Oracle cards and Tarot cards are similar in that they are both used for personal growth, inspiration, coaching, and divination.
Tarot cards are part of an ancient tradition of divination. The tarot, first known as trionfi and later as tarocchi, tarock, and others, is a pack of playing cards. Commonly it has 78 cards, which are used from the mid-15th century in various parts of Europe to play a group of card games such as Italian tarocchini and French tarot.
Divination using playing cards is recorded as early as 1540. A manuscript from 1750 (Pratesi Cartomancer) documents rudimentary divinatory meanings for the cards of the tarot. In 1765, Giacomo Casanova wrote in his diary that his Russian mistress frequently used a deck of cards for divination
Oracle cards are a modern version of tarot cards. They can range from a deck of less than a dozen to a deck of hundred cards. There is no traditional pattern or suits as such for the oracle cards. Oracle cards are also known as the Wisdom cards and are completely different from tarot cards.
Each oracle deck is different from the next in structure, the number of cards, and what cards are present.
