Hipparchus of Nicaea was a Greek astronomer, geographer, and mathematician. He is considered the founder of trigonometry, but is most famous for his incidental discovery of precession of the equinoxes. Hipparchus was born in Nicaea, Bithynia, and probably died on the island of Rhodes, Greece. He is known to have been a working astronomer between 162 and 127 BCE.
Timocharis of Alexandria was a Greek astronomer and philosopher. Likely born in Alexandria, he was a contemporary of Euclid.
Cleisthenes, or Clisthenes, was an ancient Athenian lawgiver credited with reforming the constitution of ancient Athens and setting it on a democratic footing in 508 BC. For these accomplishments, historians refer to him as "the father of Athenian democracy." He was a member of the aristocratic Alcmaeonid clan. He was the younger son of Megacles and Agariste making him the maternal grandson of the tyrant Cleisthenes of Sicyon. He was also credited with increasing the power of the Athenian citizens' assembly and for reducing the power of the nobility over Athenian politics.
Hippias was the last tyrant of Athens, ruling from 527 to 510 BC. He was deposed when Cleomenes I of Sparta successfully invaded Athens and forced him to flee to Persia.
Hipparchus was a member of the ruling class of Athens. He was one of the sons of Pisistratus. He was a tyrant of the city of Athens from 528/7 BC until his assassination by the tyrannicides, Harmodius and Aristogeiton in 514 BC.
Harmodius and Aristogeiton were two ancient Athenian lovers who became known as the Tyrannicides, the preeminent symbol of democracy to ancient Athenians after they committed an act of political assassination at the 514 BC Panathenaic Festival. They assassinated Hipparchus, thought to be the last Peisistratid tyrant, though according to Thucydides Hipparchus was not a tyrant but a minister. They also planned to kill the real tyrant of Athens, Hippias, but were unsuccessful.
Hipparchus is the degraded remnant of a lunar impact crater. It was named after the Greek astronomer, geographer and mathematician Hipparchus. It is located to the southeast of Sinus Medii, near the center of the visible Moon. To the south is the prominent crater Albategnius, and to the southwest lies Ptolemaeus, a feature of comparable dimensions to Hipparchus. Horrocks lies entirely within the northeast rim of the crater. Halley is attached to the south rim, and Hind lies to the southeast. To the north-northeast is the bowl-shaped Pickering, and the flooded Saunder is located off the northeast rim. High-resolution images of Hipparchus were obtained by Lunar Orbiter 5 in 1967.
The Hipparchus, or Hipparch, is a dialogue attributed to the classical Greek philosopher and writer Plato. Like many of Plato's original works, Socrates is featured trying to define a single term, "love of gain" in this case, or philokerdēs in the original text.
The Praise Singer is a historical novel by Mary Renault first published in 1978. Its narrator and main character is the real-life lyric poet Simonides of Ceos, whose life spanned the transition from an oral to a written culture in Ancient Greece. Renault's fiction argues that this transition was in part responsible for the cultural flowering known as the Golden Age of Athens—though she also gives credit to Hipparchus, Tyrant of Athens, who attracted talented artists like Simonides to live in his city. Renault depicts him as having the works of Homer set down in writing for the first time.
Hippocrates was an ancient Greek physician of the Age of Pericles, considered one of the most outstanding figures in the history of medicine.
Hippias Major is one of the dialogues of Plato, although its authenticity has been doubted. It belongs to the early dialogues, written while the author was still young. Its precise date is uncertain, although a date of c. 390 BC has been suggested.
Pisistratus or Peisistratus was a ruler of ancient Athens during most of the period between 561 and 527 BC. His unification of Attica, the triangular peninsula of Greece containing Athens, along with economic and cultural improvements laid the groundwork for the later preeminence of Athens in ancient Greece. His legacy lies primarily in his institution of the Panathenaic Games, historically assigned the date of 566 BC, and the consequent first attempt at producing a definitive version of the Homeric epics. Peisistratos' championing of the lower class of Athens is an early example of populism. While in power, he did not hesitate to confront the aristocracy and greatly reduce their privileges, confiscating their lands and giving them to the poor. Peisistratos funded many religious and artistic programs, in order to improve the economy and spread the wealth more equally among the Athenian people.
