Iris (eye)

“ When there is very little light, and it is necessary to let in as much as possible, the ring expands and the pupil grows large. The best way to observe this is to look at a cat's eyes in the dusk, and then bring her near to a bright light; for [Pg 31] the iris of a cat's eye contracts and expands much more than ours does."

“ The presence of the iris greatly diminishes the extent of surface designed for the reception of light; the whole pencil of rays that falls on the cornea, as supposed, in Fig. 3, not reaching the retina, but only as shown in Fig. 4, on that section of it which enters the pupil. Though much of the volume of light is thereby lost, the restriction is highly beneficial, by sharpening the image on the retina; for the refraction of the rays is much more equal in the centre than toward the margin. ”

“ The eye—which sees all objects reversed—retains the images for some time. This conclusion is proved by the results; because, the eye having gazed at light retains some impression of it. After looking (at it) there remain in the eye images of intense brightness, that make any less brilliant spot seem dark until the eye has lost the last trace of the impression of the stronger light. ”

“ And then, in the blowing clouds, she saw a band of faint iridescence colouring in faint colours a portion of the hill. And forgetting, startled, she looked for the hovering colour and saw a rainbow forming itself. In one place it gleamed fiercely, and, her heart anguished with hope, she sought the shadow of iris where the bow should be. Steadily the colour gathered, mysteriously, from nowhere, it took presence upon itself, there was a faint, vast rainbow. ”

“ The hues of the opal, the light of the diamond, are not to be seen, if the eye is too near. ”

“ millions of millions of vibrations have penetrated the eye before the eye can distinguish the tints of a violet. ”

“ The eye which turns from a white object in the light of the sun and goes into a less fully lighted place will see everything as dark. ”

“ I dislike an eye that twinkles like a star. Those only are beautiful which, like the planets, have a steady, lambent light;--are luminous, but not sparkling. ”

“ It is impossible that the eye should project from itself, by visual rays, the visual virtue, since, as soon as it opens, that front portion [of the eye] which would give rise to this emanation would have to go forth to the object and this it could not do without time. And this being so, it could not travel so high as the sun in a month's time when the eye wanted to see it. ”

“ I think it was his eye! yes, it was this! One of his eyes resembled that of a vulture—a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—I made up my mind to take the life of the old man, and thus rid myself of the eye for ever. ”

“ One day, riding along, we were talking about Joan's great talents, and he said, 'But, greatest of all her gifts, she has the seeing eye.' I said, like an unthinking fool, 'The seeing eye?—I shouldn't count on that for much—I suppose we all have it.' 'No,' he said; 'very few have it.' Then he explained, and made his meaning clear. He said the common eye sees only the outside of things, and judges by that, but the seeing eye pierces through and reads the heart and the soul, finding there capacities which the outside didn't indicate or promise, and which the other kind of eye couldn't detect. ”

“ It is no secret that the moon has no light of her own, but is, as it were, a mirror, receiving brightness from the influence of the sun. ”

“ Light is the chaser away of darkness. Shade is the obstruction of light. Primary light is that which falls on objects and causes light and shade. And derived lights are those portions of a body which are illuminated by the primary light. A primary shadow is that side of a body on which the light cannot fall. ”

“ It would be worth the while to look closely into the eye which has been open and seeing at such hours, and in such solitudes, its dull, yellowish, greenish eye. Methinks my own soul must be a bright invisible green. ”

“ The red rose whispers of passion,
And the white rose breathes of love;
Oh, the red rose is a falcon.
And the white rose is a dove. ”

“ The instant the atmosphere is illuminated it will be filled with an infinite number of images which are produced by the various bodies and colours assembled in it. And the eye is the target, a loadstone, of these images. ”

“ The moon pull'd off her veil of light,905
That hides her face by day from sight.
Mysterious veil, of brightness made,
That's both her lustre and her shade, [160]
And in the lanthorn of the night,
With shining horns, hung out her light: [161] 910
For darkness is the proper sphere [162]
Where all false glories use t' appear. ”

“ The eye is continually influenced by what it cannot detect; nay, it is not going too far to say, that it is most influenced by what it detects least. Let the painter define, if he can, the variations of lines on which depend the changes of expression in the human countenance. ”

“ A single and distinct luminous body causes stronger relief in the object than a diffused light; as may be seen by comparing one side of a landscape illuminated by the sun, and one overshadowed by clouds, and so illuminated only by the diffused light of the atmosphere. ”

“ Why make so much of fragmentary blue
In here and there a bird, or butterfly,
Or flower, or wearing-stone, or open eye,
When heaven presents in sheets the solid hue? ”

“ What seems to us for us is true.
The planet has no proper light,
And yet, when Venus is in view,
No primal star is half so bright. ”

“ THE BODY WHICH IS NEAREST TO THE LIGHT CASTS THE LARGEST SHADOW, AND WHY? If an object placed in front of a single light is very close to it you will see that it casts a very large shadow on the opposite wall, and the farther you remove the object from the light the smaller will the image of the shadow become. ”

“ Roses, wild roses, everywhere! So plentiful were they, they not only perfumed the air, they seemed to dye it a faint rose-hue. The colour floated abroad with the scent, and clomb, and spread, until the whole west blushed and glowed with the gathered incense of roses. And my heart fainted with longing in my bosom.
Could I but see the Spirit of the Earth, as I saw once the in dwelling woman of the beech-tree, and my beauty of the pale marble, I should be content. Content!—Oh, how gladly would I die of the light of her eyes! ”

“ No small hole can so modify the convergence of rays of light as to prevent, at a long distance, the transmission of the true form of the luminous body causing them. ”

“ White roses and red roses: those were beautiful colours to think of. And the cards for first place and second place and third place were beautiful colours too: pink and cream and lavender. Lavender and cream and pink roses were beautiful to think of. Perhaps a wild rose might be like those colours and he remembered the song about the wild rose blossoms on the little green place. But you could not have a green rose. But perhaps somewhere in the world you could. ”

“ A shadow will appear dark in proportion to the brilliancy of the light surrounding it and conversely it will be less conspicuous where it is seen against a darker background. ”

“ Lovely eyes in colour, lovely eyes in form—large and tender and quietly thoughtful—but beautiful above all things in the clear truthfulness of look that dwells in their inmost depths, and shines through all their changes of expression with the light of a purer and a better world. ”

“ I ask how far away the eye can discern a non-luminous body, as, for instance, a mountain. It will be very plainly visible if the sun is behind it; and could be seen at a greater or less distance according to the sun's place in the sky. ”

“ It was marvellous, a feast for the eyes, this complication of coloured tints, a perfect kaleidoscope of green, yellow, orange, violet, indigo, and blue; in one word, the whole palette of an enthusiastic colourist! ”

“ Shadow is the absence of light, merely the obstruction of the luminous rays by an opaque body. Shadow is of the nature of darkness. Light [on an object] is of the nature of a luminous body; one conceals and the other reveals. They are always associated and inseparable from all objects. But shadow is a more powerful agent than light, for it can impede and entirely deprive bodies of their light, while light can never entirely expel shadow from a body, that is from an opaque body. ”

“ Thus, when the lamp that lighted
The traveller at first goes out,
He feels awhile benighted.
And looks round in fear and doubt.
But soon, the prospect clearing,
By cloudless starlight on he treads,
And thinks no lamp so cheering
As that light which Heaven sheds. ”

“ I sometimes wonder if the hand is not more sensitive to the beauties of sculpture than the eye. I should think the wonderful rhythmical flow of lines and curves could be more subtly felt than seen. Be this as it may, I know that I can feel the heart-throbs of the ancient Greeks in their marble gods and goddesses. ”

“ Over the sod.—I do love violets:
They tell the history of woman's love;
They open with the earliest breath of spring;
Lead a sweet life of perfume, dew, and light;
And, if they perish, perish with a sigh
Delicious as that life. ”

“ The eyes themselves were of that baffling protean gray which is never twice the same; which runs through many shades and colorings like intershot silk in sunshine; which is gray, dark and light, and greenish gray, and sometimes of the clear azure of the deep sea. They were eyes that masked the soul with a thousand guises, and that sometimes opened, at rare moments, and allowed it to rush up as though it were about to fare forth nakedly into the world on some wonderful adventure,—eyes that could brood with the hopeless sombreness of leaden skies; ”

“ And the eye can best distinguish the forms of objects when it is placed between the shaded and the illuminated parts. ”

“ RED ROSES.
A cool red rose and a pink cut pink, a collapse and a sold hole, a little less hot. ”

“ Of several colours, all equally white, that will look whitest which is against the darkest background. And black will look intensest against the whitest background.
And red will look most vivid against the yellowest background; and the same is the case with all colours when surrounded by their strongest contrasts. ”

“ "Why, what a wonderful piece of luck!" he cried; "here is a red rose! I have never seen any rose like it in all my life. It is so beautiful that I am sure it has a long Latin name;" ”

“ Though many a flower may win my praise,
The violet has my love;
I did not pass my childish days
In garden or in grove:
My garden was the window-seat,
Upon whose edge was set
A little vase—the fair, the sweet—
It was the violet. ”

“ With roses yellow, red, and white.
But, O my child, beware, beware!
Touch not the blossoms blowing there,
For every rose a thorn doth bear. ”

“ "when I came to you out of all that dust and heat and toil, I positively smelt violets at once. But not the sweet violet -- you know, that early dark violet that smells of melting snow and spring grass." ”

“ Red Rose, proud Rose, sad Rose of all my days!
Come near me, while I sing the ancient ways:
Cuchulain battling with the bitter tide;
The Druid, grey, wood-nurtured, quiet-eyed,
Who cast round Fergus dreams, and ruin untold; ”

“ The time comes when we have learned to understand the music of sorrow, the beauty of resigned suffering, the holy light that plays over the pillow of those who die before their time, in humble hope and trust. ”

“ Fill, fill with the rising tide of night;
While the sunset with gold-dust bridges
The black-ravined ridges,
Whose mighty muscles curve in its light.
In our weary climb, while night dyes deep,
Down the broken and stony steep,
How our jaded bodies are shaken
By each step in half-blindness taken —
One's thoughts lie heaped like brutes asleep.
Open the door of the dismal hut,
Silence and darkness lone were shut
In it, as a tidal pool, until returning
Night drowns the land, — no ember's burning, —
One is too weary the food to cut. ”

“ How fair is the Rose! what a beautiful flower!
The glory of April and May:
But the leaves are beginning to fade in an hour,
And they wither and die in a day.
Yet the Rose has one powerful virtue to boast,
Above all the flowers of the field!
When its leaves are all dead and fine colours are lost,
Still how sweet a perfume it will yield! ”

“ The rose is fragrant, but it fades in time;
The violet sweet, but quickly past the prime; ”

“ These vessels of verse, O Great Goddess, are filled with invisible tears,
With the sobs and sweat of my spirit and her desolate brooding for years;
See, I lay them — not on thine altar, for they are unpolished and plain,
Not rounded enough by the potter, too much burnt in the furnace of pain;
But here in the dust, in the shadow, with a sudden wild leap of the heart
I kneel to tenderly kiss them, then in silence arise to depart.
I linger awhile at the portal with the light of the crimsoning sun
On my wreathless brow bearing the badges of battles I've fought in not won. ”
