This is what we found on Wikipedia regarding the Tarot:

Tarot (, first known as trionfi and later as tarocchi or tarocks) is a pack of playing cards, used from at least the mid-15th century in various parts of Europe to play card games such as Tarocchini. From their Italian roots, tarot-playing cards spread to most of Europe, evolving into a family of games that includes German Grosstarok and modern games such as French Tarot and Austrian Königrufen. In the late 18th century French occultists made elaborate, but unsubstantiated, claims about their history and meaning, leading to the emergence of custom decks for use in divination via tarot card reading and cartomancy. Thus, there are two distinct types of tarot packs in circulation: those used for card games and those used for divination. However, some older patterns, such as the Tarot de Marseille, originally intended for playing card games, are also used for cartomancy.

Like the common playing cards, tarot has four suits that vary by region: French suits are used in western, central and eastern Europe, and Latin suits in southern Europe. Each suit has 14 cards: ten pip cards numbering from one (or Ace) to ten; and four face cards: King, Queen, Knight, and Jack/Knave/Page. In addition, and unlike standard packs, the tarot also has a separate 21-card trump suit and a single card known as the Fool. Depending on the game, the Fool may act as the top trump or may be played to avoid following suit. These tarot cards are still used throughout much of Europe to play conventional card games.
