Wheel of Fortune and The Moon

Two cards of cycle, and the Moon is the one that actually is one. The tradition reads the pair as a recurrence rather than a change: this has happened before, on a period long enough that it was not recognised as a pattern.

Associated with a difficulty returning on a cycle. The pair suggests looking back further than feels necessary.

Read for a recurring situation being met as though it were new. The pair notes the record would show otherwise.

Look further back. This is a phase rather than an event, and the length of the cycle is what has hidden it.
