Cartomancy
Cartomancy is divination performed through cards.
Cartomancy is a broad term covering practices that interpret selected or arranged cards in order to obtain guidance or information.
It can involve:
standard playing cards;
tarot;
or other card systems.
The V&A uses the term in its tarot history when describing Etteilla as a practitioner of cartomancy—that is, fortune-telling using cards—in the 18th century.
Not every reflective card practice needs to identify itself as cartomancy.
AngelCards.info uses random card selection primarily as a reflection system, while acknowledging the broader history of card divination.
