Tarot decks did not come before decks having four suits of the same length. They were invented not for occult purposes but purely for gaming. In 1781, Court de Gébelin published an essay associating the cards with ancient wisdom. This idea was later disproved by Dummett. Tarot cards have been used for cartomancy and divination as well as gaming. Nowadays fortune-tellers tend to use specially-developed tarot decks rather than those used for games.
