Hipparchus of Nicaea

“ EXPULSION OF THE TYRANTS FROM ATHENS (510 B.C.) .—The two sons of Pisistratus, Hippias and Hipparchus, succeeded to his power. At first they emulated the example of their father, and Athens flourished under their parental rule. But at length an unfortunate event gave an entirely different tone to the government. Hipparchus, having insulted a young noble, was assassinated. Hippias escaped harm, but the event caused him to become suspicious and severe. His rule now became a tyranny indeed, and was brought to an end in the following way. ”

“ Of my household furniture let so much as the executors think right be given to Pompylus and let the rest be sold. I also devise Carion to Demotimus, and Donax to Neleus. But Euboeus must be sold. Let Hipparchus pay to Callinus 3000 drachmas. And if I had not seen that Hipparchus had done great service to Melantes and Pancreon and formerly to me, and that now in his private affairs he has made shipwreck, I would have appointed him jointly with Melantes and Pancreon to carry out my wishes. ”

“ Another citizen, Aristogiton, had reasons of his own for wishing ill to Hipparchus: he stimulated his friend Harmodius to a keener sense of the injury, and they resolved to [170] wash away their wrongs in blood. But few associates were admitted to the knowledge of their plot, which was to be executed at the Panathenaic festival, when it was usual for all persons to appear in arms. Hipparchus alone was personally offensive; but to dissolve the tyranny, and to secure themselves from retribution, Hippias was to be involved in his brother’s fate. ”

“ Hipparchus inherited his father's literary tastes. He invited several distinguished poets, such as Anacreon and Simonides, to his court. The people appear to have been contented with their rule; and it was only an accidental circumstance which led to their overthrow and to a change in the government.
Their fall was occasioned by the conspiracy of Harmodius and Aristogiton, who were attached to each other by a most intimate friendship. Harmodius having given offence to Hippias, the despot revenged himself by putting a public affront upon his sister. ”

“ Thereupon, in a frenzy of wrath, Harmodius and Aristogeiton did their celebrated deed, in conjunction with a number of confederates.35 But while they were lying in wait for Hippias in the Acropolis at the time of the Panathenaea (Hippias, at this moment, was awaiting the arrival of the procession, while Hipparchus was organizing its dispatch) they saw one of the persons privy to the plot talking familiarly with him. ”

“ Such is the memorable narrative of Harmodius and Aristogeitôn, peculiarly valuable inasmuch as it all comes from Thucydidês. [219] To possess great power,—to be above legal restraint,—to inspire extraordinary fear,—is a privilege so much coveted by the giants among mankind, that we may well take notice of those cases in which it brings misfortune even upon themselves. The fear inspired by Hipparchus,—of designs which he did not really entertain, but was likely to entertain, and competent to execute without hindrance,—was here the grand cause of his destruction. ”

“ And she was a seller of garlands; and Pisistratus afterwards gave her in marriage to Hipparchus his son, as Clidemus relates in the eighth book of his Returns, where he says—"And he also gave the woman, by name Phya, who had been in the chariot with him, in marriage to his son Hipparchus. And she was the daughter of a man named Socrates. And he took for Hippias, who succeeded him in the tyranny, the daughter of Charmus the polemarch, who was extraordinarily beautiful." ”

“ Hippias being their despot and growing ever bitterer in enmity against the Athenians by reason of Hipparchus’ death, the Alcmeonidae, a family of Athenian stock banished by the sons of Pisistratus, essayed with the rest of the banished Athenians to make their way back by force and free Athens, but could not prosper in their return and rather suffered great hurt. ”

“ He also pointed out how longitude might be determined by observing the eclipses of the sun and moon. This led to the construction of maps; but none have reached us except those which were used to illustrate the geography of Ptolemy. Hipparchus was born B.C. 276, the first who raised geography to the rank of a science. He starved himself to death, being tired of life, like Eratosthenes, more properly an astronomer, and the most distinguished among the ancients, born about 160 B.C., although none of his writings have reached us. ”

“ They say, then, that Hipparchus the Pythagorean, being guilty of writing the tenets of Pythagoras in plain language, was expelled from the school, and a pillar raised for him as if he had been dead. Wherefore also in the Barbarian philosophy they call those dead who have fallen away from the dogmas, and have placed the mind in subjection to carnal passions. “For what fellowship hath righteousness and iniquity?” according to the divine apostle. “Or what communion hath light with darkness? or what concord hath Christ with Belial? or what portion hath the believer with the unbeliever?” ”

“ Again, when Miltiades has to retire from the Chersonese before the return of Darius, he does not go to Athens, from which it follows that Hippias was still tyrant in Athens. Thucydides tells us that when Hippias, after the murder of Hipparchus, was looking about for alliances he married his daughter to Aeantides, the son of Hippoclus, tyrant of Lampsacus, because he saw that Hippoclus was in great repute with Darius. This influence Hippoclus must have gained in the Scythian expedition; he led the ships of his city to the Danube and voted for remaining there. ”

“ Fourteen years had thus passed in peace and prosperity, when Hipparchus gave serious offense to a citizen named Harmo ́dius, who thereupon united with his friend Aristogi ́ton in a plot to murder the two tyrants. Hipparchus was slain. Hippias saved himself by promptness and presence of mind; but from that day his character was changed. His most intimate friends had been accused by the conspirators as concerned in the plot, and executed. Though the charge was false and made only for revenge, the suspicions of Hippias never again slept. ”

“ In order to understand the difficulties of this question Ptolemy says one should read the books of the ancients, and especially those of Hipparchus, whom he praises “as a lover of labour and a lover of truth” (ἀνδρὶ φιλοπόνῳ τε ὁμοῦ καὶ φιλαληθεῖ) . He begins by telling us how Hipparchus was led to discover the precession of the equinoxes; he relates the observations by which Hipparchus verified the eccentricity of the solar orbit imperfectly known to his Chaldaean predecessors, and gives the hypothesis of the eccentric by which he explained the inequality of the sun’s motion. ”

“ True, Eratosthenes stands at the end of the third century, when the great period of advance is over, and the evil genius of Greece gathers strength to rest satisfied with the great things achieved and, by canonising them, to put a stop to further progress. The criticism of Hipparchus, well grounded as it was in the abstract, contributed something to this end by repudiating the good attained and setting hindrances in the way of a greater attainable good, for the sake of a greatest good that was unattainable. Every department of natural science presents much the same spectacle. ”

“ Hipparchus was the first among the Greeks who observ'd some Change in the Constellations with regard to the Equinoxes, or rather who learnt it from the Egyptians. Philosophers ascrib'd this Motion to the Stars; for in those Ages People were far from imagining such a Revolution in the Earth, which was suppos'd to be immoveable in every respect. ”

“ Amongst the Greeks, Hipparchus [A6] deserves particular notice; by an improvement of whose labours Ptolemy formed that system of astronomy which appears to have been the only one studied for ages after, and particularly (as was said before) by the Arabians; who made some improvements of their own, and, if not the inventors, were at least the preservers of astronomy. For with them it took refuge, during those ages of ignorance which involved Europe, after an inundation of northern people had swallowed up the Roman empire ”

“ Delambre doubted, and most subsequent writers follow him here, whether Hipparchus ever so much as visited Alexandria. In any event there seems to be no question that Rhodes may claim the honor of being the chief site of his activities.
It was Hipparchus whose somewhat equivocal comment on the work of Eratosthenes we have already noted. No counter-charge in kind could be made against the critic himself; he was an astronomer pure and simple. His gift was the gift of accurate observation rather than the gift of imagination. ”

“ All these things are patent to the eyes of every man, and require no mathematical investigation; therefore they certainly would have been mentioned by numerous writers both amongst the ancients who have left us histories of Persia, and by the later writers too, who have carried them down to our own time. How, too, would their fertility, which I have described above, harmonize with such a latitude? The facts here advanced are sufficient to give an idea of the learned manner in which Hipparchus attempts to controvert the reasoning of Eratosthenes by mere petitiones principii. ”

“ When we consider all that Hipparchus invented or perfected, and reflect upon the number of his works and the mass of calculations which they imply, we must regard him as one of the most astonishing men of antiquity, and as the greatest of all in the sciences which are not purely speculative, and which require a combination of geometrical knowledge with a knowledge of phenomena, to be observed only by diligent attention and refined instruments. ”

“ Under the Roman empire Nicaea and Nicomedia disputed the title of metropolis of Bithynia. Strabo describes the ancient Nicaea as built regularly, in the form of a square, with a gate in the middle of each side. From a monument in the centre of the city all the four gates were visible at the extremities of great cross-streets. After Constantinople became the capital of the empire Nicaea grew in importance, and after the conquest of Constantinople by the Crusaders became the temporary seat of the Byzantine emperor ”

“ Till at last Nicias falling down to Gylippus, "Let pity, O Gylippus," said he, "move you in your victory; not for me, who was destined, it seems, to bring the glory I once had to this end, but for the other Athenians; as you well know that the chances of war are common to all, and the Athenians used them moderately and mildly towards you in their prosperity." ”

“ Michael, who, by his brother's influence, had been made Archbishop of Athens in 1175, had a similar experience of "Latin" aggressions, and was even forced to retire to the island of Chios. Nicetas, with his family, fled from Constantinople to Nicæa, where he died. Nicetas is the author of several important works concerning Byzantine theology and history. ”

“ He said this in the evening and at dawn the eunuch in attendance on their Majesties' bedchamber announced that the Turks had made an attack upon Nicaea, and shewed them a letter from Eustathius Camytzes, at that time governor of that city, describing what they had done. Immediately, without waiting a little or delaying at all, and as if oblivious of his continuous pains, the Emperor started in a war-chariot for Nicaea, holding the whip himself in his right hand. The soldiers too picked up their spears and marched in orderly bands on either side. ”

“ When the Syracusans returned from Catana, and stood in battle array before the city gates, he rapidly led up the Athenians and fell on them and defeated them, but did not kill many, their horse hindering the pursuit. And his cutting and breaking down the bridges that lay over the river gave Hermocrates, when cheering up the Syracusans, occasion to say, that Nicias was ridiculous, whose great aim seemed to be to avoid fighting, as if fighting were not the thing he came for. ”

“ It was ascertained, on more minute examination, that, some time after the establishment of Christianity by Constantine, [344:1] this monument had been erected in honour of Hippolytus—a learned writer and able controversialist, who bad been bishop of Portus in the early part of the third century, and who had finished his career by martyrdom, about A.D. 236, during the persecution under the Emperor Maximin. Hippolytus is commemorated as a saint in the Romish Breviary ”

“ The simple primitive cathedra, [16] of which we may learn something from the statue of Hippolytus, was, no doubt, “a throne” in the eyes of an ambitious man. Callistus is here charged, by one who knew him and his history, with obtaining this position by knavish words and practices. The question may well arise, in our Christian love for antiquity, How could such things be, even in the age of martyrdoms? Let us recollect, that under the good Bishop Pius, when his brother wrote the Hermas, the peril of wealth and love of money began to be imminent at Rome. ”

“ Pericles, who by solid virtue and the pure force of argument ruled the commonwealth, had stood in need of no disguises nor persuasions with the people. Nicias, inferior in these respects, used his riches, of which he had abundance, to gain popularity. Neither had he the nimble wit of Cleon, to win the Athenians to his purposes by amusing them with bold jests ”
