Core interpretation
Lightning opens the Tower in an instant. The fall is frightening, but it reveals the weakness already built into the structure and ends what could no longer stand.
A card carries more than one history. Its place in the tarot pack, Golden Dawn path, Rider–Waite–Smith reading and later variants are kept beside their own sources, since the same name can do different work in different decks.

Historical context
One of the twenty-one figured trumps plus the Fool found beside the four ordinary suits in historical tarot packs.
