Tarot wiki
This is the background layer — where the cards came from, who built the systems people read today, and how deck structure has changed over time. If you want practical reading help instead, start with Learn Tarot or Tarot Traditions.
These articles separate documented history from what a tradition teaches about itself — dates and authorship are sourced to museums, publishers, and primary texts; symbolic and esoteric claims are described as belief, not verified fact.
