The paradox of the Italian Renaissance was that it was a time of extraordinary artistic creativity, yet art of the High Renaissance was created during a period of intense political turmoil.
Around 1481–82 Leonardo da Vinci wrote an extraordinary letter offering his services to the Duke of Milan.
This is the secretarial draft of that letter.
In it the artist describes many types of weapons, siege machinery, portable bridges, hydraulic devices, and other engineering innovations he can create for the Duke of Milan.
Only at the very end of the letter does he mention his painting.
Leonardo’s designs for various inventions in the Atlanticus Codex in the Biblioteca Ambrosiana.
Leonardo was a man of genius, whose life was full of contradictions.
