Foretold that there would be a solar eclipse in that year, as stated by Herodotus.
For the Algol variables it is possible to form even more direct calculations of the density, for from the duration of the eclipse an approximate estimate of the size of the star may be made.
When the eclipse is total, there is a real geometrical shadow - very small compared with the penumbra (for the apparent diameters of the sun and moon are nearly equal, but their distances are as 370: I); when the eclipse is annular, the shadow is all penumbra.
He dallied till the end of August, many weeks after the defeat, when the coming of Syracusan reinforcements decided him to depart; but on the 27th of that month was an eclipse of the moon, on the strength of which he insisted on a delay of almost another month.

Accordingly, in 1867, Smith was appointed assistant in the Assyriology department, and the earliest of his successes was the discovery of two inscriptions, one fixing the date of the total eclipse of the sun in the month Sivan in May 763 B.C., and the other the date of an invasion of Babylonia by the Elamites in 2280 B.C. In 1871 he published Annals of Assur-bani-pal, transliterated and translated, and communicated to the newlyfounded Society of Biblical Archaeology a paper on "The Early History of Babylonia," and an account of his decipherment of the Cypriote inscriptions.
The decisive battle, in the sixth year, was interrupted by the famous solar eclipse on the 28th of May 585 predicted by Thales.
II.), by means of which Assyrian chronology is fixed from 911 B.C. to 666 B.C., the solar eclipse of June 15th, 763 B.C., which is recorded in the eponymy of Pur-Sagale, placing the dead reckoning for these later periods upon an absolutely certain basis.
His pupil, Rainer Gemma-Frisius, used it for the observation of the solar eclipse of January 1544 at Louvain, and fully described the methods he adopted for making measurements and drawings of the eclipsed sun, in his De Radio Astronomico et Geometrico (1545).
Soon afterwards, but Grant's own fortunes suffered a temporary eclipse owing to a disagreement with Halleck.
Subtract 413 from 777, the remainder is 364; and 364 divided by four gives 91 without a remainder; consequently the eclipse happened in the fourth year of the ninety-first Olympiad, which is the date to which it is referred by Thucydides.
In 1862 he received the gold medal of the latter society, and in 1864 a Royal medal from the Royal Society, for his observations on the total eclipse of the sun in 1860, and for his improvements in astronomical photography.
So little was the scientific conception of the solar system familiar to Epicurus that he could reproach the astronomers, because their account of an eclipse represented things otherwise than as they appear to the senses, and could declare that the sun and stars were just as large as they seemed to us.
In the case of any subject-kind, its definition and its existence being avouched by vas, "heavenly body" for example, the problem is, given the fact of a non-self-subsistent characteristic of it, such as the eclipse of the said body, to find a ground, a / .t aov which expressed the a'irwv, in virtue of which the adjectival concept can be exhibited as belonging to the subjectconcept Kau' a&rO in the strictly adequate sense of the phrase in which it means also?7 abrO.
In 1743, from the circumstance that an eclipse not visible in Philadelphia because of a storm had been observed in Boston, where the storm although north-easterly did not occur until an hour after the eclipse, he surmised that storms move against the wind along the Atlantic coast.
In 1860 De la Rue took the photoheliograph to Spain for the purpose of photographing the total solar eclipse which occurred on the 18th of July of that year.
For these reasons the coelostat is never likely to be largely employed in general astronomical work, but it is admirably adapted for spectroscopic and bolometric observations of the sun, and for use in eclipse expeditions.
Various dates - ranging from 625 B.C. to 583 B.C. - have been assigned by different chronologists to this eclipse; but, since the investigations of Airy,2 Hind, 3 and Zech, 4 the date determined by them (May 28, 585 B.C.) has been generally accepted (for later authorities see Eclipse and Astronomy).
She found the maestro towards the end of 1837 dispirited by a temporary eclipse of popularity and in the first stage of his fatal malady, and carried him off to winter with her in the south.
Archimedes concluded from his measurements that the sun's diameter was greater than 27' and less than 32'; and even Tycho Brahe was so misled by his measures of the apparent diameters of the sun and moon as to conclude that a total eclipse of the sun was impossible.'
The happy coincidence of a lunar eclipse gives us the 20th of September 331 as the exact day upon which the Macedonian army crossed the Tigris.
It was mainly accident which determined that from the 12th to the 17th century Avicenna should be the guide of medical study in European universities, and eclipse the names of Rhazes, Ali ibn al-Abbas and Avenzoar.
On the other hand he is quoted by Theon of Alexandria (who observed an eclipse at Alexandria in A.D.
But he seems to have been well cared for, and he was at the age of fourteen sufficiently advanced "in algebra, geometry, astronomy, and even the higher mathematics," to calculate a solar eclipse within four seconds of accuracy.
At the great Indian eclipse of 1868 he demonstrated the gaseous nature of the red prominences, and devised a method of observing them under ordinary daylight conditions.
Assyrian chronology is, therefore, certain from 911 B.C. to 666, and an eclipse of the sun which is stated to have been visible in the month Sivan, 763 B.C., is one that has been calculated to have taken place on the 15th of June of that year.
The amplitude of the phase is 1ï¿½1 magnitude; and the absence of any stationary interval at minimum proves the eclipse to be partial, not annular.
32-33), besides a great earthquake in Bithynia, an eclipse so remarkable that it became night " at the sixth hour of the day."
The eclipse meant is, presumably, that of the Crucifixion (so Origen, contra Celsum, ii.

He looked on the age in which he lived as a period of transition, to be followed either by an " eclipse of faith " or by a " revival of Christianity in a wider aspect," a " catholic, comprehensive, all-embracing Christianity " that " might yet overcome the world.
Among the Greeks, whose literature never suffered a complete eclipse, a similar effort to restore the classical tongue resulted in a kind of compromise; the conventional literary language, which is neither ancient nor modern, differs widely from the ver nacular.
The second part of the statement of Herodotus - the reality of the prediction by Thales - has been frequently called in question, chiefly on the ground that, in order to predict a solar eclipse with any chance of success, one should have the command of certain astronomical facts which were not known until the 3rd century, B.C., and then merely approximately, and only employed with that object in the following century by Hipparchus.
His observations of the protuberances on the sun, made during the total eclipse on the 10th of July 1860, are included in the work of Madler on the eclipse, published in 1861.
The most complete hydrogen spectrum is that measured by Evershed 8 in the flash spectrum observed during a total solar eclipse, and contains thirty-one lines, all of which agree with considerable accuracy with the formula, if the frequency number n is calculated correctly by reducing the wave-length to vacuo.9 It is a characteristic of Balmer's formula that the frequency approaches a definite limit as s is increased, and it was soon discovered that in several other spectra besides hydrogen, series of lines could be found, which gradually come nearer and nearer to each other as they become fainter, and approach a definite limit.
