This might be a good place to post this picture of Duquette's diagram from
Tarot of Ceremonial Magick. LRichard's is a nice compliment to it, filling in stuff Duquette left out.
Chart
A few things to note about the DuQuette diagram:
The Aces and Princesses each span three signs. For example, the Ace and Princess of Discs spans Aries, Taurus, and Gemini. This is the season of spring. The other Aces and Princesses of Wands, Cups, Swords span Summer, Fall, Winter, respectively (northern hemisphere).
The other court cards each span three decans: the first two decans of their primary sign and the last decan of the previous sign. For example, the Queen of Swords spans the first two decans of Libra (Justice, Cardinal Air) and the last decan of Virgo (Hermit). A couple things to note:
The courts preside over the transitions from one sign to the next.
The Queens are primarily Cardinal, Princes (the Waite Kings) primarily Fixed, and Knights primarily Mutable.
