The move that actually happened
Leonardo da Vinci went to France in 1516, at the invitation of Francis I, and lived at the Château du Clos Lucé. He was accompanied by Francesco Melzi and his servant Battista Villanis. The château’s account of Leonardo’s life describes this final period.
Joining the French court is therefore not, by itself, an alternative history. The useful departure point is a different question: what if he had declined the move?
Change one decision
Keep the starting point in 1516. Choose an alternative place for Leonardo to live, then investigate what support and working conditions could plausibly have been available there. Do not introduce a different patron without checking the dates and circumstances.
A change of residence might alter the people he met or the work he prioritised. It does not establish that he would invent practical flight, prevent a war or initiate an industrial revolution. Those outcomes would need evidence about materials, knowledge, finance and other participants.
Build a defensible scenario
Divide your account into three parts:
- A documented baseline, including the real move and its date.
- A clearly labelled fictional decision to remain elsewhere.
- A short explanation of consequences you regard as plausible and those you cannot support.
Invented dialogue can bring a creative story to life, but it must not appear as a historical quotation. Likewise, sketches and imaginative designs should not automatically be described as functioning inventions.
A question to leave open
How much of a creative career depends on an individual, and how much on access to people, patronage and a place to work? Your scenario can explore that relationship without claiming to solve it.
