— The Decameron, Vol. II. • Giovanni Boccaccio

... in which there seems to be an imperfect relation between Nature's effects and those of pigments, we will briefly refer to the great discrepancy occasioned by the luminosity of light. In all the lower effects of light, in the illumination of Nature and the revelation of colored surfaces, in the exquisite play and power of reflected light and color, and in the depth and richness ...

... emphasizing them. Keeping in mind the fact that the Palace contains little American art earlier than 1905, American artists are showing marked individualities, even in their acceptance of popular precepts. The virile men of the day love luminosity; it dominates all else, and marks their canvases with light; they restrain the too bold stroke of the radical Impressionist, but outline with firmness, so that details are more easily imagined by the observer, even when ...

... school when the master enters unexpectedly, and there near the open doors of his headquarters stood the master himself. Even without that sudden silence, and the scramble to their feet of those upon the benches, I felt that I should have known instantly that he was present. There was a pale luminosity about his ivory face which drew the eye towards it, and though his dress might be the plainest of a hundred, his appearance would be the first which one would notice. There he was, with his little plump, heavy-shouldered figure, his green coat with the red collar and cuffs, his white, well-formed ...

... leaned to help him in to the boat. Gudrun again watched Gerald climb out of the water, but this time slowly, heavily, with the blind clambering motions of an amphibious beast, clumsy. Again the moon shone with faint luminosity on his white wet figure, on the stooping back and the rounded loins. But it looked defeated now, his body, it clambered and fell with slow clumsiness. He was breathing hoarsely too, like an animal that is suffering. He sat slack and motionless in the ...

... He even assigned to each an approximate period of half a century. "I adhere to the conviction," he wrote later to Humboldt, "that Procyon and Sirius form real binary systems, consisting of a visible and an invisible star. There is no reason to suppose luminosity an essential quality of cosmical bodies. The visibility of countless stars is no argument against the invisibility of ...

... mediocre. He introduced a discordant pathological note, but the music of Richard Strauss may save his pasticcio. It interprets the exotic prose of the Irishman with tongues of fire; it laps up the text, encircles it, underlines, amplifies, comments, and in nodules of luminosity, makes clear that which is dark, ennobles much that is vain, withal it never insists on leading; the composer appears to follow the poet.) Laforgue's Salome tries to sport with the head of John the Baptist, stumbles, loses her footing, and falls from the machicolated wall on jagged rocks below, ...

... luminous even when still contained in the mother's womb. If I happen by accident to crush a female big with germs that have reached maturity, a shiny streak runs along my fingers, as though I had broken some vessel filled with a phosphorescent fluid. The lens shows me that I am wrong. The luminosity comes from the cluster of eggs forced out of the ovary. Besides, as laying-time approaches, the phosphorescence of the eggs is already made manifest through this clumsy midwifery. A soft opalescent light shines through the ...

... the same chemical materials as those with which we are familiar upon the earth. A part of the dazzling brilliance of the noonday sun is due to the vapor of iron floating in his atmosphere, and the faint luminosity of the remotest cloudlike nebula is the glow of just such hydrogen as enters into every drop of water ...

... horizon of our northern middle latitudes, in summer, where the Milky Way breaks up into vast sheets of nebulous luminosity, lying over and between the constellations Scorpio and Sagittarius, there is a remarkable assemblage of "coal-sacks,'' though none is of great size. One of them, near a conspicuous star-cluster in Scorpio, M80, is interesting for having been the first of these strange objects noted by Herschel. ...

... hands and threw it into the air, it appeared like sparkles of fire, so long did it retain its brilliancy. The slightest movement in the water caused a flash of light. Jerry and I agreed that we had never seen anything more beautiful. The doctor told us that this phosphorescence or luminosity of the ocean is caused by a minute animal, scarcely perceptible to the naked eye, though sufficient to tinge the water of a brown or reddish colour. Other marine substances are, however, luminous. While we were waiting to step into the boat, the bay having ...

... Pyrophorus, the large tropical firefly which has the seat of its luminosity on the upper surface of the thorax, nothing definite appears to be known; but it has been said that this instinct is altogether nocturnal.

The ordinary research paper, when it is not extravagant theorizing, is apt to be rather sawdusty in texture, and Ann Veronica was delighted to find the same easy and confident luminosity that distinguished his work for the general reader.

... Russian sons of Anak, Friedrich Wilhelm grudged not to send German smiths, millwrights, drill-sergeants, cannoneers, engineers; having plenty of them. By whom, as Peter well calculated, the inert opaque Russian mass might be kindled into luminosity and vitality; and drilled to know the Art of War, for one thing. Which followed accordingly. And it is observable, ever since, that the Russian Art of War has a tincture of GERMAN in it (solid German, as contradistinguished from unsolid Revolutionary-French); ...

... the name heaven is applied to a body that participates in any property of the heavenly body, as sublimity and luminosity, actual or potential. Thus Damascene (De Fide Orth. ii) holds as one heaven all the space between the waters and the moon's orb, calling it the aerial. According to him, then, there are three heavens, the aerial, the starry, and one higher than both these, of which ...

That inner world, to which by long effort he had learned the way, was all alight with agony; it was bitter as brine, it was of that pale luminosity that is the utmost product of pain, it hummed in his ears with a note that rose to a scream ... it pressed upon him, penetrated him, stretched him as on a rack.... And with that his will grew sick ...

... large, lambent, blue eyes. All these things rushed over the thrilled little secretary with an effect, as already described, of a certain bewilderment, that left no single, dominant impression. What remained with him, perhaps, most vividly, he says, was the quality of the big blue eyes, their luminosity, their far-seeing expression, their kindliness. They were the eyes of the true visionary, but in such a personality they proclaimed the mystic who had retained his health of soul and body. Mr. Skale was surely a visionary, but just as surely a wholesome man of action—probably ...

... structure, in order that both the one function and the other may be well performed. And so, although all forms of kinetic energy (and among them zoo-dynamic, or the force of animal life) manifest warmth and luminosity as qualities, science attributes animal heat to chemic force and refuses to consider that perhaps zoo-dynamic uses chemico-dynamic for its own purposes, even if these purposes are unconscious, because the higher force always dominates the lower. Properly speaking, science ...

... pure Brahman is devoid of any form or mode. The notion of d@rs'yatva (objectivity) carries with it also the notion of ja@datva (materiality) or its nature as non-consciousness (ajnanatva) and non-selfness (anatmatva) which consists in the want of self-luminosity of objects of consciousness. The relation of consciousness (jnana) to its objects cannot be regarded as real but as mere illusory impositions, for as we shall see later, it is not possible to determine the relation between knowledge and ...

... compare with the beauty of Hili-li vegetation in October and November. I should imagine from what he says that the coloring of vegetation is in great part the merest tintage, the large admixture of white giving to it a startling luminosity, and permitting the fullest effect of those neutral tints which are capable of combinations at once so restful and so pleasing to the refined eye. In the vegetation of Florida there is luminosity; but chromatic depth, as in most tropical coloring, is the ...

Thus of samples of meat bought in Prague and kept in a cool room for about two days, luminosity was present in 52% of the samples in the case of beef, 50% ...

... good remained to form among themselves a heavenly society; but the evil were cast into the hells. Afterwards I saw that that flaming radiance descended to the lower parts of the earth there to a considerable depth, and then it appeared at one time in a flaming [lustre] verging to luminosity, at another time in a luminosity verging into obscurity, and at another in obscurity: and I was told by the angels that that appearance is according to the reception of truth from good, and of falsity from evil, with those who inhabit the lower parts ...

There, on those vast plains, they were to describe enormous geometric figures, drawn in characters of reflecting luminosity, among which was the proposition regarding the 'square of the hypothenuse,' commonly called the 'Ass's Bridge' by the French.

... separates a rational process, resulting in manly resolve, from a weakly sentiment that finds occasional hysterical utterance. The Monroe Doctrine, as popularly apprehended and indorsed, is a rather nebulous generality, which has condensed about the Isthmus into a faint point of more defined luminosity.

... question might then have been asked—"Why do we not see it?"—we, especially, who occupy the mid region of the cluster—the very locality near which, at least, must be situated this inconceivable central sun. The astronomer, perhaps, at this point, took refuge in the suggestion of non-luminosity; and here analogy was suddenly let fall. But even admitting the central orb non-luminous, how did he manage to explain its failure to be rendered visible by the incalculable host of glorious suns glaring in all directions ...

The vision screen was now a blur of writhing mist, lighted by the sun and torn at by emptiness. There was luminosity where the ships had encountered each other. It was sunshine upon thin smoke. It was like the insanely enlarging head of a newborn comet, whose tail would be formed presently by light-pressure. The Plumie ship was almost invisible behind the ...

Its brightness is much greater in some places than in others; the central parts are, generally speaking, the most brilliant, and the luminosity gradually fades away as the edge of the nebula is approached. In fact, we can hardly say that the nebula has any definite boundary, for with each increase of telescopic power faint new branches can be seen. There seems to be an empty space in the nebula immediately surrounding ...
