Tarot reading is a subset of Cartomancy, which is the belief in using cards to gain insight into the past, current and future situations by posing a question to the cards. Variations on the reasons for such belief range from believing on guidance by a spiritual force, to belief that the cards are but instruments used to tap either into a
collective unconscious or into 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.
