of Wands.
Corrine Kenner de-mystifies this astrological shorthand and brings it to life in a way that is clear, approachable, easy to learn and easy to remember.
She introduces the astrological content gradually and gives some very clear background in a simple, direct way, without bogging you down in technicalities. I like the amount of detail she gives to the Minor Arcana and I have quoted above what she said about the decans because I think she explains them very well. This is in Chapter Six of the book, which is only a few pages but includes several helpful charts and diagrams to make the meaning clearer. She wears her learning very lightly but she has clearly researched the topic and her explanations are much more lucid and easier to follow than those I've read in other books.
A good example of how she elucidates the core ideas and works them into her own deck can be seen in the Four of Wands.
When Pamela Colman Smith was illustrating the cards she was working from guidelines provided by Arthur Edward Waite. He was higher up in the Order of the Golden Dawn than she was and had access to materials that she was not yet allowed to see. But Waite derived his descriptions from a manuscript called Book T, which includes a breakdown of the ruling planet and sign of the zodiac associated with each of the Minor Arcana.
The idea here is that you can divide a circle, which represents the heavens, into 12 segments of 30 degrees each and assign one of the 12 signs of the zodiac to each of them. Each segment can then be divided into three smaller segments of 10 degrees each, which are called decans. Starting with the first decan of Aries, you can then assign one of the seven planets from ancient astrology to each decan, in a fixed sequence of Mars, Sun, Venus, Mercury, Moon, Saturn, Jupiter. You end up with 36 sections, representing all the Minor Arcana (2-10 of each suit) each with a sign of the zodiac and a ruling planet.
For the four of wands we get venus in aries. The Thoth tarot labels this card "Completion" and includes the sign for venus at the top and the sign for aries at the bottom. In the centre is a wheel made of four red wands each with the ram of aries at one end and the dove of venus at the other. Between the spokes at the hub of the wheel are 8 tongues of flame.
In the Rider-Waite-Smith deck we see two robed figures, one in white and one in red, holding up garlands beneath a canopy of flowers, which is suspended on four staves firmly planted in the ground. Behind them is a turreted building, called a manor house by Waite, which can be reached by a bridge over a moat. Waite describes them as female figures but some people might see them as simply two people in what appears to be a wedding or celebration of some kind.
Many decks envision this card as a pairing of the Emperor and the Empress and of the solar and lunar forces, although the precise symbols used can differ widely.
Corrine's advice is to "imagine the Venusian Empress leaving her lush and fertile arboretum to visit the Emperor in his desert-like, Aries-influenced office." She depicts a man and a woman, both dressed in red, dancing between four staves topped with flaming torches. "Here in the Four of Wands," she says, "Venus aligns herself with the purpose-driven energy of Aries, and she teaches it to dance, so even though Venus is in its detriment in Aries" (i.e. 180 degrees away from her home on the other side of the zodiac, where she rules Libra) "the planet still manages to cast a romantic glow over an otherwise single-minded sign."
Her text is much more expansive than this and gives you plenty for your imagination to work with.
In general this is one of the more useful tarot books I own and it's presented in an attractive and very readable format. However, it's not perfect. It's a supplementary book in a way. It helps clarify and illuminate content that you may have come across in other books. Also, it is difficult to look things up. The table of contents is not comprehensive and there is no index. There is a lot of useful information scattered around and it can be difficult to find exactly what you are looking for sometimes.
If you already have The Wizards Tarot, this would complement it beautifully. If you don't have the deck, you may find some of the content, especially the descriptions of the images, helpful but not essential.
