PEACHAM, Henry, The Compleat Gentleman: Fashioning Him absolute in the most Necessary and Commendable Qualities, concerning Mind, or Body, that may be required in a Person of Honor. To which is added the Gentlemans Exercise or, An exquisite practise, as well for drawing all manner of Beasts, as for making Colours, to be used in Painting, Limning, &c. The Third Impression much inlarged, especially in the Art of Blazonry, by a very good Hand, London, E. Tyler, 1661.1 quotations
Having made your hand fit and ready in generall proportion, learn to give all bodies their true shadows according to their eminence and concavity, and to heighthen or deepen, as your body appeareth nearer or farther from the light ; which is a matter of great judgment, and indeed the soul (as I may say) of a picture.
AGLIONBY, William, Painting Illustrated in Three Diallogues. Containing some Choice Observations upon the Art. Together with The Lives of the Most Eminent Painters From Cimabue, to the time of Raphael and Michael Angelo. With an Explanation of the Difficult Terms, London, John Gain, 1685.1 quotations
When a Painter has acquired any Excellency in Desinging, readily and strongly ; What has he to do next ?
That is not half his Work, for then he must begin to mannage his Colours, it being particularly by them, that he is to express the greatness of his Art. ’Tis they that give, as it were, Life and Soul to all that he does ; without them, his Lines will be but Lines that are flat, and without a Body, but the addition of Colours makes that appear round ; and as it were out of the Picture, which else would be plain and dull. ’Tis they that must deceive the Eye, to the degree, to make Flesh appear warm and soft, and to give an Air of Life, so as his Picture may seem almost to Breath and Move.
Did ever any Painter arrive to that Perfection you mention ?
Yes, several, both of the Antient and Modern Painters. Zeuxis Painted Grapes, so that the Birds flew at them to eat them. Apelles drew Horses to such a likeness, that upon setting them before live Horses, the Live ones Neighed, and began to kick at them, as being of their own kind. And amongst the Modern Painters, Hannibal Carache, relates to himself, That going to see Bassano at Venice, he went to take a Book off a Shelf, and found it to be the Picture of one, so lively done, that he who was a Great Painter, was deceived by it. The Flesh of Raphael’s Pictures are so Natural, that this seems to be Alive. And so do Titians Pictures, who was the Greatest Master for Colouring that ever was, having attained to imitate Humane Bodies in all the softness of Flesh, and beauty of Skin and Complexion.
