Tarot reading is belief in using cards to gain insight into the past, current and future situations by posing a question to the cards, i.e. cartomancy. Some believe they are guided by a spiritual force, while others believe the cards help them tap into a collective unconscious or their own creative, brainstorming subconscious. The divinatory meanings of the cards commonly used today are derived mostly from cartomancer Jean-Baptiste Alliette (also known as Etteilla) and Mlle Marie-Anne Adelaide Lenormand (1776-1843). The belief in the divinatory meaning of the cards is closely associated with a belief in their occult, divine, and mystical properties: a belief constructed in the 18th century by prominent Protestant clerics and freemasons.
