Read the full account
On 10 December 1513 Machiavelli wrote to Francesco Vettori describing farm days and evening work on a small book of princely rule, the documentary date for The Prince’s composition. The letter is the instrument. Later print is 1532.
Context
A private letter later published is a knowledge-access and dating source. It is not yet a printed handbook of fear.
Niccolò Machiavelli is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Composition evidence is an initiating knowledge path. High confidence on the letter’s date in the received correspondence.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
