The Sun, from the Decameron deck.
I feel, to understand this deck, you must be willing to speak in the metaphor of sexuality, and then apply the message to your reading. For some, it seems a difficult jump to make... bridging the gap between the sexual act often depicted on these cards, and the divinatory knowledge they convey, is sometimes too difficult if they are challenged by what they see.
But, since this is one of my favorite decks, and I believe it deserves more study, I'd like to use it as an example here.
The card shows two figures lying on their sides, facing each other. One figure is leaning towards the groin area of the other, who has a look of rapture about his expression. He caresses the head of the leaning figure. The two are lying under a setting desert sun of pure white light. Yellow sand and scrub surrounds them, as well as their discarded armor and clothing. A lance is buried, as if in rest, in the ground behind the two.
What is not immediately noticable to most is that these are both young men who lay together.
The Little White Book, which I believe is the only one ever worth keeping, and mine is well wrinkled, says, "Affection and passion come from truth, not pretense. Everyone can find themselves in their nudity and can stop pretending."
These two have abandoned their "duties," as signfied by the discarded armor and weapons, and given themselves to what they feel inclined to express. They have shed themselves of pretenses, and "roles". This reminds me of the repressive wall of the RWS card. It is left behind.
They are giving and receving pleasure, and the card speaks of finding that place of abundance within, where one is bountiful enough to both give and receive easily (like the RWS child, who doesn't judge but opens his/her arms to us freely).
The fact that these are two young males speaks to this being an affection "born of equals." There may be a person involved in the Sun card that is seen as an equal, and/or one with whom you feel no need to "hide" who you are inside. Blessed is such a friendship.
