the entire Tarot deck is a quincunx with the four minor suits in the four corners and the Major Arcana in the center. It is like a sacred mandala and its entire structure is illustrated by the Marseilles World card.
Place explicitly identifies the complete Tarot as a quincunx mandala, asserting that its fourfold minor structure surrounding a central Major Arcana replicates the sacred geometry of the mandala form.
