[Illustration: "UNA VILANA WENDISCH" Pen drawing with wash background in the collection of Mrs. Seymour _face_ p. 304] See the description in "Dürer's Schriftlicher Nachlass" (Lange und Fuhse), page 263, from which the above abstract is made. Sir Martin Conway continues: In these volumes Dürer is seen, sometimes writing under the influence of impetuous impulse, sometimes with leisurely care, allowing his pen to embroider the script with graceful marginal flourishes. At what period of his career Dürer first conceived the idea of writing a comprehensive work upon the theory and practice of art is unknown. It was certainly before the year 1512. The following list of chapters may perhaps be an early sketch of the plan. Ten things are contained in the little book. The first, the proportions of a young child. The second, proportions of a grown man. The third, proportions of a woman. The fourth, proportions of a horse. The fifth, something about architecture. The sixth, about an apparatus through which it can be shown that 'all things may be traced. The seventh, about light and shade. The eighth, about colours, how to paint like nature. The ninth, about the ordering (composition) of the picture. The tenth, about free painting, which alone is made by Imagination without any other help. III Glad enough should we be to attain unto great knowledge without toil, for nature has implanted in us the desire of knowing all things, thereby to discern a truth of all things. But our dull wit cannot come unto such perfectness of all art, truth, and wisdom. Yet are we not, therefore, shut out altogether from all arts. If we want to sharpen our reason by learning and to practise ourselves therein, having once found the right path we may, step by step, seek, learn, comprehend, and finally reach and attain unto something true. Wherefore, he that understandeth how to learn somewhat in his leisure time, whereby he may most certainly be enabled to honour God, and to do what is useful both for himself and others, that man doeth well; and we know that in this wise he will gain much experience in art and will be able to make known its truth for our good. It is right, therefore, for one man to teach another. He that joyfully doeth so, upon him shall much be bestowed by God, from whom we receive all things. He hath highest praise.
