A 35-year hunt to uncover a lost work by Leonardo Da Vinci is reaching a climax in Florence, while also facing an angry protest by more than 100 prominent art historians who deplore the destructive but speculative work possibly leading to the masterpiece's uncovery.

If he didn’t see the country of his birth or his childhood friends soon, he never would.
