Abstract
One of the factors that certify Delacroix's eminence as the pivotal figure in the history of nineteenth century French painting is in essence technical: he liberated, once and forever it would seem, the free movement of paint on the surface of the canvas from the tight control of the academic brush which denied painterly texture a role in the vocabulary of art. It is characteristic of Delacroix that this act of liberation was neither an arbitrary overflow of romantic exuberance nor a revolutionary device completely lacking in precedent, theoretical and practical. Moreover, he was eloquently articulate on the subject, so that his aims and theoretical sources are abundantly clear.
