tactile values

tactile values.
Term coined by Bernard Berenson in his Florentine Painters of the Renaissance (1896) to describe those qualities in a painting that he regarded as stimulating the sense of touch. He thought that Giotto was the first master since classical antiquity whose painting demonstrated these qualities, which he considered to be a distinctive feature of Florentine painting and held to be ‘life enhancing’. His theories were not very cogent, and the term is now little used.
