Pythagoras Heraclides of Pontus, Greek philosopher of 4th century AD, was the first to explain that the apparent rotation of the heavens is brought about by rotation of the earth on its axis rather than by the passage of stars around the Earth. He proposed that the seeming westward movement of the heavenly bodies is due to the eastward rotation of the Earth on its axis.

THE LOST KNOWLEDGE OF THE GREEKS During the first decade of the 16th century when Copernicus was still forming his astronomical hypotheses, he read the works of many Greek authors and found that heliocentric ideas had already been propounded. He mentions in his work some of those Greek mathematician-astronomers who held distinctly different views of the celestial system from that of Aristotle and Ptolemy, although not necessarily heliocentric, such as Philolaus, Hicetus, Ecphantus, and Heraclides ("On the Revolutions of the Celestial Spheres", Book One). Indeed, the geocentric theories were not the only systems known to the Greeks, nor even at times the most accepted. Between the sixth and fourth century B.C., there was a philosophical society known as the Pythagorean society in Greece. Pythagoras of Samos (c. 582-500 B.C.), founder of the society, traveled extensively in his youth by way of the sea to the East as well as to Egypt, and not only accumulated a wealth of knowledge from different corners of the Earth but also obtained a unique perspective that was possible only for the celestial navigator-businessmen of the time, i.e., the sphericity of the Earth. Astronomy and mathematics, particularly trigonometry, originated to a great measure among those celestial navigator-businessmen of antiquity whose survival almost entirely depended upon knowing the relative positions and movements of the celestial bodies. Furthermore, while traveling across the sea by observing the movements of the celestial spheres, it became revealingly clear to them that the Earth was a spherical entity. (Around 200 B.C., three hundred years after Pythagoras, Phoenician navigator-businessmen circumnavigated the Earth for the first time in recorded history and proved that the Earth was indeed spherical, preceding Magellan by more than 1700 years.)

ASTRONOMERS I t is easy to forget sometimes how much of our knowledge we owe to the civilizations that came before us. Most of modern science can trace its roots back to the theories and philosophies of ancient scholars. The ancient Greeks molded many of the ideas that shaped the modern world, including the field of astronomy . One of the most important facts to remember when discussing ancient Greek astronomy is that the ancient Greeks lacked any sort of device to magnify the heavens, such as telescopes and binoculars . They had to make all their observations using only the naked eye . The Greeks carefully recorded everything they saw in the heavens and most of their theories were developed over long periods of time using the information they had written down about celestial occurrences . Greek astronomers were very scientific in their work. They studied the heavens because they believed that there was a natural order to everything in the cosmos and wished to explore it.. THALES: Thales was the first prominent Greek astronomer. He was originally from Greek Ionia and not from Mainland Greece. Ionia is on the coast of present-day Turkey (Asia Minor). Thales' best known accomplishment was

Famous in antiquity for the literary and artistic merit of dialogues ranging in subject matter from myths and music to Pythagoras, he has attracted the attention of modern scholars by his obscure theory of matter and an astronomical hypothesis which seems to have partly anticipated Aristarchus and Kepler. In this study Gottschalk attempts to reconstruct the thought of Heraclides (sometimes called Ponticus), beginning with an introductory chapter on his life and writings. The book goes on to deal at length with the dialogue, Heraclides' corpuscular theory of matter, the astronomical fragments, ethical and religious fragments, including his influential contribution to the legend of Pythagoras, and historical and literary studies. back to list of reprints > back to home page >

Contact details Current Research Interests The main focus of my research activity in recent years has been an ongoing research project on rhetoric in late antiquity. During the two years 2001-2003, thanks to the award of a British Academy Research Readership, I was able to complete a book ( Menander: a rhetor in context ) on the third-century rhetorician Menander of Laodicea (Menander Rhetor), evaluating the evidence for his commentary on Demosthenes and setting his work in a number of broader contexts (including the development of rhetorical theory in the second and third centuries, the rhetorical classroom and its teaching practices, and the broader social context). Now that Menander is complete, the focus of current research is moving to Aristotle's Poetics and to ancient interpretations of Homer. I retain an active interest in Greek Tragedy and Old Comedy. Publications Note: a thematically organised list with abstracts is also available.

18. Timeline Related To Greek Science And Technology heraclides of pontus (390322) BC says that Mercury and Venus rotate around the Sun. Earth rotates around its axis and is the center of the Universe. http://www.mlahanas.de/Greeks/TLAstronomy.htm

Timeline related to Greek Astronomy About 600 BC Pherekydes, the teacher of Pythagoras , performed astronomical measurements with a heliotropion device in the island of Syros. (Herodotus describes later that the Greeks learned to use the Gnomon and Polos from the Egyptians and also the division of the day in 12 parts.) About 585 BC Thales of Miletus (636-546) BC predicts a solar eclipse. About 530 BC Pythagoras gives the name cosmos to the universe. About 520 BC Anaximander proposes that the Earth surface is cylindrical About 500 BC Heraclitus of Ephesus says the Universe is 10800 years old. In 1766 Georges Buffon said that the Earth is older than 6000 years (from fossils). About 470 BC Parmenides says that the Earth shape is spherical Harpalus, Astronomer (?-460) BC About 450 BC Anaxagoras of Athens (500-428) BC taught that the moon shines with the light of the Sun (a hot red stone larger than Peloponese) and so was able to explain the eclipses. Oenopides (500-432) BC measured the inclination of the Earth axis with respect to the ecliptic plane to be 24 degrees, defined the Great Year to be about 59 years, the interval with an exact repetition of days in a year and the lunar cycle with the Sun and Moon in the exact same locations in the sky, accounting not just for months but also its inclination. 450-385 BC Philolaus of Croton, in southern Italy, (c. 470 - c. 385) BC was the precursor of Copernicus in moving the earth from the center of the cosmos and making it a planet, but in Philolaus' system it does not orbit the sun but rather the central fire. Some scholars regard the astronomical system as a significant attempt to try to explain the phenomena, but others see it as primarily of mythic and religious significance. Philolaus is the first to incorporate all five planets commonly known in antiquity into an astronomical scheme in the correct order, which indicates that he was aware of the most up-to-date astronomical data.

Greek Astronomy Facts Herodotus, the Father of History, tells us that once upon a timewhich time, as the modern computator shows us, was about the year 590 B.C. a war had risen between the Lydians and the Medes and continued five years. "In these years the Medes often discomfited the Lydians and the Lydians often discomfited the Medes (and among other things they fought a battle by night); and yet they still carried on the war with equally balanced fortitude. In the sixth year a battle took place in which it happened, when the fight had begun, that suddenly the day became night. And this change of the day Thales, the Milesian, had foretold to the Ionians, laying down as a limit this very year in which the change took place. The Lydians, however, and the Medes, when they saw that it had become night instead of day, ceased from their fighting and were much more eager, both of them, that peace should be made between them." Henry Smith Williams The Beginnings of Greek Science Thales of Miletus gained great fame by predicting an eclipse of the sun of 25th May 585 BC. Today this seems unlikely as the Astronomy as we assume at that time was not developed to be accurate enough to predict such phenomena. Some say that he was just lucky since the Chaldeans told him that every 90 years there is a eclipse of the sun but solar eclipses occur only in narrow regions on earth, unlike lunar eclipses that are visible everywhere.
