8. The ‘people’ who wrote this was the sixteenth-century biographer of artists
Giorgio Vasari. Van Gogh derived his knowledge from
Jules Michelet,
L’amour, the start of book 5, chapter 4: ‘Vasari said a remarkable thing about the old master
Giotto, creator of Italian art: “The first thing he puts in the facial expressions is goodness.”’ (Vasari a dit un mot remarquable sur le vieux maître Giotto, créateur de l’art italien: “Dans l’expression des têtes, le premier il mit la bonté.”) (Michelet,
L’amour, p. 381). Cf. also Pabst 1988, p. 30.
