Best Paintings of all time

Never before or after did Leonardo da Vinci (1452-1519) used his technique of sfumato so well like in his painting 'Salvatore Mundi'. The slightly fogged portrait of Christ looks ethereal, phantasmagoric, and looking at it staring back at you, feels almost like a supernatural experience. That was his intention, and well, he achieved 100%. I guess this is my first favorite of Da Vinci, but then, this one is really something. It almost looks to good to be real. Truly a masterpiece from an artistic genious.
