[26] The reader will observe that I am speaking at present of mere material qualities. If he would obtain perfect ideas respecting loveliness of luminous surface, let him closely observe a swan with its wings expanded in full light five minutes before sunset. The human cheek or the rose leaf are perhaps hardly so pure, and the forms of snow, though individually as beautiful, are less exquisitely combined. [27] [Greek: hos d' ote tis t' elephanta gyne phoiniki miene Meonis.] So Spenser of Shamefacedness, an exquisite piece of glowing color--and sweetly of Belphoebe--(so the roses and lilies of all poets.) Compare the making of the image of Florimell. "The substance whereof she the body made Was purest snow, in massy mould congealed, Which she had gathered in a shady glade Of the Riphoean hills. The same she tempered with fine mercury, And mingled them with perfect vermily." With Una he perhaps overdoes the white a little. She is two degrees of comparison above snow. Compare his questioning in the Hymn to Beauty, about that mixture made of colors fair; and goodly temperament, of pure complexion. "Hath white and red in it such wondrous power That it can pierce through the eyes into the heart?" Where the distinction between typical and vital beauty is very gloriously carried out. [28] I have not spoken here of any of the associations connected with warmth or coolness of color, they are partly connected with vital beauty, compare Chap. xiv. Sec. 22, 23, and partly with impressions of the sublime, the discussion of which is foreign to the present subject; purity, however, it is which gives value to both, for neither warm nor cool color, can be beautiful, if impure. Neither have I spoken of any questions relating to melodies of color, a subject of separate science--whose general principle has been already stated in the seventh chapter respecting unity of sequence. Those qualities only are here noted which give absolute beauty, whether to separate color or to melodies of it--for all melodies are not beautiful, but only those which are expressive of certain pleasant or solemn emotions; and the rest startling, or curious, or cheerful, or exciting, or sublime, but not beautiful, (and so in music.) And all questions relating to this grandeur, cheerfulness, or other characteristic impression of color must be considered under the head of ideas of relation. CHAPTER X.
