The first thing I often notice in a reading that includes Robin's "Knight of Pentacles" is the definite "heavy" feeling...the solid workhorse decorated with a whole lot of lavish cloths/armor and the Knight in full, weighty plate armor. And yet, neither the Knight nor the horse seem particularly burdened by all this stuff on them. In fact, they seem rather proud to be wearing such outerwear, representative of all they believe in and the lifestyle they've chosen to live. If need be, they could take off at a gallop and do what must be done...though they seem a twosome that truly abhors violence and does not stir up nor look for trouble. They are a team that can truly be depended upon. They will use well-thought-out common sense rather than rash and impulsive actions.
Since Pentacles represent to me, among other things, earth and body, the horse and Knight are characters who are FIRMLY grounded in the planet and protective of all that lives on it, just as the King and Queen of Pentacles are. But this Knight is young and virile and ready for anything...personal comfort is not in the forefront of this Knight's mind. This is a Knight who would be my idea of a "Knight in Shining Armor," as Robin also mentioned in her book. While the Knight of Wands may be more dashing and flamboyant, the Knight of Pentacles will be there when the battle is over, with no regrets, because he didn't act before he thought things out. And this Knight won't be hankering to be in battle all the time...he's perfectly content on the homefront.
Again, the colors of this card are peaceful and beautiful. The land is fertile and capable of growing whatever is needed. Like the Knight, even the land is ready to take on what's asked of it (if cared for well.)
I got a kick that Robin used artistic license and colored the horse's eyes green..."(not a color found on the real horse, I'm afraid)"...in order to be in keeping with "his correspondence with the earth and green growing things."
Robin's deck, in general, makes such wonderful use of color, plants, trees, metals, gems and more to symbolically help us to use her cards successfully in readings. I very much appreciate all the work and research she's put into making this incredible deck. It remains my favorite reading deck.
