Zang Huan on Leonardo da Vinci

"I once read somewhere that da Vinci is like a deep ocean, Michelangelo like a towering mountain, and Raphael like a boundless plain. On my last trip to Milan I was again on a journey to find the three 'greats' of the Renaissance, and again I felt that strength - like waves crashing in unison, but unable to move the great rock - from da Vinci's Last Supper. The painting is an immovable force within art history."
