Waite–Smith, Pentacles
Knight of Pentacles

What you can see
An armoured rider holds a pentacle while seated on a heavy, stationary-looking horse. Parallel field lines run behind them.
What Waite says
Waite describes endurance, utility and responsibility. His reversed account includes stagnation and inertia, making the quality of steadiness something to examine rather than praise automatically.
Waite · Part III, §2 · printed p. 258 ↗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.
