Waite–Smith, Wands
Knight of Wands

What you can see
A rider holds a short leafy staff as the horse lifts its forelegs. Pointed hills stand behind the moving pair.
What Waite says
Waite treats the horse’s movement as a clue to the rider’s precipitancy. The account concerns departure and changes of residence, while explicitly saying that the journey is not a warlike errand.
Waite · Part III, §2 · printed p. 174 ↗In the Thoth deck
Waite’s courts are King, Queen, Knight and Page. Thoth has Knight, Queen, Prince and Princess, so a rank does not carry straight across. See both ways to match them.
