“When mastering drapery drawings in Verrocchio's studio, Leonardo also pioneered sfumato, the technique of blurring contours and edges. It is a way for artists to render objects as they appear to our eye rather than with sharp contours. This advance caused Vasari to proclaim Leonardo the inventor of the 'modern manner' in painting, and the art historian Ernst Gombrich called sfumato 'Leonardo's famous invention, the blurred outline and mellowed colors that allow one form to merge with another and always leave something to our imagination.' The term 'sfumato' derives from the Italian word for 'smoke,' or more precisely the dissipation and gradual vanishing of smoke into thin air . . . With no sharp lines, enigmatic glances and smiles can flicker mysteriously.” ArtPaintingTechniqueDrawingsSfumato Book:Leonardo da Vinci Source: Leonardo da Vinci
“That’s quite all right,” I said. Sfumato, that was what the painters called it; a blurring or elision of the lines, the kind Leonardo had used to give his Mona Lisa her beguiling flux.” ArtBlurMona LisaSfumatoLeonoardo Author:Paul Murray
