Bela reached the apogee of his political greatness in 1264 when, shortly after his crushing defeat of the Servian king, Stephen Urosh, he entertained at his court, at Kalocsa, the ambassadors of the newly restored Greek emperor, of the kings of France, Bulgaria and Bohemia and three Tatar mirzas.
The problem of determining an orbit may be regarded as coeval with Hipparchus, who, it is supposed, found the moving positions of the apogee and perigee of the moon's orbit.
A line joining the moon in perigee and in apogee is called the " line of apsides."
In the course of the next few months he gathered into his hands every branch of the government: he had reached the apogee of his short-lived greatness.
The task, however, was so gigantic that after 150 years of strenuous effort, at the period which may be considered as the apogee of its power, that is, in the first half of the 13th century, the papacy had attained only incomplete results.
Damascus, Kuf a and Basra will attract the flower of all the Moslem provinces, and thus that great intellectual, literary and scientific movement, which reached its apogee under the first Abbasid Caliphs at Bagdad, steadily becomes more marked.
The apogee of palace poetry dates from 1275 to 1280, when young King Diniz displayed his exceptional talents in a circle formed by the best troubadours of his father Alphonso III.
One of the most critical spirits of the age, his chronicle of King Manoel, the Fortunate Monarch, which he introduced by one of Prince John, afterwards King John II., is worthy of the subject and the reign in which Portugal attained the apogee of its greatness.
Apogee, Apocentre, Aposaturnium, &c. are terms applied to those points of the orbit of a body moving around a.
Hipparchus fixed the chief data of astronomy - the lengths of the tropical and sidereal years, of the various months, and of the synodic periods of the five planets; determined the obliquity of the ecliptic and of the moon's path, the place of the sun's apogee, the eccentricity of his orbit, and the moon's horizontal parallax; all with approximate accuracy.
The eccentricity of the ellipse is in the general average about 0.055, whence the moon is commonly more than i' further from the earth at apogee than at perigee.
Thus the apogee and perigee became two definite points of the orbit, indicated by the variations in the angular motion of the moon.
In astronomy, the term is used in connexion with the Ptolemaic theory to denote the angular distance on the epicycle of a planet from the true apogee of the epicycle; and the "equation to the argument" is the angle subtended at the earth by the distance of a planet from the centre of the epicycle.
