Tarot cards come in many different designs and the Major Arcana goes all the way back to 1440. The first deck was found in Italy and they were thought of as being the forefathers that are available as cards today. There are rumours that say that tarot cards were originally created to keep nobles entertained but after a period of time, they soon became a tool of divination. The first account of this was by Jean-Baptiste Alliette and he was the first member to ever publish meanings for these cards. There were only 32 cards included in this and in the 19th century, Eliphas Levi developed a correlation between the Kabbalah and the Tarot. This created a Hebrew mysticism and this brought around an entirely new belief. People thought that the Tarot originated in Israel all along, and that it contained wisdom that would then correspond to the Tree of Life. This theory joined all 78 cards together and this alone showed that the Tarot would cross all boundaries.
Today, Tarot cards are designed to reflect trends in religion, sexuality, culture and philosophy but this wasn't always the case, as you can see from above. In fact, at the moment, there are hundreds of different interpretations and this means that the person who is reading the cards can choose a deck that is similar to their personality and their own reading style. There are decks that have a more serious tone and there are even decks that correspond to dream-like features.
When a card is read, it gives you an insight to who you are and what you could achieve in the future, so you can already start to see how deep this goes and how it could be interpreted based in numerous religions and beliefs.
