The King of Pentacles is depicted in a black robe decorated with grapes and vine leaves over his armor; sitting upon a throne decorated with carvings of bulls and vine-leaves. Beneath and around him there are grapevines, flowers, and other plants; surrounding him and his throne; even his crown is garnished with flowers. The King of Pentacles holds his staff in his right hand and a pentacle in his left hand. In the background, a large castle is visible.
The grapes and leaves on the King’s robe suggest that the King of Pentacles has grown to the vitality and abundance he enjoys today from exiguity. In other words, he has fought tooth and claw to manifest his ideas and realize his aspirations. The armor beneath the robe strengthens this symbolism, implying that the King is still ready to get his teeth into another if that is necessary to protect the prosperity of his Kingdom. The plants surrounding the King and his throne stand for the attainment of material aspirations at the highest level. This attainment is procured by the King’s (will)power, represented by the staff in his right hand; and by the influence secured by this willpower, represented by the pentacle in his left hand. The castle in the background represents the security and the accumulation of wealth.
