The most important recipes of Cennino Cennini may be those which relate to fresco-painting; and as that is now likely to be nationally revived, this publication is well-timed. So much has been said and written of late upon this subject, that we think it best simply to refer to the text and notes. To those who mean to practise fresco, they may be important. Besides the value of the recipes of Cennino, there are incidentally some curious things not unworthy of notice. All persons must have been surprised in pictures of grave subjects, and we might especially mention those of Paul Veronese, that dogs are introduced as attendants on feasts, and we find them gnawing bones on very fine floors. But we find in Cennino Cennini that it was the practice to throw their bones under the table. Cennino recommends them to be gathered and selected for black pigments. We have heard it said that Murillo was partial to the pigments made from beef bones taken after dinner.
There is a practice, or we should say happily there was, in the days of these old painters, which did not tend very much to raise the profession. "Sometimes, in the course of your practice," says Cennino, "you will be obliged to paint flesh, especially faces of men and women." He recommends the painting them with egg tempera, with oil, and with _oil and liquid varnish_, "which is the most powerful of temperas." He proceeds to tell how the paint is to be removed. Chapter 162 is entirely devoted to the ladies, and offers a caution now happily unnecessary, but it is so quaintly given, that we quote it:--
"It sometimes happens that young ladies, especially those of Florence, endeavour to heighten their beauty by the application of colours and medicated waters to the skin. But as women who fear God do not make use of these things, and as I do not wish to render myself obnoxious to them, or to incur the displeasure of God and our Lady, I shall say no more on this subject. But I advise you, that if you desire to preserve your complexion for a long period, to wash yourself with water from the fountains, rivers, or wells; and I warn you, that if you use cosmetics, your face will soon become withered, your teeth black, and you will become old before the natural course of time, and be the ugliest object possible. This is quite sufficient to say on this subject."
