Within Waite's four-rank court, the King of Coins heads the earth suit; in the Golden Dawn's Knight, Queen, Prince, Princess scheme the Thoth deck follows, the equivalent figure is the mounted Knight of Disks, assigned the elemental pairing Fire of Earth, material mastery expressed at its most active and forceful rather than earth's more settled Queen or Princess registers. His full Golden Dawn title, the Lord of the Wide and Fertile Land, and his astrological span, the final ten degrees of Aries through the first twenty of Taurus, frame the onset of Taurus's fixed earth, the sign the system most closely associates with settled material abundance.
Pamela Colman Smith's picture, a king enthroned amid carved bulls and grapevines, a coin in one hand and a scepter in the other, his robe embroidered with fruit, is a considerably richer composition than the Marseille Roi de Deniers, a static heraldic figure holding the suit emblem with no throne carving, vines or embroidery at all; the bulls specifically tie the image to Taurus more directly than any of the other three kings' thrones tie their figures to a single sign.
Crowley's Thoth card keeps the name Knight of Disks, showing him mounted and armored in a chariot drawn by a bull rather than seated, consistent with the deck's general shift of each suit's senior figure from a stationary ruler to an active, riding force.
