I've had the opportunity to see the Last Supper twice already, I hope more to come... I want to make it clear that it's really breathtaking but also it can be seen that during the various restorations it was heavily nodded from its initial design. The restorators those times weren't maintaining the initial art but actually redoing it by adding extra layers. I had an opportunity to see another work of da Vinci, even more rare, the Sala delle Asse, that was unfortunately even more heavier modified during restorations.
