Make your own theory
Before you peek, what do you think the clues show?
Write or discuss an explanation in your own words. Then compare it with the sourced case note below. This preview doesn’t save responses.
What a careful answer can say: A supported account can say the notebooks use right-to-left mirror script and that the reason is debated. This keeps observation distinct from explanation.
What the evidence cannot settle: The museum description does not settle why Leonardo used mirror-writing. Do not turn an open interpretation into a quotation or a fact.
