EXAMPLES OF EARLY ITALIAN TREATMENT OF TREES
A. From pictures in Oratorio di S. Ansano. "Il trionfo dell' Amore," attributed to Botticelli.
B. From "L'Annunziazione," by Botticelli, Uffizi, Florence.
C. From "La Vergine," by Giovanni Bellini in the Accademia, Venice.
Corot in his later work developed a treatment that has been largely followed since. Looking at trees with a very wide focus, he ignored individual leaves, and resolved them into masses of tone, here lost and here found more sharply against the sky. The subordinate masses of foliage within these main boundaries are treated in the same way, resolved into masses of infinitely varying edges. This play, this lost-and-foundness at his edges is one of the great distinguishing charms of Corot's trees. When they have been painted from this mass point of view, a suggestion of a few leaves here and a bough there may be indicated, coming sharply against the sky, but you will find this basis of tone music, this crescendo and diminuendo throughout all his later work (see illustration, page 215 [Transcribers Note: [Diagram XXVI]]).
These are three of the more extreme types of trees to be met with in art, but the variations on these types are very numerous. Whatever treatment you adopt, the tree must be considered as a whole, and some rhythmic form related to this large impression selected. And this applies to all forms with serrated edges: some large order must be found to which the fussiness of the edges must conform.
The subject of edges generally is a very important one, and one much more worried over by a master than by the average student. It is interesting to note how all the great painters have begun with a hard manner, with edges of little variety, from which they have gradually developed a looser manner, learning to master the difficulties of design that hard contours insist on your facing, and only when this is thoroughly mastered letting themselves develop freely this play on the edges, this looser handling.
