Oswald Wirth is the last and greatest author of the French School of Tarot. Strength is XI and Justice is VIII, but more than anything the Tarot of Wirth expresses the powerful symbolic depth of each Arcana - even the Minors - through the system of the Tetrads, as built by Wirth itself and developed by Italian scholar Mirko Negri. Oswald Wirth, Mirko Negri, Bruno Letizia, 78 cards, 66x120 mm. Instructions. Multilingual edition.
